About JSON to CSV

The JSON to CSV Converter turns a JSON array of objects into comma-separated rows you can open directly in Excel, Google Sheets, or any spreadsheet. Each object becomes a row and each property becomes a column, with a header row generated automatically from the keys. Conversion runs entirely in your browser, so even private data stays on your device. You choose the delimiter, and nested values are flattened sensibly. Need the reverse? Use the CSV to JSON converter.

Frequently Asked Questions

How are nested objects and arrays handled?

Nested values are flattened into columns using dotted key paths so the tabular output stays readable. Deeply nested arrays are serialized into a single cell so no data is lost during conversion.

Can I choose a different delimiter?

Yes. Comma is the default for standard CSV, but you can switch to semicolon or tab if your spreadsheet locale or target tool expects a different separator.

Is JSON to CSV free to use?

Yes. JSON to CSV is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use JSON to CSV?

Absolutely. JSON to CSV runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
