  5. JSON to CSV

JSON to CSV

Paste JSON data and convert it into CSV instantly for spreadsheets, exports, or quick data sharing.

How JSON to CSV Works

This page reads an object or array of objects, collects the keys it finds, and writes them as CSV headers. Each object then becomes one row, which makes the result easy to paste into spreadsheets or export-friendly workflows.

It is a practical tool for API samples, quick data cleanup, spreadsheet imports, and converting structured browser-side data into a tabular format.

Best Input Shape

The best input is a flat object or an array of flat objects with consistent keys. Nested objects and arrays inside values are possible to stringify, but they are usually harder to use in a normal CSV workflow.

If you need a cleaner spreadsheet export, flatten the data first so each field maps more naturally to one column.

How to Convert JSON to CSV

  1. Paste a JSON object or array of objects into the input area.
  2. Click `Convert to CSV`.
  3. Review the CSV output and copy it into your spreadsheet or export flow.

FAQ

What kind of JSON does this page accept?

It accepts one object or an array of objects. Those keys become CSV column headers.

What happens if objects have different keys?

The converter builds a combined header set from the keys it finds and leaves missing values blank where a row does not have a particular field.

Is this meant for deeply nested JSON?

No. This page is best for flat object data. Very nested structures are better flattened or simplified before converting to CSV.
