Convert JSON data into CSV format instantly.

About JSON to CSV

Spreadsheets still power business decisions. When you receive JSON arrays from an API or export, convert them to CSV for Excel, Google Sheets, or LibreOffice - directly in the browser without uploading sensitive rows to a third party. Map nested fields where supported, preview output, and download CSV ready for pivot tables and mail merges. Perfect for analysts, support teams, and founders who need quick visibility without writing scripts. For large datasets, modern desktops handle substantial JSON locally; keep confidential exports on trusted machines only.
