Need to convert JSON to Excel without writing a script? Paste a JSON array or object above, preview the rows, and download a real .xlsx spreadsheet in seconds. The converter works with API responses, exported records, configuration data, and JSON files.
This JSON to Excel converter generates an actual .xlsx workbook — not a CSV file renamed with an Excel extension. It opens cleanly in Microsoft Excel, Google Sheets, and Numbers, with each JSON key becoming its own column. Everything runs client-side in your browser, so your data is never uploaded to a server.
Real-world JSON is rarely flat. This tool automatically flattens nested objects into dot-notation columns — a field like address.city becomes its own column with the nested value — and joins nested arrays into a single readable cell, so you still get one clean row per record instead of a broken or truncated sheet.

Nested objects are automatically flattened into dot-notation columns (e.g. address.city), and nested arrays are joined into a single readable cell, so the sheet stays flat and Excel-friendly.
No — the conversion happens entirely in your browser using JavaScript. Nothing is sent to a server.
