Frequently asked questions
Why look for an alternative to Copyleaks Text Compare?▾
Most teams switching from Copyleaks Text Compare cite one of: not a spreadsheet comparison tool; no Excel or CSV support; comparison feature is secondary to plagiarism detection. 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 Copyleaks Text Compare doesn't?▾
SheetCompare keeps your files on your machine — they're parsed in JavaScript inside your browser tab and never reach our servers. Copyleaks Text Compare requires uploading files to its servers, which matters when you're diffing payroll, financial, or PII data that can't legally be shipped to a third-party SaaS.
When is Copyleaks Text Compare actually the right tool?▾
Writers, academics, and legal professionals checking for text similarities — not a data comparison audience. If your workflow centers on text comparison with difference highlighting or PDF and document comparison, Copyleaks Text 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.
