Compare two Excel files and see every supported change
About WorkbookDiff
Compare two XLSX workbook versions directly in your browser. WorkbookDiff separates value changes from formula-expression changes, detects added or removed sheets, visibility changes, hidden rows and columns, and used-range updates, then exports a searchable CSV difference report. No signup is required, files stay in browser memory, and the product clearly lists unsupported formats and workbook features.
