Frequently asked questions
What's the main difference between SheetCompare and AllFileTools CSV Diff?▾
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 browser-based CSV comparison tool with row-level diff, summary counts, and delimiter customization — no signup required. The practical difference: SheetCompare keeps your data in the browser tab; AllFileTools CSV Diff also runs locally but is built for data analysts, qa testers, and accountants needing a fast free csv diff with no friction.
Is SheetCompare cheaper than AllFileTools CSV Diff?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. AllFileTools CSV Diff 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 AllFileTools CSV Diff compare CSV against XLSX?▾
AllFileTools CSV Diff is primarily focused on upload-based CSV 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 AllFileTools CSV Diff over SheetCompare?▾
AllFileTools CSV Diff is the right choice if your workflow needs: upload-based CSV comparison, added/removed/modified row detection, summary count reporting. 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.
