Frequently asked questions
Why look for an alternative to TestMu AI CSV Compare?▾
Most teams switching from TestMu AI CSV Compare cite one of: CSV only — no Excel support; no key-column intelligent matching; comparison is one feature of a broader QA testing platform. SheetCompare is purpose-built for spreadsheet diffs, runs entirely in the browser, and doesn't lock core features behind a desktop install.
What does SheetCompare do that TestMu AI CSV Compare doesn't?▾
SheetCompare keeps your files on your machine — they're parsed in JavaScript inside your browser tab and never reach our servers. TestMu AI CSV Compare is also client-side, but matters when you're diffing payroll, financial, or PII data that can't legally be shipped to a third-party SaaS.
When is TestMu AI CSV Compare actually the right tool?▾
QA engineers, developers, and data testers validating CSV data exports and test data sets. If your workflow centers on upload-based CSV comparison or row/column/cell-level difference detection, TestMu AI CSV Compare may still be the best fit.
Is SheetCompare free?▾
Yes — comparing files up to 5,000 rows is free with no signup. Pro is $12/month for files up to 100,000 rows, unlimited saved diffs, and API access. Team is $39/month with shared workspace and SSO.
Can I compare CSV against XLSX directly?▾
Yes. Cross-format comparison is built in — drop a CSV on one side and an XLSX on the other and SheetCompare normalizes them after parsing.
