JSON to Excel
JSON to Excel is a free online converter that turns JSON data into Excel (.xlsx) spreadsheets in one click. Nested JSON is automatically flattened into columns and arrays become rows, preserving the field structure for data analysis and reporting.
All conversion happens locally in your browser — your data is never uploaded to a server. No sign-up or installation required, making it ideal for developers, data analysts, and operations teams working with API responses or log data.
How to Use
- Paste JSON text or upload a .json file
- Preview the parsed table structure and verify the fields
- Click "Convert" to generate the Excel file
- Download the .xlsx file
