How to identify and name different ranges in one column in Excel? - excel

I have a recorded drive cycle of a truck which includes speed and coordinates over time. The file looks like this (simplified version)
I want to know the number of times the truck is stopped (when speed = 0) and number them. Therefore, I would like to group the intervals with '0' values (vehicle stopped) in the Speed column and name them in order (Stop 1, Stop 2, etc). Ultimately, my goal would be to somehow be able to calculate the number of stops and duration like this:
Is there any function in Excel which would allow me to do something like that? Thank you.

You can do it using Pivot Tables and a helper column. Also if you have Excel365 with functions like FILTER,UNIQUE and SUMIFS
Formula helper column is just to enumerate properly each group of stops. Notice data need to be sorted properly as your exampel or it won't work:
=IF(D2="STOP";IF(D1="STOP";E1;MAX($E$1:E1)+1);"")
Then pivot table can be inserted:
Helper Column and Vehicle Stop into rows section
Time-step seconds into values section, formated as Time and operation=Sum
Filter field Helper Column to exclude blanks
If you have Excel 365, you can get this output with advanced formulas. In cell J14 formula is:
=UNIQUE(FILTER(D2:D19&E2:E19;D2:D19="STOP"))
And K14 is (and drag down) is:
=SUMIFS($B$2:$B$19;$D$2:$D$19;"STOP";$E$2:$E$19;MID(J14;5;99))
Anyways, I've uploaded the workbook to Gdrive so you can see the Pivot Table and the formulas by yourself. If you don't jave Excel 365, the formulation part may give some errors when you open it:

Just as a postscript to this, you could do the same thing without using helper columns by comparing offset ranges to see where the transitions in speed occurred from 0 to 10 (go) or 10 to 0 (stop). The problem is that normally you would have to go outside the data range (a2:a16 and c2:c16) which gets you either a header cell (a1 or c1) or a blank cell (a17 or c17). In the case of time, there is also a special case where the first time-step is taken to be zero.
All this can be avoided in Excel 365 by using vstack to add appropriate dummy values to the beginning or end of the two ranges:
=LET(timeRange,A2:A16,
speedRange,C2:C16,
timeRange1,VSTACK(A2,timeRange),
speedRange1,VSTACK(1,speedRange),
speedRange2,VSTACK(speedRange,1),
startTime,FILTER(timeRange1,(speedRange1>0)*(speedRange2=0)),
endTime,FILTER(timeRange1,(speedRange1=0)*(speedRange2>0)),
stopTime,endTime-startTime,
label,"STOP "&SEQUENCE(ROWS(stopTime)),
HSTACK(label,stopTime))

How to Mimic Excel Tables Equations / New Row Behavior in Google Sheets

For those of us used to Microsoft Excel who switch to using Google Sheets, there are many differences which need to be taken into account.
One of the nice features in Excel that I miss is tables. If you insert a table into your Excel Spreadsheet, it does a lot of automatic things for you. You can have a single formula for one column of your table, and not have to update it whenever you add new data - whether adding a table row, or adding a row in the middle of the table.
Sometimes (though I haven't figured out why it sometimes does and why it sometimes doesn't) even without tables, Excel will suggest a formula fill as you're entering new data into a row, making copying the formula as easy as pressing "Tab".
There is no functionality in Google Sheets that matches this exactly. When you have a lot of data to enter, having to copy the formulas every single time you add a row is very tedious and time consuming and further leaves open the possibility in making a mistake when transcribing the information and copying / pasting the formulas. Any single cell could have a mistake and you won't know until it causes a problem later, then troubleshooting it will also be time consuming and difficult.
There are various questions in StackOverflow, StackExchange, Google Support and other sites that tackle this issue, but none seem to have a good solution that works for everyone. A lot of people have written an Apps Script do do just this, or use Apps Script + HTML forms as well... but it seems like that shouldn't be necessary, it adds more time & setup, and ends up with a specific solution for that sheet and that sheet only.
