I need to create an analysis for work in Excel, one of the things that have been asked is that I include a chart, this chart needs to show data grouped by a state given to it and a number of days passed since the date it was created.
I need to count how many of these bits of data there are that are older than 1 day, older than 2 days and so on, I have been looking at some way to combine COUNTIF/COUNTIFS and TODAY()-Date named in cell, this hasn't been fruitful, I am aware that I would just do the TODAY() bit in some seperate cells and work with the data from the but I would prefer a way to do it all in one, if there is some way to do such a thing in one formula it would be great, if not I'll just have to tell my boss no can do.
Thanks in advance for any help given, even if it is telling me it's not possible.
=CountIfs(state, inputState, date, "<"&Today()-1, date, ">="&Today()-2)
That will give you all items holding state from the day before yesterday.
state and date are from your data. Replace with column references or (better) named range names.
Use < and >=, or <= and >, when slicing data by date (or any numeric amount). Using < and > or <= and >= forces you to think hard about gaps or overlap and that's no fun.
Another method would be to use SUMPRODUCT to count the number of occurrences:
=SUMPRODUCT(--(A1:A20>=TODAY()-2))
The number 2 can be increased or decreased to vary the length of time from TODAY(). The >= symbols can also be changed based on whether you would like to count the number of dates before or after TODAY()-2.

oversimplified i have two columns: Date and Text; I want to check my current amount of vacation days based on the first date in row 2, so i came up with the following formula:
="Available vacation days: "&YEARFRAC(A2;TODAY())*12*(25/12)
I calculate the fraction of the year based on the first date and todays date, multiply it by 12 to get months and multiply it again by the total amount of vacation days in my contract per month. Now i got another formula to collect me all cells in column B containing "Vacation", pretty straight forward:
=COUNTIF(B:B;"Vacation")
Now the interesting part - i got the formula who gives me a boolean if a datetime matches the 24th or 31st of december:
=AND(OR(DAY(A53)=24;DAY(A53)=31);MONTH(A53)=12)
I want to count vacation days happening on a 24th or 31st of december as a half-vacation day (0.5), and otherwise fully (as a 1). Then i want to combine my first statement with this result and subtract the used vacation days. I read about VLOOKUP and XLOOKUP but am unsure if this fits this purpose. I want to avoid having an extra column with my boolean returns and rather have this one cell giving me all the information combined.
Without introducing another column, and using DAY and MONTH
It's nearly impossible, and just unnecessarily so...
Please reconsider this, what will happen if you want to add 4th of July as a holiday?
Your formula =AND(OR(DAY(A53)=24;DAY(A53)=31);MONTH(A53)=12) only works for 1 row at a time. So, we can't ever use it with a list, because you will get the whole list as a result every single time. You can't divide them into smaller lists and join them together, there is no such functionality without VBA.
In the future, do not set arbitrary constraints like "no additional columns", you can hide them if you don't like them. And if you don't need them, remove unnecessary rows like non-vacation rows. They are irrelevant, so why not separate the two.
Just to prove my point, here's the solution you wanted:
Solution
=COUNTIFS(B2:B9;"Vacation") - (COUNT(IFERROR(FILTER(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12);DAY(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12))=31);0))+(COUNT(IFERROR(FILTER(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12);DAY(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12))=24);0))))*0,5
It works, but it's a pain to read, use and maintain.
A2:A9 refers to the dates column
B2:B9 refers to the text column
So in the future, the last thing you want to do is set arbitrary constraints. Furthermore, why use functions like MONTH and DAY when we can just read the text? That way you could even create a table of holidays to search for instead. That will be no fun task with this setup. (Oh, and if it's because of the year, just strip it away from the text when you want to know only the month and day.
Best of luck!
I am trying to get the averages of a column that meet certain criteria into a single cell.
The following formula works: =AVERAGEIFS(tblData[Sys],tblData[Time],">=12:00 PM",tblData[Time],"<6:00 PM") but when I adjust the time values to: =AVERAGEIFS(tblData[Sys],tblData[Time],">=6:00 PM",tblData[Time],"<4:00 AM") I get an error. I'm guessing it's because the time range goes into the next day.
Is there a better function to use or a workaround?
This formula seems to work for you scenario. It checks for the possibility that the end time is before the start time (but on the next day) and changes the logic accordingly:
=AVERAGE(
IF(
IF(tmStart>=tmEnd,
(tblData[Time]>=tmStart)+(tblData[Time]<=tmEnd),
(tblData[Time]>=tmStart)*(tblData[Time]<=tmEnd))
=1,tblData[Sys],""))
It's important to understand this function does, and the underlying intentions are - I elaborate in the what follows, proffer a workable solution, provide a reconciliation, as well as a link to the workbook with screenshot below.
