I need to lookup cell values on multiple sheets (tabs in current sheet) and generate a simple report on a sheet/tab named "REPORT" of the current Google Sheet.
Sheetname1 Lookup column A for X, provide corresponding value in column B on those rows
Sheetname(N) Lookup column A for X, provide corresponding value in column B on those rows
Simple enough, I know, but I am a novice at Google Sheets functions, and it would take me days to figure it out from other sample formulas...
=vlookup(X, Sheetname1!A:B, 2, false)
does what you want, except it's not clear why you say "rows" in plural (and "value" in singular). Can you clarify whether multiple rows of those sheets might be matching X, and if so, what do you want to happen in that case?
