How a comparison works

Three steps, with no uploads.

1Add the old and new filesCSV, TSV, XLSX, or XLS, up to 4 MB each. Choose a sheet when a workbook has more than one.
2Pick a shared keyUse an ID, email, SKU, or another column that identifies each row.
3Review every differenceAdded rows are green, removed rows are red, and changed cells are yellow.

Add both files to choose a matching column.

Safety note: cells beginning with =, +, @, or a nonnumeric minus are treated as text. Ordinary negative numbers stay numeric. Formulas are never executed.
