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
- Open the JSON to Excel tool
- Paste your JSON or upload a .json file
- The tool maps JSON keys to column headers and values to rows
- 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
