How to Convert JSON to CSV

Drop or paste an array of objects — the typical shape of API responses and exports.

Object keys become column headers and each object becomes a row, right in your browser.

Open the result in Excel or import it anywhere CSV is accepted.

✓API responses become Excel-friendly tables

✓Handles mixed keys across objects

✓Quoted and escaped output per CSV standard

✓100% local — API data stays private

What JSON shape is expected?+

An array of objects like [{"name":"Ann","age":30}, …]. Keys become the header row; each object's values fill one row.

What happens with nested objects?+

Nested values are serialized into their cell as JSON text. For deeply nested data, consider restructuring in code first — CSV is inherently flat.

Do all objects need the same keys?+

No — the converter collects the union of all keys and leaves cells blank where an object lacks a value.

Why convert JSON to CSV?+

To open API data in Excel, hand it to non-technical colleagues, or import it into tools that only accept spreadsheets.
