The JSON to CSV Converter transforms JSON arrays of objects into comma-separated values (CSV) format, automatically extracting all unique keys as column headers and flattening nested objects into dot-notation column names. JSON is the universal data interchange format for APIs and web services, while CSV is the most widely supported format for spreadsheets (Excel, Google Sheets) and data analysis tools (Pandas, R, Tableau). This browser-based tool handles nested structures, mixed-type arrays, and special characters with proper CSV quoting and escaping.
