I feel like I'm missing something here but can't find out what. I'm creating a planning template. I want a separate table in which the user can put the deadline name with the deadline week.
In my planning overview I want these deadlines to appear. To do this, I tried an approach with IF()-statements. Although this works well, it doesn't deal with a new deadline that is added later on in the project.
I could brute force this and create 30 IF()-statements so there's space for 30 deadlines (which is more than enough) but I have a feeling this can be done in a much smoother way. Do you have any suggestions for this?
You can use INDEX/MATCH:
=IFERROR(INDEX($A:$A;MATCH(E2;$B:$B;0));"")
looks like you have not used the function vlookup before.
Vlookup is one of essential functions in excel and learning & starting use of it will definitely make you a better excel user and save you lots of time later on.
You can solve your puzzle via vlookup as described below:
Swap the columns "name" & "week". Week will be in col A, Concept in col B.
Write this formula to cell E1 and then you can paste it to F1 to N1:
=IFERROR(VLOOKUP(E$2;$A$2:$B$50;2;FALSE);"")

This may be impossible, but I am trying to create a baseball fielding lineup generator that has a few constraints provided by the league (ie. must play twice in infield, twice in outfield, no repeats at any position). I think this would be fairly simple task using any programming language, but I am designing this for my 70yo uncle and he can basically only use excel with no macros. So I can't brute force my way through the problem and I don't think I understand the mathematics behind the problem well enough to even know if there is a excel formulaic solution.
At it's essence it's a Sudoku creator and solver with no repeats in the rows or columns. I have an ok solution for the infield/outfield part via ranking the individuals by position.
Recursively calculating with F9 is ok for the solution since this is just a change in the options menu, but the last time I sent him a macro his university MS account wouldn't let him run it or change the settings.
Well, I have plenty of other info and have gotten close to solutions using huge nested IFs, but this relatively brute force method seems to be pretty dumb and is not giving great solutions.
Thanks for any help!
Well if your uncle has access to Excel 365 (sounds like a big if), you could use sorting to remove players already used in a given row or column, e.g. like this copied down and across from B2:
=LET(range,$L$2:$L$27,
choice,IF(COUNTIF(B$1:B1,range)+COUNTIF($A2:A2,range)=0,range),
count,COUNT(choice),
sort,SORT(choice),
INDEX(sort,RANDBETWEEN(1,count)))
If the players were given names instead of numbers, you could try
=LET(range,$L$2:$L$27,
choice,IF(COUNTIF(B$1:B1,range)+COUNTIF($A2:A2,range)=0,range),
count,SUM(--ISTEXT(choice)),
sort,SORT(choice),
INDEX(sort,RANDBETWEEN(1,count)))
I would like to create a report that look like this picture below.
My data has around 500,000 cells (it will continue to grow larger)
Right now, I'm using countifs function from excel but it takes a very long time to calculate. (cannot turnoff automatic calculate)
The main value is collected as date and the range of date is about 3 years, so I have to put a lot of formula to cover all range of value.
result
The picture below is the datasource the top one cannot be changed. , while the bottom is the one I created by myself (can change). I use weeknum to change date to week number.
data
Are there any better formula or any ways to make this file faster? Every kinds of suggestions are welcome!
I was thinking about using Pivot Table, but I don't know how to make pivot table from this kind of datasource.
PS. VBA is the last option.

