Compare Two Excel Spreadsheets Online
Upload two versions of a spreadsheet and Maplesheet highlights every difference between them — changed cell values, modified formulas, formatting and style changes, and rows or columns that were added or removed. The comparison runs entirely in your browser, so your files never leave your computer.
It works with .xlsx, .xls, and .csv files. Use it to review edits before sharing a report, reconcile two data exports, or see exactly what a colleague changed in a shared workbook.

How it works
- Upload your first (original) Excel file on the left.
- Upload the second (updated) file on the right.
- Maplesheet aligns the sheets and highlights every changed cell, formula, and style.
- Added and deleted rows and columns are flagged so nothing slips through.
- Scroll through the merged diff view to review each difference in context.
