I came up with below vlookup formula and apply it on column C of sheet 2 but it gives error Invalid Cell Reference Error
=VLOOKUP(Sheet1!A:A,A:A,Sheet1!B:B,FALSE)
In the column c of Sheet2 use this vlookup formula.For example in Sheet2, cell c2 if you paste this formula. =VLOOKUP(A2,Sheet1!A:B,2,FALSE)
The formula will look for the value in cell A2 of Sheet2 in Column A of sheet1 and return the corresponding value in columnB(exact match)of Sheet1 to Cell c2 in sheet2.
Hope this helps!
