Description
JSON Support is a free, no-signup tool that converts JSON and CSV data into formatted Excel spreadsheets instantly — paste or upload, and download a clean .xlsx file with no account required and nothing stored. For teams building it into their own product, JSON Support also offers a rate-limited developer API (free tier to start, paid tiers for production use), including reverse conversion (Excel/CSV back to JSON), a standalone JSON formatter/validator, and no-code inbound webhooks for automation tools like Zapier.Have a startup you want to promote?