So, how can you replicate this behavior in Google Sheets so you don't have to keep copying & pasting your formulas over and over again and save yourself time (and your company money) and make Google Sheets act more like Excel?
BACKGROUND
There is a Google Support Thread on Inserting new Rows which suggests the use of ARRAYFORMULA to do this job. It is not an exact replacement for Excel's functionality, but it can work in most applications. There are other functions that output arrays, such as SEQUENCE which can also be applied similar to these examples depending on the situation, but I'll focus on ARRAYFORMULA here as it's the most generic and MOST functions can be wrapped in it and otherwise behave as you'd expect.
Here is also a link to an ARRAYFORMULA & MMULT Example Provided by Google (Note that this link will make a copy of the sheet, not let you directly access the example). The first tab is all about matrix multiplication, the second and later tabs have examples using ARRAYFORMULA.
The examples above are pretty limited in scope, so let's expand on those. To illustrate, I will use a basic formula involving 4 columns as an example. Let's say we have data in columns A, B, and C, and we want to do a relatively simple formula between them. Let's assume row 1 is being used as a header row, and your data is from row 2 down, as most people would do. Let's make the formula simple, but a little interesting, by having column D equal to the PREVIOUS value of A plus the product of B and C. Let's also assume we currently have 12 rows of data, but we know we will have data we need to enter in the future. Most of that data will get entered at the end, but sometimes we may need to add data in the middle of the range.
You can follow along with my Publicly Posted Example Sheet Here if you want (this will also create a copy on your drive so you can make changes and follow along). Each example below corresponds to a tab in the Example Sheet.
EXAMPLE: FORMULA ON EVERY ROW
In it's simplest form, the formula in D2 would be = A1 + B2 * C2. Except, of course, we know A1 is a text header and if we include that we'll get an error. It's also commonly understood that absolute references (with $) execute faster in Google sheets, and we don't need relative references on the columns (but rows are necessary to fill), so let's modify cell D2 as follows:
=IF( ISNUMBER($A1), $A1, 0 ) + $B2 * $C2
Then fill down to cell D13 (this is already done in the example).
So now you have your current data... but what if you need to add data?
If you add data to row 14, in columns A, B, and C, you then also have to copy the formula to D14. Easy peazy for this example, but what if you have 30 columns, 5 of them with formulas and you add another 10 entries to the list every day? This becomes very tedious. You can avoid entering it for every row, but filling down the number of rows you need today and save a little time, but it breaks your flow of data entry.
Even worse, what if the entries are in some sort of order (e.g. order of date data was captured) and you get old data that needs to be entered in the middle of the range? You can add at the end and copy, then sort.
Some sheets won't let you sort, or won't sort correctly if you have certain data, so you may need to insert in the middle... let's say between rows 8 and 9. If you did this in an Excel table, and used "insert row" it would automatically populate cell D9 with your formula.
But here, when you add this new row 9 not only is D9 blank and need you to enter the formula, but now the A column reference in cell D10 is pointing to A8 instead of A9 where it should! So you have to recopy / refill your equation to cell D10 as well - and this is easy to miss - you may not know to do it, or forget to do it, and now your formulas are broken.
... Now, to be honest, Excel didn't get this part right, either.
Somehow, it properly fills D9 in with the correct formula but botches
D10 with a reference to A8, but then continues with a correct reference to A10 in D11. Which is almost worse because since D9 was filled and all the other rows are correct, you may not realize you have a problem in D10...
This is basic spreadsheet use and is roughly the same behavior as using Excel WITHOUT Tables (except those instances where it decides to make suggestions for you) - so par for the course here if Excel didn't have the Table or suggestion ability.
Pros:
Simplest formula to implement
Works fine in fixed size sheets or sheets that don't change often
Tried and true, Will always work
Cons:
Have to copy formula to every new row you make
Very tedious for "living documents" that change often
If any formulas cross between rows, the pattern breaks when you insert a row
in between and you have to copy your formula to the row below as
well as your new one
With all the additional required repeated actions, it's very easy to make a mistake
Since the mistake could be in a single cell, finding the mistake after the fact can be difficult
EXAMPLE: CLOSED RANGE ARRAYFORMULA
Google support touts this as the best method. Indeed, if you want your formulas to update automatically when you add data in between and you want the least amount of computation time, then an ARRAYFORMULA with a limited (or "closed") range is the best solution.
