PayloadForge, the Spreadsheet-to-API Workbench

Field notes

PayloadForge accepts an existing cURL request, an example JSON payload, or a manually defined target, then turns imported CSV rows into mapped request data. Its visible builder includes header controls, schema detection, field typing, transformations, and JSON/cURL output. The example deliberately exposes a validation failure: a revenue field containing “₹3,83,000” is rejected where a numeric value is required. The page says the core workflow runs in a browser without signup.
