Frequently Asked Questions

Can it handle nested JSON objects?

The tool flattens nested objects into CSV columns. For example, {user: {name: 'John'}} becomes a column named 'user.name'. Arrays are converted to comma-separated values within cells.

What if my JSON is an array of objects?

Perfect! That's the ideal format for CSV conversion. Each object becomes a row, and the keys become column headers. The tool automatically detects this structure.

Can I open the CSV in Excel?

Yes! The generated CSV follows standard formatting and can be opened directly in Microsoft Excel, Google Sheets, LibreOffice Calc, or any spreadsheet application.

What about missing fields in some objects?

The tool intelligently handles missing fields by leaving those cells empty in the CSV. It creates columns for all unique keys found across all objects in your JSON array.

Is this tool really free?

Yes! JSONToAll is completely free to use with no hidden fees, registration requirements, or usage limits. All processing happens in your browser, so we don't even store your data.
