Compare Excel files
Comparing spreadsheets by eye is risky: an altered digit in the middle of a sheet is easily missed. Each sheet is flattened into rows of “cell → cell → cell” and then compared as text, so you immediately see which row has different values. It helps when checking estimates, price lists and exports from accounting systems, where a single price edit changes the total. Formulas are not evaluated: cell values are compared.
Supported: .conf, .css, .csv, .docx, .htm, .html, .ini, .js, .json, .log, .md, .pdf, .php, .py, .sh, .sql, .ts, .tsv, .txt, .xls, .xlsx, .xml, .yaml, .yml. Limit: 10000 lines for two documents. Nothing is stored — only a fingerprint of the pair stays on the server.

Questions and answers
Are formulas compared?
No, only the calculated cell values. Formulas are not taken into account.
Why is only part of the spreadsheet visible?
There is a limit: 5 sheets and 50,000 rows. The rest is truncated with an explicit notice.
Is CSV supported?
Yes, CSV is compared as plain text — it is a separate format.
Are differences in sheet names visible?
Yes, names are printed as separate heading lines, so a renamed sheet is visible immediately.
