How to use the jSON to CSV

Paste a JSON array of objects, like [{"name":"Alex","age":30}], into the input box.
Click 'Convert to CSV'.
Review the CSV output, using the same column headers as your JSON keys.
Copy the result or download it as a .csv file.

Example

Converting [{"name":"Alex","age":30},{"name":"Sam","age":25}] produces a CSV with header row name,age followed by one row per object.

Why convert JSON to CSV?

APIs and export tools often return JSON, but spreadsheets and many data-import tools expect CSV. This tool bridges the gap without needing a script or command-line tool.

Handles inconsistent keys sensibly

Column headers are taken from the union of keys across all objects in the array, so even slightly inconsistent JSON objects convert into a sensible table.

Frequently asked questions

What if my JSON isn't an array of objects?

The tool expects a JSON array where each item is an object; a single object or deeply nested structures may not convert cleanly.

What happens to missing fields?

If an object is missing a key that others have, that cell is left blank in the resulting CSV row.

Are commas inside values handled correctly?

Yes, values containing commas or quotes are automatically wrapped in quotes per standard CSV formatting.

Is my data uploaded anywhere?

No, the conversion happens entirely in your browser.