You will need to specify # days spanned - even the scenario that 'worked' for you (i.e.. =AVERAGEIFS(tblData[Sys],tblData[Time],">=12:00 PM",tblData[Time],"<6:00 PM") could, in theory, span 2 (or more) days. The fact that this 'works' (doesn't return #DIV/0!) is that the 'intersection' of conditions is an non-empty set (i.e. {12pm-5pm}).
As I say, if this was intended to be ">=12:00" from day 1 through to "<6pm" the following, there is no way of determining whether this is indeed the case by simply 'comparing the times' (e.g. 12pmvs 6pm).
Screenshot/here refer::
=IF($I$5="Y",(SUM(1*($C$5:$C$28*(($D$5:$D$28>=$J$3)+1*($D$5:$D$28<$K$3)))))/SUM((($D$5:$D$28>=$J$3)+1*($D$5:$D$28<$K$3))),IFERROR(AVERAGEIFS(C5:C28,D5:D28,">="&J3,D5:D28,"<"&K3),"times don't intersect! "))
where: I5 = 'Y' or 'N' (i.e. multiple days'). When scenario B is selected, with multiple days = 'Y', outcome = 12.9 which reconciles to a manual calculation.
I have the following excel result:
I want to group the above result in groups based on sessions i.e. if the time gap between two successive timestamps is greater than 5 minutes, it must be a new row.
For example :
I need some formula to achieve this. As I'm fairly new to Excel this is causing to be a major headache for me. Please help me, if anyone knows how to do it or at least point me in a direction.
Thanks a ton !!!
Judging by your screenshot, it appears your timestamps are actually text values. Text by default is usually left aligned where as numbers are right aligned. You seem to have a space at the end of your time stamp suggesting that it is probably left aligned and therefore text. You can test it with the following formula which will return TRUE if its text.
=ISTEXT(P2)
where P2 is one of your time stamps.
CONVERT TIMESTAMPS TO TIME
There are a variety of ways to do this. Some will depend on system settings. Take a look at the following functions as each might be useable depending on your system. The first two are a guarantee, the last two are more dependent on system settings.
DATE
TIME
DATEVALUE
TIMEVALUE
Something important to remember here is that in excel dates are integers counting the days since 1900/01/01 with that date being 1. Time is stored as a decimal and represents fraction/percentage of a day. 24:00:00 is not a valid time in excel though some functions may work with it.
So in order to convert your time stamp in P2 I used the following formula to pull out the date:
=DATE(LEFT(P2,4),MID(P2,FIND("-",P2)+1,2),MID(P2,FIND(" ",P2)-2,2))
Basically it goes into the text and strips out the individual numbers for Year, Month and Day.
To pull out the time, I could have done the same procedure but elected to demonstrate the TIMEVALUE method which is a little more robust than DATEVALUE and not a subjective to system settings as much. With the following formula I stripped out the whole time code (MINUS"UTC"):
=TIMEVALUE(TRIM(MID(P2,FIND(" ",P2)+1,FIND("UTC",P2)-FIND(" ",P2)-1)))
I also made an assumption that you are not mixing and matching UTC with other time zones which means it can be ignored. Now to get DATE and TIME all in one cell, you just need to add the two formulas together to get:
=DATE(LEFT(P2,4),MID(P2,FIND("-",P2)+1,2),MID(P2,FIND(" ",P2)-2,2))+TIMEVALUE(TRIM(MID(P2,FIND(" ",P2)+1,FIND("UTC",P2)-FIND(" ",P2)-1)))
In the example at the end, I placed that formula in Q2 and copied down
DELTA TIME
Since you want to break your groups out based on a time difference between individual entries, I used a helper column to store the time difference. In my example at the end I stored this difference in Column S. The first entry is blank as there is no time before it. I used the following formula in S3 and copied it downward.
=Q3-Q2
I applied the custom formatting of [h]:mm:ss to the cell to get it to display as shown.
FIND GROUP BREAK POINTS
In my example I am using helper column T to hold breakpoint flags. At a minimum, you will have two break points. Your first time entry and your last time entry. To make like simple I simply hard coded my first breakpoint flag in T2 as 1. Stating in T3, Three checks need to be made. If any of them are TRUE then the next flag needs to be added with a value increase by one. the three checks are:
Is this the last entry
Is the next time delta greater than 5 minutes (means end of a group)
Is this time delta greater than 5 minutes (means start of a group)
Based on those three checks I placed the following formula in T3 and copied down:
=IF(OR(S4="",S4>TIME(0,5,0),S3>TIME(0,5,0)),MAX($T$2:T2)+1,"")
Note the $ on the first part of the range for the MAX function. This will lock the start of the range while the formula gets copied down while the end of the range increases accordingly.
