1Before converting

  • Keep the source file and confirm its encoding and data format.
  • Check whether the first row contains headers and whether field names look correct.
  • For personal or sensitive data, confirm where processing happens and who will receive the output.

2After converting

  • Use the preview to verify text, column names, and row counts.
  • Open the result in Excel or the destination system and check dates and long numbers.
  • Save the converted file under a new name so it can be compared with the source.

What is JSON to Excel Converter?

This tool turns JSON arrays, API responses, and database exports into Excel-ready .xlsx files. Nested objects are flattened into dot-notation columns for easier spreadsheet review.

Review API JSON in Excel

Each item in a JSON array becomes a row and object keys become Excel columns. This makes API responses and database exports easier to review without writing a conversion script.

Nested objects are flattened into columns such as user.name, while arrays are preserved as JSON strings.

Supported JSON structures

  • Arrays of objects
  • A single JSON object
  • Nested objects
  • Data containing strings, numbers, booleans, and null values

How JSON values map to Excel

Arrays
