I have named the range C6:C13 'Date'. This is a dynamic range(the start date will vary) and in practice, it will be a very long column. E6 will be created from C6, so the cell E6 will be '=Date'. Rather than dragging this formula down a few thousand rows, I wish to be able to enter '=Date' in column E, and for it to fill as many rows as are filled in in Column C. The problem is that the amount of rows will vary, and if I just enter '=Date' in all of the rows down to 100k or whatever, of course '#VALUE!' will be entered in many rows below(I realise this is a non-issue in many cases but it's a big problem for me).
So is there a way to reference '=Date' in Column E, in only as many rows that are filled in column C?
=ifError(Date,"")
Should do what you want if I'm not mistaken

I have an Excel 2019 Workbook in which I have a sheet with a range of cells defined as a table. Table columns are A to H, where columns A and C contains formulas and the others have to be manually compiled with information by users. The sheet is protected, with the cells in columns without formulas unlocked, so that users cannot alter formulas, but they are allowed to add rows (in the middle of the table, not at its end) as this can be required.
The problem is that when adding rows, the formula auto-filled in column A for the row below the new one is incorrect.
Detailed explanation
Column A is used to assign an unique number to what si written in column B, so that if an element in column B is repeated, the corresponding number in column A is repeated as well
The first cell of the table in column A (A4) contains the value "1"
Cell A5 contains the formula "=IF(B5=B4;A4;A4+1)"
Cell A6 contains the formula "=IF(B6=B5;A5;A5+1)", and so on
If I add a row between 5 and 6, the formula in the new cell A6 is correct, but the formula in cell A7 becomes "=IF(B7=B5;A5;A5+1)", instead of the correct "=IF(B7=B6;A6;A6+1)"
Formulas in all the cells below A7 are correct
If I manually fill the formula in A7 form another cell by using the fill handle, the formula corrects itself
I know there is a similar thread MS Excel Auto-Fills Incorrect Formula When Adding Rows and I already tried some workarounds described there such as clear the column and then add the formula back again, but without results.
My situation seems to be different because the formula is not present in the entire column because of the "1" in A4.
Even though the problem can be manually addressed with little effort via the fill handle, this is not a suitable solution since users may not correct the formula, which is needed for some other calculations in another sheet of the Workbook.
The behaviour you describe is normal and nothing to do with tables. If you insert a row in between a cell and another cell it references directly in a formula, that formula will not adjust to refer to the new cell. In other words if A6 contains =A5 and you insert a row between rows 5 and 6, that =A5 will not suddenly alter to be =A6.
If you need that behaviour, you would need to use something like INDEX or INDIRECT - for example:
=INDEX(A:A,ROW()-1)
will always refer to the cell in the row above the formula cell.
In my worksheet in column F I have a list of names, that may appear or disappear according to other inputs in the spreadsheet. I want the cells in the columns G:AZ to remain blank if the corresponding cell (i.e. same row) in column F is also blank. Because I have thousands of cells to which I need to apply this, I'm using Pullover's Macro Creator to add this small change to all the formulas inside the cells really quickly, so I can do entire columns in seconds. In column J, for example, I've been applying this formula:
=IF(COUNTBLANK(INDIRECT("RC[-4]",0))=1,"",[this part changes and doesn't matter])
You can see that I need to change that "-4" to different numbers according to the column I'm working on. But I have so many columns that it's still going to be a pain to change that hundreds of times.
My question: Is there a formula I can use in the COUNTBLANK function that can reference the corresponding cell in column F without needing any changes in different columns and different rows? And since the INDIRECT formula is so volatile (I still don't know what that means, but I guess it's bad), is there a solution that doesn't use this formula?
I have a worksheet with two columns of data. Column A contains thousands of records, and Column B contains only a few records. I wish to identify which values in Column B do not exist in Column A, and display these in Column D. What is the quickest way to achieve this? Happy to use formulas, or otherwise.
I would use conditional formatting and filters:
Formula being:
=ISERROR(MATCH(A1,B:B,0))
I'd then filter on highlighted cells, select the cells in column A and use Alt+; to select only the visible cells, then paste in D.
Last, I'd clear all the conditional formatting and clean up anything left.
Using formulae would be a little more complex; usually the most of the time would be spent designing it, and it's an array formula (invoked correctly only with Ctrl+Shift+Enter):
=IFERROR(INDEX($A$1:$A$27,SMALL(IF(COUNTIF($B$2:$B$6,$A$2:$A$27)=0,ROW($A$2:$A$27),9^99),ROW(D1))),"")
The formula can also take some time to calculate for larger datasets.
