CSV to JSON Converter

Turn spreadsheets and delimited exports into a clean JSON array of objects — quotes, commas and line breaks included.

About this tool

Tabular data lives in CSV; APIs want JSON. This converter parses your file with a full quoted-field implementation — fields that contain commas, escaped quotes ("") or line breaks are handled correctly — and produces a JSON array where the header row becomes the object keys.

How to use it

  1. Paste your CSV data (comma, semicolon, tab or pipe separated), or click Sample.
  2. Keep First row is a header checked if your file has column names; uncheck it to get an array of arrays instead.
  3. Click Convert to JSON and copy the result.

Good to know

  • Delimiter auto-detection picks the separator that appears most often in the first line.
  • Empty header cells get a generated name (column_1, column_2, …).
  • Everything is parsed in your browser — paste sensitive exports without worry.
