Excel Compare Online
Upload two XLSX, XLS, or CSV files, read every worksheet in workbook order, and highlight changes in the extracted values.
Compare workspace
Choose two spreadsheets up to 8 MB each. The files stay in this browser workspace while their worksheet values are extracted for comparison.
Why use Excel compare
Use it for exported reports, price lists, inventories, and other spreadsheets where value changes matter.
XLSX, XLS, and CSV input
Compare two files of the same or different supported spreadsheet formats.
Every worksheet in order
Worksheet names and extracted values are serialized in workbook order before the character diff runs.
Clear result limits
Review value changes without treating formatting, formulas, cell addresses, or moved rows as spreadsheet-aware changes.
