IconVault's JSON to CSV converter turns structured JSON data into a clean CSV spreadsheet in one click, and converts CSV back to JSON just as easily. Paste an array of objects and get properly quoted, escaped comma-separated values with the headers as the first row, ready to open in Excel or Google Sheets, or download the result directly.

The converter handles the tricky parts: nested objects are flattened with dotted paths, values containing commas or quotes are escaped per the CSV spec, and round-trips preserve your data types. Conversion happens fully in your browser with nothing uploaded, so private datasets stay private, and it is free to try (heavy repeated use may ask for Pro).
