Excel if match formula: check if two or more cells are equal

This Excel tutorial demonstrates various methods for comparing cell values, returning logical results, custom text, or data from other cells. We'll explore solutions beyond the simple A1=B1 comparison, addressing scenarios where this basic approach falls short.

Comparing Two Cells:

Several variations of the IF function exist for comparing two cells:

• Return TRUE/FALSE: The simplest method is =A2=B2, returning TRUE for identical cells and FALSE otherwise. This is case-insensitive.

• Return Custom Values: Use =IF(A2=B2, "yes", "no") to return "yes" for matches and "no" otherwise. You can adapt this to return any desired values or even a blank cell ("").

• Return Value from Another Cell: To copy a value from a third cell upon a match, use =IF(A2=B2, C2, ""). This copies the content of C2 if A2 and B2 are identical.

• Case-Sensitive Comparison: For case-sensitive matching, employ the EXACT function: =IF(EXACT(A2, B2), "Yes", "No").

Comparing Multiple Cells:

Several approaches exist for comparing multiple cells:

• AND Function: The AND function checks if multiple conditions are true. =AND(A2=B2, A2=C2) returns TRUE only if all cells are equal. For custom results, nest it within an IF statement.

• COUNTIF Function: =COUNTIF(A2:C2, A2)=COLUMNS(A2:C2) counts occurrences of a cell's value within a range. If the count equals the number of cells in the range, all cells are identical. Again, nesting within IF provides custom outputs.

• Case-Sensitive Multiple Cell Comparison: Combine EXACT and AND for case-sensitive multiple cell comparisons: =AND(EXACT(A2:C2, A2)). Remember to use Ctrl Shift Enter in older Excel versions.

Checking if a Cell Matches Any Cell in a Range:

• OR Function: Use OR(A2=B2:D2) (array formula in older Excel versions) to check if A2 matches any cell in B2:D2.
• COUNTIF Function: =COUNTIF(B2:D2, A2)>0 provides a more concise alternative. Both can be nested within IF for custom results.

Comparing Two Ranges:

To compare two ranges cell-by-cell, use =AND(B3:F6=B11:F14). This returns TRUE only if all corresponding cells match. An IF statement allows for custom output.

This comprehensive guide offers various Excel formulas for cell comparison, catering to diverse needs and scenarios. Remember to adjust formulas to your specific cell references and desired outcomes. A practice workbook is available for hands-on learning.
