CSV and JSON comparison by key, running locally in your browser or Node.js.
Changes
- Exact decimal tolerance, including adjacent large CSV integers.
- Parsing and comparison in a cancellable worker.
- Refreshed dependencies and 42 automated tests.
Downloads
- CLI ZIP: Node.js 22.13+, no npm install. Includes the decimal module and examples.
- Web ZIP: built static app with relative asset paths. Extract and serve over HTTP; file:// is unsupported.
- SHA256SUMS.txt: checksums for both archives.
Both ZIPs were extracted and checked. The CLI sample and large-integer regression pass; the extracted web app correctly compares reordered rows and Chinese text. Third-party licenses are included.
Linux/Windows tests on Node.js 22/24, web build and release packaging checks passed in CI.
No XLSX, fuzzy matching, file merging or offline page refresh. See the README for input limits.
