⭐ JSON to Excel converter - explanation and examples

With JSON to Excel, you can quickly convert a JSON file into a structured XLSX workbook. The tool supports JSON arrays, single JSON objects, and objects with multiple datasets. Everything runs locally in your browser, with no server upload.

🔎 Which JSON structures are supported?

  • JSON array of objects: converted to one worksheet with columns based on all discovered fields.
  • Single JSON object: converted to one worksheet with one row.
  • JSON object with multiple arrays: each array is automatically exported to a separate worksheet.

⚙️ Data types, empty values, and nested fields

Numbers and booleans are preserved as much as possible. Dates can be exported as real Excel dates or kept as text. Nested objects and arrays are automatically stored as JSON strings in a single cell. For empty values, you can choose between an empty cell or the text null.

📊 Preview and validation before download

Before downloading, you get a preview of the first 10 rows, plus practical stats such as worksheet count, total rows, columns, and the final XLSX file size.

🧪 Example: JSON export to Excel for reporting

  1. Upload a JSON file with orders, customers, and products.
  2. Choose options such as date handling and auto-fit columns.
  3. Review the preview of the first 10 rows.
  4. Download your Excel file (.xlsx) for further analysis.
