Use `=A1=B1` to check if two cells match
Use `=IF(A1=B1,”Match”,”No Match”)` to return a custom result
Use Conditional Formatting to highlight matching or different values
Use `=EXACT(A1,B1)` to compare text with case sensitivity
Use `=COUNTIF($B:$B,A1)>0` to see if a value in one column exists in the other
Use `=IF(ISERROR(MATCH(A1,$B:$B,0)),”No Match”,”Match”)` to compare against another column
Use `=A1<>B1` to check if two cells are different
Copy formulas down the column to compare all rows
Use filters to show only matching or non-matching results
Use `=IF(AND(A1<>“”,B1<>“”),IF(A1=B1,”Match”,”No Match”),””)` to ignore blank cells
