JSON API

/api/tools/json-to-csv-converter

POST JSON to this endpoint using the same field names as the form. Invalid input returns a structured 400 response.

curl -X POST https://tempkit.8u.ee/api/tools/json-to-csv-converter -H 'Content-Type: application/json' -d '{"input":"[{\"name\":\"Ada\",\"age\":36}]"}'

How it works

TempKit parses JSON with Jackson, flattens object fields, preserves column order, and prefixes formula-like values to reduce CSV injection risk.
