How do I convert JSON to Excel?

Paste your JSON data into the converter, choose Excel (XLSX) or CSV format, configure options like nested object flattening and array handling, then click Convert. Download the generated Excel file instantly - no account needed.

How do I convert JSON to XLSX?

Paste JSON data, select XLSX format, optionally enable nested object flattening for complex data structures, and click Convert to Excel. The tool generates an Excel spreadsheet file that you can download and open in Excel, Google Sheets, or any spreadsheet program.

Is this JSON to Excel converter free to use?

Yes, this JSON to Excel converter is completely free with no limits on the size or complexity of JSON data you can convert. No registration required, no watermarks added to generated files, and unlimited conversions.

Are my JSON files uploaded to your servers?

No, all JSON processing happens locally in your browser using SheetJS technology. Your data never leaves your computer, ensuring complete privacy and security for sensitive business information and API responses.

What JSON formats are supported?

Supports any valid JSON including objects, arrays, nested structures, and mixed data types. Works best with arrays of objects or single objects that can be converted to tabular format for Excel spreadsheets.

How are nested objects handled?

Nested objects can be automatically flattened using dot notation (e.g., user.profile.name). You can control the flattening depth and disable it to keep nested data as-is if preferred. Perfect for complex API responses.

What happens to arrays in the JSON data?

Arrays can be joined with a separator (default), separated into individual columns, or ignored. Choose the option that best fits your data structure and analysis needs when converting to Excel.

Can I export to CSV instead of Excel?

Yes, you can choose between Excel (.xlsx) and CSV formats. CSV is useful for importing into other tools and databases, while Excel preserves formatting and supports multiple sheets with better data type handling.

How are different data types handled?

Strings remain as text, numbers as numeric values, booleans as TRUE/FALSE, dates in configurable formats, and null values as empty cells or custom values based on your settings. Excel data types are preserved correctly.

What if my JSON has missing or inconsistent fields?

The converter handles missing fields gracefully by creating empty cells in the Excel output. Inconsistent structures are normalized, and all unique fields across objects become columns in the spreadsheet.
