    Post Adjust formula to allow for changing sheet reference.

    I was using the formula below which was working fine for copying across 20 columns and down however many rows, but now the requirements have changed to 90 columns. I have tested this out with the 90 columns but the Indirect function is bogging down the spreadsheet with the constant recalculating.

    =IFERROR(INDIRECT("'"&COLUMNS($A$1:A$1)&"'!P"&ROWS($A$1:$A8)),"")

    I rearranged the formula to the one below, but how can I have the reference to the sheet name changed as in the formula above without using the Indirect?

    =IFERROR(INDEX('1'!$A$8:$AT$115,MATCH($A3,'1'!$A$8:$A$115,0),MATCH("PAT",'1'!$A$7:$AT$7,0)),"")

    The sheet reference will change from '1' through '90'.

    Re: Adjust formula to allow for changing sheet reference.

    One way would be to add a macro that can insert formulas into each row based on the the correct sheet name reference, however you want the macro to determine that. The main goal is to have normal direct formulas in the cells.

    Hi JB,

    Yes I was thinking about a macro, but would some type of loop work replacing each sheet reference with the next variable starting from 1?

    Hi again JB,

    So far I have come up with this, but it change the '1' to '2' throughout the range B1:H1. What am I missing to make it loop through all the numbers up to 7. I am just testing a small scale right now so therefore up to only 7.

    If we're going to go the macro route, there's no reason not to let the macro simply collate your report for you with no formulas. You simply want the data from row1 on every sheet collated into a report on sheet1? That's probably easiest of all.

    Just delete the macro you were using. Then open the SHEET MODULE for this sheet and insert the macro above into the sheet module. This will cause the macro to run itself every time you bring the sheet up onscreen...which makes it as effective as =A1 formulas.

    In case you don't know...the sheet module is listed above the regular modules, open the actual module with the sheetname that is your 'report'. Another way to open it is to right-click on the sheet tab and select VIEW CODE.

    Hi JB,

    That doesn't seem to be what I am looking for. I attached a small sample wb so you can see what I am trying to accompllish.

    On the PAT sheet starting in cell A2 I need to copy the formula to the right over 90 columns but with every cell stating in B2 the formula needs to reference sheet '2' and so on until '90'.

    Again, I was using the Indirect formula which worked fine, but now with the spreadsheet getting bigger and the volatile nature of the Indirect I needed to change to another formula so I went with the Index/Match.

    Index/Match works fine, but without manually changing all of the sheet references how can I automate the process.

    If this is possible then I can even do away with the Index/Match and just simple go with '1'!A1,'2'!A1,'3'!A1,'4'!A1,'5'!A1,'6'!A1,'7'!A1 and so on util '90'.

    So row 2 is all you need? There's no row 3 formulas, and row 4?

    This standalone macro goes in a standard module. Run it and will create formulas in row2 based on the sheet names found in row1. They don't have to be 1,2,3...etc. They can be anything. You'll get a normal REF# error if the value in row1 doesn't match an existing sheet.

    You can duplicate the syntax in the red line of code to add more formulas to get data from other cells on each sheet.