To use ARRAYFORMULA, you put the formulas only in your top row of data (in this example, row 2). What makes this example closed range is that we will set it to cover exactly the data we have. So, the formula in D2 would be:
=ARRAYFORMULA( IF( ISNUMBER( $A$1:$A$12 ), $A$1:$A$12, 0 ) + $B$2:$B$13 * $C$2:$C$13 )
Here, we can (and I recommend) use all absolute references as the range we're using doesn't change as the cell row it's calculating changes. When you enter this formula, you will see it automatically populate D3 through D13 with the correct data as well.
If we want to add another row in the middle, it's easy. Taking the previous example, if we add a row between rows 8 and 9, you will see the formula in D2 has changed all the last rows - 12 is now 13, and 13 is now 14. When you enter data into columns A, B, and C in the new row 9, it automatically calculates correctly in D9.
When you look at the data in rows in column D (except D2), however, it shows the number itself in the formula bar - so someone looking at this sheet unaware there is an ARRAYFORMULA in use has no indication that it's an ARRAYFORMULA and overwriting ANY cell that was populated by ARRAYFORMULA will break the formula, give you an error in D2 and leave the rest of the values in the column blank. This is true for all methods using ARRAYFORMULA So, for that reason, I recommend you make your column a protected range!
Alternate: You could name all of your ranges. For example, $A$1:$A$12 could be col_A_prev, $B$2:$B$12 could be col_B, and $C$2:$C$12 could be col_C. Which gives the formula:
=ARRAYFORMULA( IF( ISNUMBER( col_A_prev ), col_A_prev, 0 ) + col_B * col_C )
The behavior would be identical. When you add a row in between, the named ranges will automatically expand to include it. You could also use the same ranges for your column protection to ensure no data is written over.
Note: I do want to give kudos where it is due. Google Sheets handles named ranges WAY better than Excel. When you add or remove rows / columns inside your named range in Google it automatically expands the range - and Google actually allows you to use the named ranges as references in any of the settings (conditional formatting, protection, etc.). While you can enter a named range in Excel for some of these, it will convert it to R/C references which won't change even if your range changes later. If you want to add to the ends or you move rows / columns in your named range - well, they're both still terrible at that
However, if we want to add new data to the end, in row 14 or after, this arrayformula will not automatically update.
Even worse, if you add a row between rows 12 and 13, it breaks the formula - as the references to columns B and C will update, but the references to column A will not - because A only went to row 12. In row 14 you now get the error:
Array arguments to ADD are of different size.
Because you're trying to add an array with 12 elements to an array with 13 elements. Admittedly, this is only a problem if you're referencing other rows which isn't that common across all useful spreadsheets. However, there are many practical reasons to do so, like cumulative sums.
So, either you have to deal with updating your ARRAYFORMULA columns each time you add data to the end (which doesn't make it much better than just copying your formulas to each row) or, you could basically make the last two rows "dummy rows" that you don't care about and add protection to those rows so they can't be edited or a row added between them, with perhaps a note saying "To add new data, insert a row above this line" so other people using it know what they have to do.
Pros:
Relatively simple formula to implement
Fastest Execution time
Will automatically adjust formula to any rows added in the middle
Can manage your ranges as named ranges
Cons:
Have to change the formula if you add any new data to the bottom (which is where you usually add new data) -OR- you have to implement one or more blank rows included in range with protection & reminders to ensure no one adds data to the bottom
Data below ARRAYFORMULA looks like just number entries and could easily confuse people into thinking it's not a formula entry and overwrite it without thinking.
EXAMPLE: OPEN RANGE ARRAYFORMULA
If you're following along in the example sheet, the first thing you'll note is this sheet doesn't do the same thing. It is simply using the CURRENT value in column A, rather than the previous row. This is because you CAN'T reference a previous row with this method (see a couple paragraphs down for why). To compensate, I forced A, B, and C to 0 in the first row and added another row to the bottom.
