JSON to Excel: Export JSON Arrays to Spreadsheet Format

Convert JSON to Excel format by exporting as CSV. Works with nested JSON objects, arrays, and custom delimiters. Opens directly in Excel and Google Sheets.

Convert JSON to Excel in 3 Steps

Excel cannot open JSON files natively, but it reads CSV files perfectly. Converting your JSON array to CSV and opening in Excel is the fastest way to get JSON data into a spreadsheet.

  1. Paste your JSON array into our JSON to CSV tool
  2. Click Download CSV
  3. Open the downloaded .csv file in Excel, Google Sheets, or Numbers

Why CSV Instead of .xlsx?

CSV is a universal format that all spreadsheet applications open natively. XLSX files require specific library support. By exporting CSV, we ensure compatibility with Excel 2007+, Google Sheets, LibreOffice Calc, Apple Numbers, and any data analysis tool.

Handling Nested JSON for Excel

Excel's flat structure doesn't naturally accommodate nested JSON. Our converter automatically flattens nested objects using dot notation (address.city) so every piece of data fits into a spreadsheet column.

Best Practices for JSON to Excel

  • Keep all objects in the array with the same structure for clean column headers
  • Avoid deeply nested arrays — they become complex to flatten into rows
  • Use the semicolon delimiter for European locale Excel (comma is decimal separator)

Frequently Asked Questions

Can I open the JSON2X CSV output directly in Excel?

Yes. Click Download CSV and the file opens directly in Excel with columns auto-populated from your JSON keys.

Does Excel support nested JSON?

Not natively. Our converter flattens nested objects using dot notation (e.g., address.city becomes a separate column), making it compatible with Excel.

What delimiter should I use for European Excel?

European locale Excel uses semicolon (;) as the CSV separator because the comma is the decimal separator. Select semicolon delimiter in our tool before downloading.

Can I convert to .xlsx format directly?

Our tool exports CSV, which Excel opens natively. For true .xlsx output, import the CSV into Excel and re-save as .xlsx.
