Compare two Excel files
See which rows were added, which were removed, and which cells changed between two versions.
How it works
Your file is opened in an isolated sandbox with no internet access, processed, and the sandbox is destroyed. Nothing is stored, and no account is needed.
It uses the same reader as the full product, which is built for the spreadsheets people actually have: headers that are not on row 1, merged cells, totals rows pasted at the bottom, dates in two formats, and numbers stored as text. Everything it changes is listed back to you.
Common questions
How does it match rows between the two files?
It looks for a column whose value is unique on every row in both files — an invoice number, an order ID, an SKU — and matches on it. If there is none, it compares whole rows instead and tells you so.
What if the columns are in a different order?
Columns are matched by name, not position. Columns that exist in only one file are listed separately.
What does the result contain?
A workbook with the rows only in the first file, the rows only in the second, and — when rows can be matched — one line per changed cell showing the old and new value.
Does 500 vs 500.00 count as a change?
No. Numbers are compared as numbers and text is compared without surrounding spaces, so formatting differences are not reported as changes.
