Free Excel Compare Tool
Compare Excel, ODS, and CSV files by row order or key column, then inspect added rows, removed rows, changed sheets, and cell-level differences.
Browser-side Excel comparison
Choose local spreadsheet files. Parsing and comparison run inside this browser session.
Upload the original spreadsheet
Supports XLSX, XLS, XLSM, XLSB, ODS, FODS, and CSV.
Upload the modified spreadsheet
Compare the same sheet name, or choose different sheets manually.
Use row order for quick checks. Use a key column when rows may be sorted differently.
Compare business exports
Use spreadsheet comparison for price lists, inventory exports, customer records, finance reports, and operational sheets where row identity matters.
Match by key column
When rows are sorted differently, select a shared key column such as SKU, ID, email, invoice number, or account code before reviewing cell changes.
Review sheet changes
The tool highlights added and removed sheets before showing row-level and cell-level changes inside the selected sheets.
