How to Format and Convert JSON

Add JSON, CSV, or a text export from an API, database, or analytics tool.

Format, minify, validate, convert JSON to CSV, or convert CSV back to JSON.

Use the output in code, spreadsheets, documentation, or QA reports.

Format unreadable API JSON so fields, arrays, and nested objects are easier to inspect.

Convert an array of objects into CSV headers and rows for spreadsheet review.

Minify JSON before placing it in fixtures, examples, embeds, or lightweight configs.

Compare two JSON versions after formatting them.

Create QR codes from URLs stored in JSON or CSV campaign exports.

Build final PDF packets after exporting structured reports.

Is my JSON uploaded?

No. JSON and CSV text are processed locally in your browser.

Can this convert JSON to CSV?

Yes. Arrays of objects can be converted to CSV with headers.

What JSON input works best?

Valid JSON objects and arrays work best. For JSON to CSV, an array of similar objects gives the cleanest table.
