JSON to CSV Converter

JSON to CSV Converter is a web tool that turns JSON data into CSV files. It runs completely in the browser, so the user’s data never leaves the computer. The tool accepts JSON pasted directly, uploaded as a file, or fetched from a public URL, and produces a CSV that can be opened in spreadsheet programs. The interface shows the JSON with syntax highlighting and lets the user choose a delimiter such as comma, semicolon, tab, or pipe. Nested objects are automatically flattened using dot notation, for example user.address.city becomes a separate column. A live table preview lets the user sort, search, and page through rows before downloading the final CSV with one-click. The converter is most useful for developers, data analysts, and anyone who needs to move data from APIs or JSON exports into Excel or Google Sheets. Because it works offline and supports large files, it fits into daily data-cleaning workflows without requiring installation or an account.
