Frequently asked questions
Why look for an alternative to Microsoft Spreadsheet Compare?▾
Most teams switching from Microsoft Spreadsheet Compare cite one of: requires Microsoft 365 Enterprise or Office Professional Plus — not available on standard/personal plans; both files must be open in Excel before comparing; Windows-only. 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 Microsoft Spreadsheet Compare doesn't?▾
SheetCompare keeps your files on your machine — they're parsed in JavaScript inside your browser tab and never reach our servers. Microsoft Spreadsheet 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 Microsoft Spreadsheet Compare actually the right tool?▾
Enterprise Excel users on Microsoft 365 Apps for Enterprise who need a built-in comparison tool without installing third-party software. If your workflow centers on cell-by-cell Excel workbook comparison or color-coded diff by content type (values, formulas, formats, named ranges), Microsoft Spreadsheet 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.
