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
Beyond Compare
Long-established desktop file and folder sync/comparison tool used primarily by developers and IT for code, folder, and directory diffing.
Strengths
- file and folder comparison
- 3-way file merge
- syntax highlighting for code
- directory synchronization
- image comparison
Limits
- treats Excel files as generic binary/text — no spreadsheet intelligence
- no cross-format comparison
- poor handling of large spreadsheets
- complex interface for non-technical users
- no collaborative features
- Windows/Mac desktop only

Frequently asked questions
What's the main difference between SheetCompare and Beyond Compare?▾
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. Long-established desktop file and folder sync/comparison tool used primarily by developers and IT for code, folder, and directory diffing. The practical difference: SheetCompare keeps your data in the browser tab; Beyond Compare also runs locally but is built for software developers, system administrators, and it professionals needing file/folder synchronization and code diffing.
Is SheetCompare cheaper than Beyond Compare?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. Beyond Compare starts at $35/month. For most spreadsheet diff workflows the price gap isn't the deciding factor — the privacy model and the cross-format support usually are.
Can Beyond Compare compare CSV against XLSX?▾
Beyond Compare is primarily focused on file and folder 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 Beyond Compare over SheetCompare?▾
Beyond Compare is the right choice if your workflow needs: file and folder comparison, 3-way file merge, syntax highlighting for code. 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.
