Camel JSON to Excel

Convert JSON to Excel online — no signup, no upload, no limits. Paste a JSON array of objects or drop a .json file, and download a formatted .xlsx spreadsheet. Object keys become column headers, each object becomes a row. Nested objects are flattened with dot notation. Numbers and dates are stored as proper Excel types so sorting and formulas work correctly. Everything runs locally in your browser.

What JSON format does it accept?

The tool accepts a JSON array of objects — the most common format from APIs and databases. Each object becomes a row, and each key becomes a column header. Nested objects are flattened with dot notation (e.g., address.city).

Does it handle nested JSON?

Yes. Nested objects are flattened into dot-notation columns. For example, {"user": {"name": "Alice"}} becomes a column named "user.name". Arrays within objects are stringified.

Can I upload a JSON file instead of pasting?

Yes. Click the drop zone or drag a .json file into it. The file is read locally and parsed — it never leaves your device.

Is there a row limit?

No hard limit. The tool runs in your browser, so it depends on available memory. Tens of thousands of rows typically work fine.
