How to Convert JSON to Excel Free — JSON to Spreadsheet Online

Why Convert JSON to Excel?

Developers work in JSON. Everyone else works in spreadsheets. When a manager asks for "the data in a spreadsheet," when a client needs a report they can open in Excel, or when you need to review API output visually — that's when JSON to Excel conversion saves you from writing export scripts.

How to Convert JSON to Excel

1. Open the JSON to Excel tool
2. Paste your JSON or upload a .json file
3. The tool maps JSON keys to column headers and values to rows
4. Download the .xlsx file

All processing happens in your browser. Your data is never sent to a server.

What JSON Structures Are Supported

• Array of objects — the most common format. Each object becomes a row, keys become column headers.
• Nested objects — nested properties are flattened with dot notation (e.g., "address.city" becomes a column)
• Simple arrays — arrays of values become single-column spreadsheets

The tool handles real-world JSON — API responses, database exports, config files — not just textbook examples.

Use Cases

• API data review — dump an API response into Excel for visual inspection
• Client reports — convert backend data to spreadsheets for non-technical stakeholders
• Data validation — review JSON datasets in a familiar spreadsheet format
• Backup exports — save JSON database exports as Excel files for archival
