Convert JSON arrays of objects into CSV format with automatic header extraction and proper escaping.
How to Use JSON to CSV Converter
The JSON to CSV Converter is a free online tool that transforms JSON arrays of objects into properly formatted CSV data. Paste your JSON array and the tool automatically extracts all unique keys as column headers, then maps each object to a CSV row with correct value escaping for commas, quotes, and newlines. Whether you are exporting API response data to a spreadsheet, converting database query results for analysis in Excel, preparing data for import into another system, or transforming structured data for reporting purposes, this tool handles the conversion instantly in your browser. It supports nested values by stringifying them and handles missing keys gracefully with empty fields. No data is sent to any server — all processing happens client-side for complete privacy and security of your data.
