JSON to Excel Converter for Browser-Based XLSX Export
This JSON to Excel converter turns a JSON array of objects into a downloadable Excel .xlsx file with SheetJS. If your input is a JSON object with top-level keys, enable multi-sheet mode to create one worksheet per key. The conversion runs in your browser, so you can generate a spreadsheet without installing software or sending your data to a server.
The JSON to Excel converter turns JSON data into a downloadable Excel .xlsx file using SheetJS. It is designed for JSON arrays of objects, and it also supports JSON objects with top-level keys when you enable multi-sheet mode. That option creates one worksheet for each top-level key, giving you a way to organize the resulting workbook by key.
To convert JSON to Excel, paste or enter your input and adjust the available option if needed. Use a JSON array of objects for a standard conversion. If your input is a JSON object with top-level keys, turn on multi-sheet mode to create a separate worksheet for each key. When the conversion is complete, download the generated .xlsx file.
JSON represents structured data, while Excel .xlsx files organize information in workbooks and worksheets. Converting JSON to Excel is useful when you want to work with supported JSON data in a spreadsheet rather than keep it in its original structured format. The multi-sheet option is available for top-level keys in a JSON object; it creates one sheet per key.
The conversion runs entirely in your browser, so your input is processed on your device and is not sent to a server. The tool is free and works offline once the page has loaded, which can help when you need to convert data without a network connection. It is useful for developers, DevOps engineers, and anyone who needs a browser-based way to create an Excel file from JSON without installing anything locally.
Step 1: Paste or enter your JSON input. Use a JSON array of objects for a standard workbook, or a JSON object with top-level keys if you want to use multi-sheet mode.
Step 2: Adjust the available option. Enable multi-sheet mode to create one worksheet for each top-level key in a JSON object.
Step 3: Start the conversion. The tool uses SheetJS to generate an Excel .xlsx file from your JSON.
Step 4: Download the generated file. You can then open the .xlsx workbook in a spreadsheet application.
