About This Calculator
This JSON to CSV converter reads a JSON array of objects and produces a comma-separated table with a header row.
Column headers are the union of all object keys in the array; each object becomes a row, with missing keys left blank and nested values stringified. The output is fully quoted per CSV rules, so Excel, Google Sheets, and databases import it cleanly. Change the delimiter to semicolon, pipe, or tab for locales that use those formats.
Conversion happens entirely in your browser — your data never leaves your device.

Frequently Asked Questions
Does the order of columns matter?
No. Columns come from the union of keys across all objects, in first-seen order. Rows are output in the same order as the array.
How are nested objects handled?
Nested objects and arrays are converted to their JSON string form inside the cell. For fully flattened output, pre-flatten the JSON first.
