Frequently Asked Questions

What JSON formats are supported?

The tool supports JSON arrays of objects and single objects. For best results with CSV conversion, use an array of objects where each object has the same keys.

How are special characters handled?

Special characters like commas, quotes, and newlines are properly escaped. Values containing delimiters or quotes are wrapped in double quotes, and quotes within values are escaped.

Can I convert nested JSON to CSV?

Nested objects and arrays are converted to JSON strings within CSV cells. For complex nested structures, consider flattening your JSON first.

What delimiters are supported?

The tool supports comma (,), semicolon (;), and tab (\\t) delimiters. Choose the delimiter that matches your CSV file format or regional settings.

What is the table view?

When converting JSON to CSV, the output is displayed as a formatted table by default. You can switch to text view to see the raw CSV data. Table view makes it easier to visualize and verify your data.

Can I upload files directly?

Yes! Click the "↑ Upload File" button to select a .json or .csv file from your computer. The file content will be loaded into the input area automatically.

Is my data secure?

Yes! All conversions and file processing happen entirely in your browser. Your data never leaves your device and is not sent to any server.
