This is current formula
=IF(Sheet1!A1="?","Check",IF(Sheet2!A2="?","Check",""))
(nested IF formula)
This is what formula should do: If any A1 cell from Sheet1 to Sheet100 has ? written in cell, than write in cell in which is this code word Check.
Question
How to write fast this formula without having to type all 100 IF formulas? And if so, any tip to write them faster?
Best would be if we can skip VBA since I can't use it on android Excel version.
Thanx
