Frequently asked questions

Why look for an alternative to AllFileTools CSV Diff?

Most teams switching from AllFileTools CSV Diff cite one of: CSV only — no Excel or multi-format support; no key-column matching; no PDF export. 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 AllFileTools CSV Diff doesn't?

SheetCompare keeps your files on your machine — they're parsed in JavaScript inside your browser tab and never reach our servers. AllFileTools CSV Diff 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 AllFileTools CSV Diff actually the right tool?

Data analysts, QA testers, and accountants needing a fast free CSV diff with no friction. If your workflow centers on upload-based CSV comparison or added/removed/modified row detection, AllFileTools CSV Diff 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?
