Use a formula like `=A2=B2` to check if two cells match
Use `=IF(A2=B2,”Match”,”No Match”)` to return a custom result
Use conditional formatting to highlight matching or different values
Use `=EXACT(A2,B2)` to compare values with case sensitivity
Use `=COUNTIF(B:B,A2)>0` to see if a value in one column exists in another
Use `=IF(ISERROR(MATCH(A2,B:B,0)),”No Match”,”Match”)` to compare against another column
Use `=A2<>B2` to test if two cells are different
Fill the formula down the column to compare all rows
Use `Filter` or `Sort` after adding a comparison helper column
Use `VLOOKUP` or `XLOOKUP` to compare values across columns and find missing items
