CSV to JSON

Why Convert CSV to JSON?

CSV is the universal exchange format for spreadsheets, databases, and data pipelines. But web APIs, JavaScript applications, and NoSQL databases expect JSON. Our converter turns CSV rows into an array of JSON objects with automatic header detection, proper quoting, and custom delimiter support — entirely in your browser.

Features

  • Automatic header detection — the first row becomes object keys.
  • Custom delimiter — supports comma, semicolon, tab, pipe, or any single character.
  • Quoted field handling — correctly parses fields with embedded delimiters and escaped quotes.
  • Pretty-printed output — formatted JSON with 2-space indentation.
  • Copy to clipboard — grab the JSON with one click.

Common Use Cases

  • Importing spreadsheet exports into REST API requests or Postman collections.
  • Converting database dumps for use in MongoDB, Firebase, or DynamoDB.
  • Transforming CSV data feeds into JSON for front-end consumption.
  • Preparing test fixtures from CSV data files.
