I have a large spreadsheet with I think 1000 formulas and I want to move them to an older version of the Google Sheet, because of the enhanced protection options I have there. (Basically I need to keep some sheets only for some people, while the rest to all with the link).
The tabels are not mine, so I don't know the logic of them - I just need to port them to the older version. Example of a formula is:
=SUMIFS('FC Eingabe'!$K$2:$K$142,'FC Eingabe'!$R$2:$R$142,"August",'FC Eingabe'!$S$2:$S$142,"100% | Auftrag erteilt")
Changing the SUMIFS to a solution from SUMIFS function in Google Spreadsheet is too time consuming to be worth it.
Is there any way I could add something like a custom function SUMIFS to that old Google Sheet? - something like a VBA piece of code, maybe. Or an add-on.
Please help!
