SheetCompare
Browser-based spreadsheet diff that compares CSV, XLSX, XLS, and TSV files cell-by-cell without uploading them anywhere — files are parsed and diffed entirely in the browser.
Strengths
- client-side parsing — files never leave your browser
- cell-by-cell comparison with per-cell highlighting
- added, removed, and changed row detection
- header mismatch detection across files with different column orders
- junk-row detection for messy real-world exports
Limits
- no formula or VBA-level comparison — values only
- no desktop app
- free tier capped at 5,000 rows per file
Meld
Free, open-source visual diff and merge tool for developers on Linux/Mac, with Git/SVN integration — no spreadsheet-specific features.
Strengths
- 2- and 3-way file comparison
- directory comparison
- in-place file editing during diff
- version control system integration (Git, Mercurial, SVN, Bazaar)
- regex text filtering
Limits
- no Excel or CSV spreadsheet support
- no browser-based option
- primarily Linux/Mac — limited Windows experience
- developer-only audience
- no export to PDF or Excel
- no cross-format comparison

Frequently asked questions
What's the main difference between SheetCompare and Meld?▾
Browser-based spreadsheet diff that compares CSV, XLSX, XLS, and TSV files cell-by-cell without uploading them anywhere — files are parsed and diffed entirely in the browser. Free, open-source visual diff and merge tool for developers on Linux/Mac, with Git/SVN integration — no spreadsheet-specific features. The practical difference: SheetCompare keeps your data in the browser tab; Meld also runs locally but is built for linux and mac developers needing a free visual diff tool for code and version control workflows.
Is SheetCompare cheaper than Meld?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. Meld is free for the base tier. For most spreadsheet diff workflows the price gap isn't the deciding factor — the privacy model and the cross-format support usually are.
Can Meld compare CSV against XLSX?▾
Meld is primarily focused on 2- and 3-way file comparison, so cross-format diffs typically require converting one file first. SheetCompare handles cross-format natively — the parser layer normalizes both inputs before the diff runs.
When should I pick Meld over SheetCompare?▾
Meld is the right choice if your workflow needs: 2- and 3-way file comparison, directory comparison, in-place file editing during diff. Those are real strengths and we don't try to match all of them.
Where does SheetCompare run?▾
Entirely in your browser. JavaScript parses both files in-tab, the diff runs in-tab, and nothing is uploaded to a server. You can verify this in your browser's network tab while using the tool.
