About

JSON to CSV Converter is a free online tool that transforms JSON data into spreadsheet-ready CSV files entirely in your browser. Paste raw JSON, drag and drop a file, or fetch data from a public URL. The converter automatically flattens nested objects using dot notation, lets you choose your delimiter (comma, semicolon, tab, or pipe), and includes smart cell quoting to keep your data intact.

You get an interactive table preview where you can sort columns, search rows, and adjust pagination before exporting. The tool supports JSON arrays of objects and single root objects, handles files up to tens of megabytes, and works with Excel, Google Sheets, Pandas, and SQL. All parsing and conversion happens locally in your browser memory.

The editor includes syntax highlighting with dark and light themes, line numbers, and instant JSON schema validation. Download your CSV with one click, and your data never leaves your computer.

100% client-side processing means your data never touches a server. No account creation, no row limits, no paywalls. The tool automatically flattens nested JSON hierarchies into clean dot notation, offers multiple delimiter options with smart quoting, and provides an interactive table preview for inspection before export.

Problem: Converting JSON from APIs and databases to CSV for spreadsheets is tedious. Many converters require accounts, hide features behind paywalls, or send sensitive data to remote servers.
Solution: This free converter runs entirely in your browser, flattens nested data automatically, lets you choose delimiters, and shows a preview before you export. Your data stays private on your computer.
