How do I convert a JSON file to XLSX?

Upload your .json file or paste JSON text into the input area. Set optional flattening options for nested objects and arrays, then click 'Convert'. The tool parses your JSON and generates a downloadable .xlsx file with keys as column headers and values as rows. Open it in Excel, Google Sheets, or LibreOffice Calc.

Why convert JSON to XLSX instead of keeping it as JSON?

JSON is great for storing structured data and APIs, but it's not designed for human tabular analysis. XLSX lets you filter, sort, and create pivot tables in Excel. Converting JSON to XLSX also makes data easier to share with non-developers and integrates with business reporting tools.

How does the converter handle nested objects and arrays during JSON to XLSX conversion?

Nested objects are flattened using dot notation (e.g., 'address.city'), and arrays are either expanded across rows or merged into a single cell as comma-separated values, depending on your settings. Primitive types like numbers, booleans, and nulls are preserved natively in XLSX; ISO date strings are auto-converted to Excel date cells, and duplicate keys get a numeric suffix to keep columns unique.

Is JSON-TO-XLSX free to use?

Yes, JSON-TO-XLSX on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?