This is similar to the closed range example in its application of ARRAYFORMULA the difference here, is instead of having a fixed end to the ranges (rows 12 & 13 above), you leave the range open by using just the column letter at the end of the range, which references the last row of the column. So the equation in D2 now looks like this:
=ARRAYFORMULA( IF( ISNUMBER( $A$2:$A ), $A$2:$A, 0 ) + $B$2:$B * $C$2:$C )
The reason you can't reference a previous row's cell is if we used $A$1:$A here, that array would always have one more element than either $B$2:B or $C$2:$C and thus won't be able to add and will result in the error:
Result was not automatically expanded, please insert more rows (1).
Except inserting more rows won't work because the ranges will all expand by 1 also. Again, this is only a problem if you need to reference other rows which isn't common but is useful for things like cumulative sums.
When it comes to adding rows, though, this method is the best. Whether you are adding to the middle or the end of your data, it will automatically update the values in your ARRAYFORMULA columns.
Alternate: Same as with closed ranges, you could name all of your ranges. For example, $A$1:$A could be col_A_prev, $B$2:$B could be col_B, and $C2:$C could be col_C. Which gives the same formula as with closed range:
=ARRAYFORMULA( IF( ISNUMBER( col_A_prev ), col_A_prev, 0 ) + col_B * col_C )
So if you're not referencing previous rows, or if you just add a top "dummy" row like I did in the example, it's all good... easy peazy lemon squeezy, right?
Yes, at least at first. The other problem here is that open ranges are computationally intense for Google Sheets algorithms. As you add more and more rows, especially if you have multiple open range ARRAYFORMULA columns, the sheet calculations get slower and slower and slower. The sheet I was working on that prompted this had 21 columns, 8 of which had ARRAYFORMULA formulas in row 2. At around 200 rows of data (not that much in the world of spreadsheets) it was taking MINUTES to calculate with each and every change I was making. That's simply not useable - I almost went back to copying the formula to each row. (It's possible using named ranges may improve the speed some - I didn't try it on that sheet)
So this solution doesn't really work for big (but not even that big) spreadsheets where you have lots of formulas.
Also, a more minor gripe - you'll notice in the example that every row on the spreadsheet was now populated in column D, even where no data was entered. That's annoying, but not a sheet killer by any means - and you could add an IF statement to the ARRAYFORMULA to just output "" whenever you have no data in one or more data columns.
Pros:
Relatively simple and straight forward formula to implement
"Works" with any number of rows
Automatically includes any rows that are added - on the end or in between
Can manage with named ranges
Cons:
Cannot reference data from previous rows
Extremely slow - computation time goes up with every added row (& every added column with an open reference)
Data below ARRAYFORMULA looks like just number entries and could easily confuse people into thinking it's not a formula entry and overwrite it without thinking.
EXAMPLE: HYBRID ARRAYFORMULA
Are you ready to give up on Google Sheets yet?
Well, there is one more option. It gets complicated and involved, but IMO works better in most situations than any of the above examples.
What I do here is add a cell with a formula for the number of rows in the sheet that have data in a certain column. Let's just say column A for this example. That formula looks like this:
= ARRAYFORMULA( MAX( IF( LEN($A:$A), ROW($A:$A), ) ) )
This, in and of itself, is an open ranged formula. It scans everything in column A and returns the last row that has SOMETHING in it. But it's one single formula in one cell reporting 1 value - no other cells get populated from it. It's relatively computationally intense for this one cell, but it's just one cell in the entire sheet.
Then, to make sure that any changes you make (adding / removing rows or columns) do not affect any references to that cell, name it. In the example provided, this is named last_example_row.
I also strongly recommend that you add protection to last_example_row so it's not accidentally changed. Extra tip: you can actually set both sets of permissions: "Only You can edit" and "show a warning when editing" so even if you try to edit it accidentally it will give you the chance to cancel the edit.
