How to convert JSON to CSV

  1. Choose a JSON file containing an array of records.
  2. Review the CSV preview and its column headers.
  3. Download the .csv file for use in spreadsheet software.

The input must be a JSON array of flat objects. Nested objects and arrays are serialized as JSON text in their cells.

FAQ

Are my spreadsheets or documents uploaded?

No. Data conversion runs locally in your browser. The selected files and results are not sent to our servers.

What are the data file limits?

Input files are limited to 15 MB and tabular or text data to 100,000 rows. PDF text extraction is limited to 200 pages. Scanned PDFs are not processed with OCR.

What JSON structure can I export to a table?

CSV and Excel exports expect a JSON array of flat objects, such as [{"name":"Alex","score":7}]. Nested objects and arrays are preserved as JSON text within a cell.
