About Compare Excel

Compare Excel files when a price list, budget or class roster comes back edited and you need to know exactly what moved. Upload the original and the changed version, and we return the changed workbook with every altered cell filled yellow and a comment showing what it used to say. New rows are green. Two versions of a Word document can be checked with Compare Word, which highlights every edit.

A Summary sheet at the front lists each change with its sheet, row, column, old value and new value, so you can review them one by one or filter them. Sheets are matched by name, and cells are compared by position. If someone inserted a row near the top, every row below it will show as changed, so line both files up the same way first when you can.

FAQ

Compare Excel: questions and answers

How does Compare Excel match the two files?
Sheets are paired by name, or by position if the names differ, and cells are compared at the same row and column. Displayed values are compared, so 5 and 5.0 count as the same.
Why does every row after a certain point show as changed?
A row was probably inserted or deleted in one version, which shifts everything below it. The comparison goes by position, so add or remove that row in one file, or sort both the same way, then compare again.
Can I compare Excel files with CSV exports?
Yes. You can mix XLSX, XLS, CSV and ODS, for example to check last month's workbook against a CSV export from your system. The result is always an XLSX. If the export has stray spaces or numbers stored as text, tidy it first with Excel & CSV Cleaner.
Is it free to compare two Excel files?
A comparison of two files is one task. Visitors get 2 tasks and free accounts 2 a day, with files up to 50 MB, while VIP has no daily limit and a 1 GB file size.
Who can see my spreadsheets?
No one. The files travel over HTTPS, are compared in an isolated process and are deleted after one hour. We don't look at data or use it for AI training.
