Frequently asked questions
What's the main difference between SheetCompare and Synkronizer?▾
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-specific comparison and merge add-in with 19+ years in market, focused on database consolidation and multi-worksheet workbook comparison. The practical difference: SheetCompare keeps your data in the browser tab; Synkronizer also runs locally but is built for excel power users and data managers who need to consolidate and compare large multi-sheet workbooks inside excel.
Is SheetCompare cheaper than Synkronizer?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. Synkronizer 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 Synkronizer compare CSV against XLSX?▾
Synkronizer is primarily focused on Excel add-in (runs inside Excel), 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 Synkronizer over SheetCompare?▾
Synkronizer is the right choice if your workflow needs: Excel add-in (runs inside Excel), multi-worksheet comparison, row/column insertion 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.