Since it's not a piece of data you need visually, hiding it is also a good idea (I left it unhid in the example so you can easily see the formula)
Now, in order to use the value in last_example_row as part of our ranges, we have to use the INDIRECT function. We replace every open-ended instance in the previous example with a specific INDIRECT call.
For calls to the same row, for example, we replace with a pattern like this:
$B$2:$B is replaced with $B$2:INDIRECT( "$B$" & last_example_row )
so it ends on the last used row.
For calls to the previous row, we replace with a pattern like this:
$A$1:$A is replaced with $A$1:INDIRECT( "$B$" & ( last_example_row - 1 ) )
so it ends 1 row before the last used row.
So the final equation becomes this monstrosity:
=ARRAYFORMULA( IF( ISNUMBER( $A$1:INDIRECT( "$A$" & ( last_example_row - 1 ) ) ), $A$1:INDIRECT( "$A$" & ( last_example_row - 1 ) ), 0 ) + $B2:INDIRECT( "$B$" & last_example_row ) * $C2:INDIRECT( "$C$" & last_example_row ) )
So it's a closed range reference that points to a single open range calculation, and it works. Whether you add data in the middle or to the end, it automatically calculates your column for you - and it only populates rows where your data is also populated.
Since it only does the open range calculation ONCE, then uses that value in all remaining closed range calculations, this is much, much faster than the open range example above. It IS slower calculating than the first two examples, however - but I haven't yet hit the point in my real sheets where the delay has made it unusable (stay tuned as I add more data to my sheets over time). If anyone reading this has hit that point with this method, please let me know how many columns & rows you got to, including how many of the columns used an ARRAYFORMULA like this.
Unfortunately, however, since this method requires an INDIRECT call, you cannot use named ranges to accomplish this.
Pros:
Most flexible option
"Works" with any number of rows
Automatically includes any rows that are added - on the end or in between
Much Faster than completely open references
Cons:
Formulas are complex, hard-to-follow, and easy to make a mistake while entering
Slower than closed references - computation still time goes up with every added row and every added column with these "hybrid" references
Data below ARRAYFORMULA looks like just number entries and could easily confuse people into thinking it's not a formula entry and overwrite it without thinking.
Cannot manage with named ranges
Epilogue
Maybe (hopefully) someday Google will add a feature that will keep track of your formulas and execute them in a speedy way and this post will be obsolete. Until then, I hope this post helps someone out there.
Additional Note
Using any of the ARRAYFORMULA methods above can break sorting. If you add filters, and the sort by A->Z or Z->A on a particular column and row 2 is no longer row 2 - then your ARRAYFORMULA gets moved to whatever row it gets sorted to - and then only applies from that row down. Rows above it will be blank in all your ARRAYFORMULA columns. This is very disappointing to me. One way around it (that I don't like) is you can make row 2 a "dummy" row where whatever columns you may sort by have values that will always make it the top row. That's a pretty ugly solution, though.
You can make it less "ugly" by hiding row 2. Then columns will sort fine and you won't see any of the dummy data ("dummy" data may not even be necessary as the hidden row shouldn't sort with the rest). The caveat here is if you share it with multiple users - they won't even see there is a formula being used, it looks like all manual entries - and if one gets overwritten, it will break the ARRAYFORMULA. So, I would recommended protecting the ARRAYFORMULA columns, as well.

Getting number and off setting numbers from array in Excel

I have array of numbers in a single column like this:
I want only that numbers for which corresponding negative numbers exist. If number exist 2 times, but negative number exist only one time, then I wanted to retain one positive and one negative number. Similarly, if number exists 3 times, and negative number appears only two times, then I want 2 set of numbers including positive and negative. In this case, I wanted to get output:
5 2 -2 -5
Orders of numbers are not relevant for me. Please do not use VBA. You can create multiple column and apply filter at the end.
Thank you for the response, but I wanted to get the data in column next to the values. Like:
5
2
-2
-5
Please help.
