JSON to CSV Converter
Convert JSON arrays to CSV format. Download the result as a .csv file.
What is JSON to CSV Conversion?
The JSON to CSV converter turns an array of JSON objects into a clean comma-separated table — each object becomes a row and each key becomes a column — ready for Excel, Google Sheets, or any data tool. Paste your array, click convert, then download the .csv or copy it to the clipboard in one click. Conversion runs entirely in your browser: your data is never uploaded, so sensitive records stay private from paste to download.
Why use this converter?
The converter collects the union of keys across all objects, so rows with missing fields still align to the right columns — no manual cleanup. Nested objects and arrays are serialized as compact JSON strings in their cells, preserving the data instead of dropping it. Because everything is client-side, there is no server queue and no row limit imposed by an upload; a thousand-row export takes milliseconds.
How to use the converter.
- Paste a JSON array — each object in the array becomes a row
- Click "Convert to CSV" to generate the table
- Download as .csv or copy to clipboard
Example input: [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]

FAQ.
What JSON structure does it expect?
An array of objects. Each object becomes a row, and all unique keys across objects become column headers.
How are nested objects handled?
Nested objects and arrays are written as compact JSON strings inside their CSV cells, so no data is lost. For flat analysis, flatten the JSON first.
Will the CSV open in Excel?
Yes. The output uses standard comma separation and quoting and opens directly in Excel, Google Sheets, Numbers, and similar spreadsheet apps.
Is my data uploaded to convert it?
No conversion happens on a server. The CSV is generated locally in your browser and downloaded straight from your device — your data never leaves it.
Can I convert CSV back to JSON?
Not in this tool — start from the JSON Formatter to reshape your data, or use the JSON to YAML / TypeScript converters for other formats.
