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.
