How to use this converter

  1. Paste your CSV data into the input editor.
  2. Make sure the first row contains unique column headers.
  3. Click Convert to JSON to validate and transform the data.
  4. Copy the output or download it as a JSON file.

Values remain strings; the converter does not automatically change numbers, booleans, or empty fields into other JSON types. Your input is processed in your browser.