Here's another Office 365 solution:
Name the data range DATA
Put this formula anywhere: =CONCAT(REPT(-ROW(A1:A100)&" "&ROW(A1:A100)&" ",COUNTIF(DATA,"="&ROW(A1:A100)*IF(COUNTIF(DATA,"="&-ROW(A1:A100))<COUNTIF(DATA,"="&ROW(A1:A100)),-1,1))))
That will output the pairs into one cell.
Here's a slightly modified Step 2, which excludes duplicates: =CONCAT(IF((COUNTIF(DATA,"="&-ROW(A1:A100))>0)*(COUNTIF(DATA,"="&ROW(A1:A100))>0),-ROW(A1:A100)&" "&ROW(A1:A100)&" ",""))
Looks like this:
The data doesn't need to be sorted. Both methods work up to 100, but you can easily expand that by changing A100 to A1000 or whatever you need.
Use the vlookup formula to identify the rows, and you can use the Filter & Unique formula to get the list, or a pivot table.
First, immediately next to your data use the formula:
=vlookup(A1*-1,$A$1:$A$1,1,0)
For non-365:
This will produce an error for each instance that doesn't have a match. You can filter at this point to get your list from the existing table. You can also create a pivot table under the Data tab of your ribbon and inserting a pivot table. Filter the #N/A from there to get an exclusive list without hidden rows.
For 365:
You can use the following combination of formulas to get the exclusive list as well.
=UNIQUE(FILTER(B1:B8,ISNUMBER(B1:B8)),0,0) or =UNIQUE(FILTER($B$1:$B$8,ISNUMBER($B$1:$B$8)),0,0) should yield the same results
As ScottCraner mentioned, you can circumvent the helper column in 365 by modifying the formula a bit more:
=UNIQUE(FILTER(A1:A8,ISNUMBER(MATCH(-A1:A8,A1:A8,0)),"")
The Match here is doing something similar to the Vlookup, but housing that logic within the formula, so it's a cleaner solution in my opinion.
Using your data the result was { -5,-2,2,5 }
These are spill formulas so you only need to put it in one spot and it will expand the formula over the adjacent cells below where it's entered for however many cells needed to list all the unique numbers that occur. It takes into account the negatives and so on. This may be a 365 formula, so if you're on another version of excel it may not work.
Edit: Adjusted the instructions to fully address the question.

excel Sum every other column up to certain month

I have a Simple spreadsheet with 2 rows:
ActualJAN | BudgetJAN | ActualFEB | BudgetFEB | ActualMAR | BudgetMAR ....
100 200 300 400 500 600 ....
I'd like to sum ONLY the Budget columns up to the current month (Month(Today()).
Same for the Actual columns.
So if we're currently in February,
Budget to date would be: 600=200+400
Actual to date would be: 400=100+300
I just can't seem to get there, at least simply and elegantly.
This is a non array formula that performs array like operations. As such large range references should be avoided or you will experience a slow down or potential crash of your system. For a small defined range works great so long as the formula is not repeated too many times either.
Additionally TODAY() is a volitile function which means the formula will recalculate whenever anything in the spreadsheet changes, not just when something related to the formula changes.
This formula is generalized a bit so your data can be located anywhere on your sheet and does not require rearrangement of your data.
To get your actual sum use the following:
=SUMPRODUCT($C$4:$H$4*(COLUMN($C$4:$H$4)-COLUMN($C$4)+1<=MONTH(TODAY())*2)*(LEFT($C$3:$H$3)="A"))
To get your Budget sum use the following:
=SUMPRODUCT($C$4:$H$4*(COLUMN($C$4:$H$4)-COLUMN($C$4)+1<=MONTH(TODAY())*2)*(LEFT($C$3:$H$3)="B"))
Change C4:H4 to suit your number range. ChangeC3:H3 to suit your column title range. Change C4 to be the first cell of your number range.
