- 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
DiffEngineX
Windows desktop Excel comparison tool with character-level cell diffing and VBA macro comparison — one of few tools with sub-cell granularity.
Strengths
- character-level cell comparison
- VBA code comparison
- formula and value comparison
- row/column alignment with primary key
- output diff report into new workbook
Limits
- Windows-only, requires Excel installation

Frequently asked questions
What's the main difference between SheetCompare and DiffEngineX?▾
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. Windows desktop Excel comparison tool with character-level cell diffing and VBA macro comparison — one of few tools with sub-cell granularity. The practical difference: SheetCompare keeps your data in the browser tab; DiffEngineX also runs locally but is built for power excel users and developers on windows needing granular cell-level and vba comparison with automation via command line.
Is SheetCompare cheaper than DiffEngineX?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. DiffEngineX 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 DiffEngineX compare CSV against XLSX?▾
DiffEngineX is primarily focused on character-level cell 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 DiffEngineX over SheetCompare?▾
DiffEngineX is the right choice if your workflow needs: character-level cell comparison, VBA code comparison, formula and value comparison. 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.
