Frequently Asked Questions

How does the comparison work?

Select a key column (like ID or email) to match rows between sheets. The tool then compares each cell to find differences, additions, and deletions.

What if sheets have different columns?

The tool will compare only common columns and report which columns are unique to each sheet.

Can I compare sheets from different files?

Yes! Upload your Excel file and select any two sheets to compare, whether from the same workbook or loaded separately.

Purpose-built for accountants and auditors who need a defensible record of exactly what changed between two versions of a workbook.
