Free JSON to Excel Converter

JSON is the language of APIs and modern data exchange, but when you need to analyze, share, or present that data, a spreadsheet is usually the better format. Our free JSON to Excel converter transforms JSON data into clean CSV files that open perfectly in Excel, Google Sheets, and any spreadsheet application. Just paste your JSON or upload a JSON file, and the tool flattens nested structures, maps keys to column headers, and arranges values into rows — producing a spreadsheet that is ready for analysis. The converter handles various JSON structures: arrays of objects (the most common API response format), nested objects, arrays within objects, and mixed data types. Each conversion is intelligent — nested keys are flattened using dot notation (e.g., address.city becomes a column header), arrays are expanded into separate rows or comma-joined values depending on the structure, and data types are preserved. Whether you are working with API responses, database exports, configuration files, or any other JSON data, this tool gets it into spreadsheet format in seconds.
