Terms of service
Effective 2026-10-02. By using Diffwise Spreadsheet Compare you agree to these terms.
The service
Diffwise Spreadsheet Compare is a tool provided by Zovo for use inside ChatGPT, Claude, and other MCP clients. Diffwise Spreadsheet Compare compares two versions of a spreadsheet (CSV or Excel) and lists the differences: rows added, rows removed, and rows changed cell by cell with old and new values, the numeric change and the percent change. It finds the key column automatically (and says why), handles reordered rows, renamed and moved columns, total rows, number formats such as 1,200.00 vs 1200, and dates stored as text or as Excel serials. The full change set downloads as an Excel workbook and a CSV.
