CSV to JSON Converter

Convert between CSV and JSON in either direction, right in your browser.

What is the CSV to JSON Converter?

This tool converts tabular CSV data into a JSON array of objects (using the first row as field names), or the reverse — a JSON array of objects back into a CSV table. Both directions handle quoted fields correctly, including commas or quotation marks embedded inside a quoted CSV value.

How to use it

  1. Pick a direction: CSV to JSON, or JSON to CSV.
  2. Paste your data into the input box.
  3. Click Convert and copy the result.

CSV is the common export/import format for spreadsheets and databases, while JSON is what most web APIs and JavaScript code expect — this conversion comes up constantly when feeding spreadsheet data into a script, or exporting API results into a format non-technical teammates can open in a spreadsheet program. Everything happens locally in your browser.
