Frequently asked questions
What's the main difference between SheetCompare and Ablebits Compare Sheets?▾
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. Excel add-in bundled in the Ultimate Suite — a 70+ tool power pack for Excel users, with Compare Sheets as one feature among many. The practical difference: SheetCompare keeps your data in the browser tab; Ablebits Compare Sheets also runs locally but is built for excel power users who want a full productivity suite — comparison is a secondary use case, not the primary purchase driver.
Is SheetCompare cheaper than Ablebits Compare Sheets?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. Ablebits Compare Sheets starts at $49/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 Ablebits Compare Sheets compare CSV against XLSX?▾
Ablebits Compare Sheets is primarily focused on compare sheets by key columns or no-key mode, 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 Ablebits Compare Sheets over SheetCompare?▾
Ablebits Compare Sheets is the right choice if your workflow needs: compare sheets by key columns or no-key mode, color-coded difference highlighting, duplicate and unique row detection. 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.
