Frequently asked questions
What's the main difference between SheetCompare and ToDiagram 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. Modern browser-based CSV/JSON/YAML/XML diff tool with visual diagram output — focused on data pipeline and QA validation use cases. The practical difference: SheetCompare keeps your data in the browser tab; ToDiagram CSV Diff processes files server-side, which is a hard blocker for sensitive data.
Is SheetCompare cheaper than ToDiagram CSV Diff?▾
SheetCompare starts free (5,000 rows per file, no signup). Pro is $12/month. ToDiagram 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 ToDiagram CSV Diff compare CSV against XLSX?▾
ToDiagram CSV Diff is primarily focused on CSV, JSON, YAML, XML comparison in one tool, 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 ToDiagram CSV Diff over SheetCompare?▾
ToDiagram CSV Diff is the right choice if your workflow needs: CSV, JSON, YAML, XML comparison in one tool, header and field-level change detection, schema change detection (renamed columns). 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.
