About this tool

Pure browser-side CSV to JSON converter. Detects delimiter, handles quoted fields, and outputs an array of objects keyed by your header row. Useful for prepping fixture data, API payloads, and quick analysis in tools that don't take CSV.

Common uses

  • • Convert a spreadsheet export to a JSON payload for a REST API
  • • Build fixture data for tests from a CSV of sample records
  • • Feed CSV data into tools that only accept JSON (some BI dashboards)
  • • Generate an array of objects you can pipe into a JS console for ad-hoc analysis

Type coercion: with coercion on, "123" becomes a number, "true"/"false" become booleans, and empty fields become empty strings. Turn it off if you want every value as a string for downstream type strictness.
