What kind of JSON does this page accept?
It accepts one object or an array of objects. Those keys become CSV column headers.
Paste JSON data and convert it into CSV instantly for spreadsheets, exports, or quick data sharing.
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.
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.

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

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