⭐ JSON to CSV Converter - Explanation and Examples

The JSON to CSV Converter turns JSON objects and JSON arrays into a CSV file that you can open in spreadsheet software, import into a database, or use in another application. Everything is processed locally in your browser.

⭐ What Does This JSON to CSV Converter Do?

Paste JSON data or upload a .json file. The tool validates the JSON, creates columns from object properties, shows a limited preview for fast browsing, and lets you copy or download the full CSV output.

  • Converts a JSON object or an array of JSON objects into CSV records.
  • Uses all available object properties as CSV column headers.
  • Preserves missing values as empty CSV cells.
  • Escapes commas, quotes, and line breaks correctly.

⚙️ How to Convert JSON to CSV

  1. Paste JSON into the input field or select a JSON file.
  2. Choose a comma, semicolon, or tab delimiter.
  3. Choose whether to include headers and flatten nested objects.
  4. Select Convert JSON to CSV.
  5. Review the preview, then copy or download the CSV file.

🔎 Example: JSON Array to CSV

JSON input:

[
  {"name":"John","age":30,"active":true},
  {"name":"Jane","age":25,"active":false}
]

CSV output:

name,age,active
John,30,true
Jane,25,false

⚙️ Nested Objects and Arrays

When flattening is enabled, nested objects become dot-notated columns. For example, {"address":{"city":"Amsterdam"}} becomes an address.city column. Arrays remain JSON-encoded in one cell so no data is silently removed.

⚠️ JSON and CSV Formatting Tips

  • Use an object or an array of objects at the top level.
  • Use semicolons when your spreadsheet expects a European CSV delimiter.
  • Keep headers enabled when you need named columns in the exported file.
  • The preview is limited to the first 20 records, while the download includes all converted records.

⭐ Private Browser-Based Conversion

Your JSON file and generated CSV remain in your browser. The JSON to CSV Converter does not upload data to a server, requires no account, and is ready to use immediately.