Caveat: Assumes maximum 12 months starting at January
Proof of concept:
I would recommend structuring your data differently. It would be an easier task if you arrayed everything vertically and divided your data into three columns. The first would be Category, which would be populated with either "Budget" or "Actual." The next column would be Month. After that, of course, you have the Value column. Then, use a basic SUMIF, like "=SUMIF(A1:A6,"Budget",C1:C6)." A1:A6 is the range Excel will scan for the desired variable. In this case, that variable is "Budget." Then, C1:C6 is the value that corresponds to a "Budget" month. That formula will give you the answer you want as long as you expand the SUMIF formula to include the full range of values, e.g., "SUMIF(A1:A317,"Budget",C1:C317)."
So I think I understand what you're trying to do, I cannot make the entire formula without the rest of the spreadsheet but this is working currently:
For the Actual:
=IF(MONTH(TODAY())=1,A2,IF(MONTH(TODAY())=2,A2+C2,IF(MONTH(TODAY())=3,A2+C2+E2,"")))
For the Budget:
=IF(MONTH(TODAY())=1,B2,IF(MONTH(TODAY())=2,B2+D2,IF(MONTH(TODAY())=3,B2+D2+F2,"")))
Here is the spreadsheet I created to test:
If you give me the rest of the data I can complete the formula, basically all you would need to do is add more months to the formula and change the amounts it adds.
I am sure there is probably a more efficient way to accomplish this but this way works.
I suggest a hidden row to control your dates. Say, January is in column C, enter [C1] =1, [D1] =C1, [E1] =C1+1, [F1] =E1. Select E1:F1 and copy to the right until December. Hide row 1.
In row 2 use these two formulas.
[C2] ="Actual" & UPPER(TEXT("1/" & C$1,"mmm"))
[D2] ="Budget" & UPPER(TEXT("1/" & D$1,"mmm"))
Select C2:D2 and copy to the right until December. This exercise isn't required because the resulting display is exactly what you already have. But producing this result with the help of formulas ensures freedom from error, and it is faster. As an added bonus you get a visual check of what's in the hidden row.
Now you can use this formula to extract totals from row 3 where you have your values.
=SUMIFS($C3:$Z3,$C$2:$Z$2,"Budget*",$C$1:$Z$1,"<="&MONTH(TODAY()))
Change "Budget" to "Actual" and the same formula will extract the actual amounts.

Inconsistent Excel VLOOKUP

I have an odd problem with some formulas in my Excel sheet for fantasy football:
In one table, I have a list of the picks and players drafted in one year. The columns are as follows: CO = Player name, CP = Year, CQ = Round, CR = Pick, CS = Owner.
Column CO is hand-entered with names, CP is hand-entered with the year 2011, and CQ is hand-entered with the draft round (the first ten are round 1, the second ten are round 2, etc).
Column CR is a formula that calculates the pick number based on the round number and the row it's in. The formula in cell CR2 looks like this: "=CQ2+MOD(ROW(CR2)-2,10)/100+0.01" and evaluates to "1.01". CR3's formula would evaluate to "1.02", CR4 would evaluate to "1.03", etc.
EDIT: Here's a picture of the top 15 rows of this sheet: picks sheet here
On another sheet, I have a 5x10 grid of VLOOKUP formulas where I try to list which owner has which picks. The VLOOKUP formula for each of the cells in this grid is as follows: "=VLOOKUP(1.01,Picks2011[[Pick]:[Owner]],2,FALSE)", where "1.01" is the name of the pick from column CR, "Picks2011" is the name of the table in the previous sheet, and "[[Pick]:[Owner]]" are the columns in the table "Picks2011". This example formula correctly outputs the name of the owner who had pick 1.01 in 2011.
EDIT: Here's a picture of the grid with the failing cells: grid showing the errors
The problem is that certain cells in this sheet are giving me an "#N/A" for no particular reason. For example, pick 2.01 outputs correctly, but pick 2.02 outputs #N/A, and pick 2.03 outputs correctly again. There doesn't seem to be any kind of a pattern to the errors. I've tried deleting both tables and recreating them from scratch, and I can't seem to figure out what's wrong with them.
