About the CSV to JSON
CSV is everywhere, but APIs and JavaScript code want JSON. This converter parses CSV correctly, including quoted fields that contain commas, quotes or line breaks, and maps each row to an object using the first row as keys.
The conversion is fully local, so you can transform exports containing sensitive data without uploading anything. The result is indented JSON ready to drop into code, a request body or a test fixture.