I will post this answer with the disclaimer that it is entirely dependent on the size of the data set. That turning on and off the auto calculate is the best way, but your question doesn't let me do that, so keep reading.
Your question made me curious, so I gave it a try and timed it. I essentially set up two columns of over 100,000 rand numbers choosing from 1-1000 and then tried to do a countif on the two columns if they were equal. I made a macro that I can run that turns off the autocalculate, inserts the start time, calculates, and then inserts the finish time. I highlighted in yellow the time difference.
First I tried your way, two criteria, countifs:
Then I tried to combine (concatenate) the two columns to see if I could make it easier by only having one countif criteria and data set. It doesn't. see result below:
Finally, realizing what was going on. I decided to make the criteria only match the FIRST value in the number to look for. I was essentially reducing the number of characters to check per cell. This had a positive result. See below:
Therefore my suggestion is to limit the length of the words you are comparing in anyway possible. You are mostly looking at dates, so you might have to get creative, but this seems to be the best way possible without going to manual calculation.
I have worked with Excel sheets of a similar size. Especially if you are using the data on a regular basis, I would heartily recommend switching to a proper database SQL based, Access, or whatever fits your purpose. I does wonders for the speed and also you won't run into the size limits of Excel. :-)
You can import the data you have now fairly easy.
I am happy as a clam with my postgresql db.
I'm working on this new project and I'm trying to set up a dynamic spreadsheet where once one process is complete another will start. To illustrate,
I have a series of payments paying off a mortgage, once the mortgage process is complete (principal remaining is zero) I need the series of payments to start paying off another loan. I'm having a problem setting up the spreadsheet to start one processes when another is done. I think some sort of if function is probably going to come in handy, if anyone has any ideas it would be much appreciated.
Thanks!
What you're trying to do goes a little against the grain of Excel, but you can mimic the functionality you want pretty easily. It would take a second header row.
You don't have a ton of specifics in the prompt, so I'm going to use some general examples.
So, assuming you have your first process information in Column B, and your third process information in Column C, you would place a formula in B2 that determines whether the B process has completed, like:
=IF(SUM(B3:B400)>=5000,"Done","Not Done")
Then, your formulas from C3 to C(whatever) would involve:
=IF($B$2="Done",[Your_Stuff_Here],"")
I'm trying to make a spreadsheet for some calendars that I'm selling. I have a pricing scheme which depends on how many calendars a customer buys. I want to be able to keep track of sales, but I don't want to have to input the price per unit for each sale. I set up an IF statement that seems to work except for the last variable. Here's a screenshot:
As you can see, it works all the way to the last one. After the number reaches 11, the price per unit should drop to 6, but it doesn't! I know it must be a simple fix, but I don't know much about IF statement, so I'm stuck. Please help!
If you set up your price table similar to my set-up below, you can use a VLOOKUP formula to make it more flexible.
The formula in H10 is:
=VLOOKUP(G10,$B$1:$C$5,2,TRUE)
Enter and drag down.
The benefit of this approach is that you can change the lower bound count on the left and you'll get an adjustment without having to update the formula. Try changing the 2 in Count to 3 and you'll see the adjustments right away.
An added benefit is you can add some more values to the table for further pricing brackets.
If you must use an IF statement, try:
=IF(G10=1,9,IF(G10<=5,8,IF(AND(G10>5, G10<11),7,IF(G10>=11,6,IF(G10="","")))))
The problem with yours is it will never read the if(G10>=11 part because it has already evaluated if(G10>5
If it should have no output when G10 is blank, use the following variant:
=IF(ISBLANK(G10),"",IF(G10=1,9,IF(G10<=5,8,IF(AND(G10>5, G10<11),7,IF(G10>=11,6,IF(G10="",""))))))
I agree with #Nanashi that putting the price thresholds in a separate table and using vlookup is a better solution. That would make it possible to change the price points without having to edit multiple formulae.
But to just get your formula working, try this: =if(g10="","",if(g10=1,9,if(g1<=6,8,if(g10<=10,7,6))))
Notice that:
You don't need (and probably don't want) quotes around your numeric
values
The order of tests is important. In your original, the test for g10>=11 is never reached because it is in the else part of the g10>5 function.
A properly constructed table of quantities and pricing coupled with a VLOOKUP formula would be the best way to go and eases future pricing changes. But for the sake of diversity, your straightforward pricing structure could also be handled by the following:
=(6+(G10<11)+(G10<6)+(G10<2))*(G10>0)
In the formula, "G10>5" should be "G10<=10". Otherwise, when it gets to 11, it still meets the G10>5 criteria.
Ok so, twice a month I receive a large file of about 100 rows, which contains 4 columns:
Building name - value - county - state
I´ve to complete 2 other columns based on a master list that have thousands of entries.
I want to produce something very similar to this fabulous add-in (http://www.microsoft.com/en-us/download/details.aspx?id=15011), but a bit simpler and that I could use at work without problems.
What I need to do is the following:
In order to match my input with the master file, I know the county and state must match, but then, the building names can change a bit in each file for the same building (ie "John Miller #34" can be "Miller, John 34 A"), and that the values may vary but not too much.
Based on that, I want to bring from the master to my file, all the entries that may match each of my rows, filtering by County and State first, and then by similarity in name and value.
Could you please share your thoughts on how you´d approach this?
I know this is not a simple thing, but anything may help!
You could also use wildcards to try and match on the primary identifier within the name. from your example, that might be "Miller", for example.
Unfortunately for you, the vlookup "fuzzy logic" is nowhere near reliable for your purpose (see the comment on my answer below for details), and you won't have any indicator as to whether the returned result is accurate or not.
It's possible to get 100% of what you want through some heavy coding in a user-defined function, but this is probably well beyond your comfort zone.
A clunky solution, although somewhat easy to explain and adopt, is to create an "identity column" for every unique scenario that can occur. So, for example:
Then you can import your master sheet and add the same identity column to the left, and perform your vlookup. When a new configuration is added you can just add that to the master list and it will populate in your imported file in future instances.
That said, if you are interested in learning, there have been many people who have walked in your shows and felt your pain. You may want to indulge in this:

Because what you are truly requesting is an algorithm. It's not a simple thing, but it's very possible. And if you take the time to learn you not only solve your immediate problem, but make yourself marketable as an Excel wiz. Good luck!