Travis... I noticed that the VLOOKUP formula is pointing to a grid formatted as a table, which I love since it makes it easier than having to deal with specifying and anchoring ranges.. however, the fact that the N/A issue you are running into appears to happen every other row, makes me wonder if the formatting on those culprit rows is different than the formatting on those rows returning the values you'd expect. Maybe check that, and as a way of troubleshooting try copying data from the working rows into the failing rows to see what value your vlookup returns.. worth the shot.
Take a look at using an INDEX(MATCH) construct instead of VLOOKUP.
Unfortunately VLOOKUP behaves pretty unpredictably if you're not working with just two columns of unique strings.
I wrote an answer here ( Excel - How do programmatically convert 'number stored as Text' to Number? ) which may be just what you're looking for!
INDEX ( <return array> , MATCH ( <lookup value> , <lookup array> , 0) )

Sumproduct or Countif on a 2D matrix

I'm working on data from a population of people with allergies. Each person has a unique ExceptionID, and each allergen has a unique AllergenID (451 in total).
I have a data table with 2 columns (ExceptionID and AllergenID), where each person's allergies are listed row by row. This means that the ExceptionID column has repeated values for people with multiple allergies, and the AllergenID column has repeated values for the different people who have that allergy.
I am trying to count how many times each pair of allergies is present in this population (e.g. Allergen#107 & Allergen#108, Allergen#107 & Allergen#109,etc). To keep it simple I've created a matrix of 451 rows X 451 columns, representing every pair (twice actually because A/B and B/A are equivalent).
I somehow need to use the row name (allergenID) to lookup the ExceptionID in my data table, and count the cases where that matches the ExceptionIDs from the column name (also AllergenID). I have no problem using Vlookup or Index/Match, but I'm struggling with the correct combination of a lookup and Sumproduct or Countif formula.
Any help is greatly appreciated!

PS I'm using Excel 2016 if that changes anything.
-=UPDATE=-
So the methods suggested by Dirk and MacroMarc both worked, though I couldn't apply the latter to my full data set (17,000+ rows) because it was taking a long time.
I've since decided to turn this into a VBA macro because we now want to see the counts of triplets instead of pairs.
With the 2 columns you start with, it is as good as impossible... You would need to check every ExceptionID to have 2 different specific AllergenID. Better use a helper-table with ExceptionID as rows and AllergenID as columns (or the opposite... whatever you like). The helper table needs a formula like:
=COUNTIFS($A:$A,$D2,$B:$B,E$1)
Which then can be auto-filled. (The ranges are from my example, you need to change them to your needs).
With this helper-matrix you can easily go for your bigger matrix like this:
=COUNTIFS(E:E,1,INDEX($E:$G,,MATCH($I2,$E$1:$G$1,0)),1)
Again, you can auto-fill with this formula, but you need to change it, so it fits your needs.
Because the columns have the same ID2 (would be your AllergenID), there is no need to lookup them because E:E changes automatically with the auto-fill.
Most important part of the formulas are the $ which should not be messed up, or you can not auto-fill it.
Picture of my self-made example (formulas are from the upper left cell in each table):
If you still have any questions, just ask :)
It can be done straight from your original set-up with array formulas:
Please note that array formulas MUST be entered with Ctrl-Shift-Enter, before copying across and down:
In the example pic, I have NAMED the data ranges $A$2:$A$21 as 'People' and $B$2:$B$21 as 'Allergens' to make it a nicer set-up. You can see in the formula bar how that looks as a formula. However you could use the standard references like this in your first matrix cell:
EDIT: silly me, N function is not needed to turn the booleans into 1's and 0's, since multiplying booleans will do the trick. Below formula works...
SUM(IF(MATCH($A$2:$A$21,$A$2:$A$21,0)=ROW($A$2:$A$21)-1, NOT(ISERROR(MATCH($A$2:$A$21&$E2,$A$2:$A$21&$B$2:$B$21,0)))*NOT(ISERROR(MATCH($A$2:$A$21&F$1, $A$2:$A$21&$B$2:$B$21,0))), 0))
Then copy from F2 across and down. It can be perhaps improved in technique with sumproduct or whatever, but it's just a rough example of the technique....