Also the row after the last time entry must be blank. IF it is not blank and has a set value in it, change the S4="" to S4="set value".
GENERATE TABLE
There are multiple ways to reference the flags and pull the corresponding times. a couple of formulas you can look into are:
INDEX / MATCH
LOOKUP
In this example I elected to use LOOKUP though I believe INDEX and MATCH are more appropriate and robust. For starters we want to generate a list of ODD number and EVEN numbers. These represent the start and end of the groups and correspond to the flags set in column T. One way to generate ODD and EVEN numbers as you copy down is:
=ROW(A1)*2-1 (ODD)
=ROW(A1)*2 (EVEN)
The next step is to find the generated number in Column T and then pull its corresponding timestamp in Column Q. I did this with the following formula in V2 and copied down.
=LOOKUP(ROW(A1)*2-1,T:T,Q:Q)
And in W2
=LOOKUP(ROW(A1)*2,T:T,Q:Q)
Please have a look at the picture I attached, it'll make understanding my problem easier because it's hard to describe.
In the first table, I have capacity data for a product. The capacity changes by the date indicated in the column, i.e. from July 2017 the capacity would be 56, from December 2018 78, and from October 2019 99. The reason why I don't write down the capacity for every month is that I want to save columns.
In the second table, I have every month. I want to reference the correct capacity for each month, e.g. it would be 56 for every month until December 2018.
I have been considering an =INDEX function, but it seems to complex for that. Is there a way to reference like this without using VBA? Would the VBA solution be simple? Or am I forced to write a column for every month's capacity in the first table? Thank you!

You can simply use several IF statements to compare the month in your column with the months given in your first table, and put the value of the correponding month.
Let's admit your first row is 1 and first column is A, it should give something like:
= IF(D7>=$F$2; $F$3; IF(D7 >= $E$2; $E$3; IF(D7 >= $D$2; $D$3; "")))
I dont see you columns and rows so i hope you will change them correctly on this formula:
=HLOOKUP(C111,$C$106:$P$107,2,TRUE)
C111 is the cell above your red row.
$C$106:$P$107 is the tableof capacities, i know it is bigger then the current one so you see you can add more columns.
2 is the row number from the capacity table.
true is becouse you dont want it to be the exact value it will take the previews in hte order of items
Both previous answers work perfectly, but I would go this way-
You don't actually need an if to find the previous capacity. you can simply use the approximate match (similar to the hlookup answer) in an index formula
=+INDEX($B$4:$E$5,MATCH($B$9,$B$4:$B$5,0),MATCH(C9,$B$4:$E$4,1))
The product $B$9 matches exact (0), but the date C9 is bigger than or equal (1).
$B$4:$E$5 is the source of capacity and
C9:AF9 the date timeline
Final advantage would be that you can have several products to index, not only a single one.
Could you please try the below formula and provide feedback please?
=IF(AND(D8>=D2,D8<E2),"56",IF(AND(D8>=E2,D8<F2),"78",IF(D8>=F2,"99")))
I have a gate keeping report with a number of entry/exit times for an employee over a 24hr period.
I need another formula to go into I40 which is the difference between the first entry time - last entry time for each employee eg. I40 = F50 - D40.
Dont worry about the formula regarding the subtraction of dates as I have this. I really just need the formula that will allow me to get the Last Exit time cell and the First Entry time cell for each employee.
The best way is to always store datetime values (ie, 2018-05-24 13:454) instead of just the times. You could still display it as a time by changing the cell's formatting to a time format.
Shortcut to Number Formatting options: Ctrl+1
There are many advantages, including that "regular math" will still work even if a shift starts in a different day than it ends.
If you must stick with only times, you can still calculate it correctly (up to a 23.9-hour shift) with an IF statement to add a day if the returned value is negative.
For example, if your existing formula works for same-day shift, and is:
=F50-D40
...then you could change it to:
=IF(F50-D40<0,F50+1-D40,F50-D40)

EDIT:
Looking at your question again, perhaps I misunderstood what you were trying to ndo. It's a little unclear, but you mention the fist and last times.
If you mean the "earliest and latest", you can get those using MIN and MAX. If the crossing-midnight is an issue here too, you'll need to see my first suggestion above, or else add a "helper column" to determine which times are before which.
Storing datetime is still best and this all would have been avoided.
try the below to get the difference in hours.
=(E50+F50)-(C40+D40)
