JSON to CSV Converter enables you to convert JSON arrays of objects into CSV format with precise control over delimiters and header inclusion. Utilizing the PapaParse library, it generates RFC 4180 compliant CSV files while flattening nested objects for accurate data representation. Since all processing happens client-side in the browser, your JSON data remains private with zero uploads. For additional JSON manipulation, consider using related tools like Json Formatter for readable JSON output or Csv To Json for reverse conversion.

How to Use JSON to CSV Converter

  1. Paste or upload your JSON array of objects into the input field. Each object should represent a CSV row.
  2. Choose your preferred delimiter: comma, semicolon, or tab to match your target CSV format.
  3. Toggle the option to include or exclude the header row based on your import requirements.
  4. Click the convert button to generate the CSV output instantly in your browser.
  5. Download the resulting file or copy the CSV text for use in spreadsheets or data pipelines.

How It Works

This tool uses the PapaParse library, a well-established JavaScript CSV parser and generator. It accepts a JSON array of objects where each object maps keys to values. The converter flattens nested objects by concatenating nested keys with dots, ensuring complex JSON structures become valid CSV rows. The CSV output adheres to RFC 4180 standards, including proper escaping of commas, quotes, and line breaks. You can configure delimiters, allowing compatibility with different regional CSV formats (e.g., semicolon for European locales). Because all processing occurs client-side, no data is transmitted to servers, ensuring full privacy.

Example

Input JSON:

[
  { "name": "Alice", "age": 30, "location": { "city": "New York", "state": "NY" } },
  { "name": "Bob", "age": 25, "location": { "city": "Los Angeles", "state": "CA" } }
]

Output CSV (comma delimiter, with header):

name,age,location.city,location.state
Alice,30,New York,NY
Bob,25,Los Angeles,CA