Not really an Excel user, but what seemed simple has turned out to be very difficult for me. I am in trouble as I can't come up with a nice and clean (or any) way to get it working.
What I have here:
I need to create a new columnn that would tell the amount of employees in each occupation while ignoring the duplicates (highlighted).
The amount of names formula is working, so maybe this can be used ? Or maybe it's just in the way and should be cleared.
It's just:
=COUNTIFS(A:A;A2)
Tried searching for quite a while did not find anything suitable. Any help or advice would be much appreciated. I hope I explained it in clear manner.
Thank you
Without helper columns:
Two options, D2:
{=SUM(--(FREQUENCY(IF($B$2:$B$9=C2,MATCH($A$2:$A$9,$A$2:$A$9,0)),ROW($A$2:$A$9)-ROW($D$1)+1)>0))}
Or put in E2:
{=SUMPRODUCT((($B$2:$B$9=C2))/COUNTIFS($B$2:$B$9,$B$2:$B$9&"",$A$2:$A$9,$A$2:$A$9&""))}
Notice both are array formulas and should be entered through CtrlShiftEnter
SUMPRODUCT 'Deals' in Arrays 3
You might have employees with the same name (David, Michael) in different occupations (Tech & Worker, Tech & Economy). To distinguish those from each other, in B2 you can use:
=SUMPRODUCT((A$2:A$21=A2)*(C$2:C$21=C2))
In D2 you can use:
=SUMPRODUCT((1/B$2:B$21)*(C$2:C$21=C2))
Distinct Employees Occupation Count
with a helper column
Unique and Distinct values are tricky. Using a helper column is beneficial for identifying either one of these when coupled with an expanding range:
=SUMPRODUCT((A2=$A$1:$A1)*(C2=$C$1:$C1))
Relative Rows: ^ ^
Paste to cell E2.
Copy Drag the formula down from the where pasted.
The relative row numbers identified above well increase as the formula is copy dragged down. This creates a larger and larger range for comparison. An expanding range.
In this case the range that is expanding is the range of already checked values. Many times the result range is expanded and tested against to eliminate posting duplicates of already posted results in subsequent rows of the results list.
The helper column's value is how many times the name and occupation pair has previously appeared. Zero previous appearances tells us this is the first occurance. We will only count the zeros (first occurance) in the main formula.
The main formula for counting distinct employees in each occupation:
=COUNTIFS( $C$2:$C$9, C2, $E$2:$E$9, 0)
Paste to cell D2.
Copy Drag the formula down from the where pasted.
Here we count all the rows for this row's occupation where the occupation matches the range of listed occupations and for that particular row in the list of occupations, the helper column row value is zero.
Add a final column which is the concatenation of the prior 3 columns then use
=SUMPRODUCT(1/COUNTIF(D2:D9,D2:D9))
There is a good explanation of this formula here. Basically, values that appear once will count as 1. Values that appear more than once will appear as fractions of their total occurrence count and be summed to 1.
If you convert your data to an Excel table by selecting a populated cell in the range and pressing Ctrl+T, then formulas will auto-populate down last column. You can then reference the table columns in the formula and you won't need to amend the formula as you add rows.
I have a column with dates called "dates". This column contain dates from 01.01.2010 to 31.12.2010. it should have about 365 rows, but it actually has only 231 rows, because the data was not collected regularly. The others are missing, and I'd like to fill the gaps in time.
How can I fill the array of this column with the missing dates? I want to add 134 rows in the place of the missing ones, filling in the missing dates.
Create another sheet and put all the dates in column A in your new sheet.
Make sure your sheet with the data in it has the data column all the way on the left (important for how Vlookup works)
In your new sheet, starting in Cell B2 put numbers 1 through however many columns you have in your data sheet along that top row.
In your new sheet use Vlookup to find all the rows where there are data
=VLOOKUP($A2,DataSheet!$A$1:$C$20,B1,FALSE)
Note that the lookup column ($A1) is locked in to the column but not the row and that the range you are looking up is locked in in all directions. This will allow you to drag to the right/down and fill everything in.
Drag to the right then drag all the way down.
there will be #N/As where you cannot find a match which you can suppress with either an IF statement of conditional formatting. But now you have a row for every day with blanks when there is not data!
I found a solution with a similar formula, but the result was the same.
First, I got the two columns of data—"date" and "values" in the columns A and B of the worksheet. Each consisted of 231 rows. Then, I spread a full array of dates—365 in a new column D. Finally, I used this formula:
=VLOOKUP(D2;$A$2:$B$1056;2;FALSE)
in C2 and obtained the only the values from column "values" corresponded to the new dates of column D.
Thanks for Brad's answer for directing me to the VLOOKUP function.
