Frequently Asked Questions

How to convert JSON to Excel online?

Simply paste your JSON data into the input area, and our converter will instantly generate a live Excel preview. You can then download the Excel file in XLSX, XLS, or CSV format. The conversion works with arrays of objects, nested data, and complex JSON structures.

What JSON structures can be converted to Excel?

Our JSON to Excel converter supports all JSON data types: arrays of objects (ideal for spreadsheet rows), nested objects with automatic flattening, primitive arrays, and complex hierarchical data. The live preview shows exactly how your JSON will appear in Excel format.

How are nested objects handled in JSON to Excel conversion?

Choose between two conversion modes: Flatten nested data (default) creates separate columns with dot notation (e.g., 'user.address.city') and indexed arrays (e.g., 'items[0].name'). Non-flatten mode preserves nested structures as JSON strings in Excel cells.

What Excel formats are supported for JSON conversion?

Convert JSON to multiple Excel formats: XLSX (modern Excel), XLS (legacy Excel), CSV (comma-separated values), and ODS (OpenDocument). All formats maintain data integrity and support custom headers and sheet names.

Can I preview JSON data before converting to Excel?

Yes! Our JSON to Excel converter includes a live table preview that shows exactly how your data will appear in Excel. The preview uses Excel-style column names (A, B, C...) and updates automatically when you change conversion settings.
