Page guide

Convert CSV to JSON.

⌑   Runs on your device

From rows to records

The first row supplies the field names. Every following row becomes one JSON object. Quoted separators, escaped quotes and multiline cells are supported.

Keep your data intact

Values remain strings, preserving leading zeros. Duplicate or blank headers and rows with inconsistent column counts produce an error. Choose the delimiter used by your file.

How to use CSV to JSON

  1. Enter csv in the input field.
  2. The result updates as you type. Adjust the available settings if needed.
  3. Review the result, then use Copy result or a download link when available.

What to expect

Convert CSV to JSON. Paste the source content and review the available settings. Inspect nested values, numbers, empty cells, and column names before reusing the result.
