Question 1

How does the tool handle nested JSON objects?

Accepted Answer

Nested JSON objects are automatically flattened into CSV columns using dot notation (e.g., 'address.city'). This preserves all your data hierarchy while making it compatible with the flat CSV format. You can customize the flattening behavior as needed. Your files are processed entirely in your browser and never uploaded to any server.

Question 2

Can I convert in both directions — JSON to CSV and CSV to JSON?

Accepted Answer

Yes, the converter works both ways. You can convert JSON to CSV for spreadsheet use, or convert CSV back to JSON for use in APIs and applications. Simply select the direction and upload your file. Your files are processed entirely in your browser and never uploaded to any server.

Question 3

Is any data lost during conversion?

Accepted Answer

The converter preserves all data values during conversion. When converting JSON to CSV, nested structures are flattened with dot notation. When converting CSV to JSON, each row becomes a JSON object with column headers as keys. No data is lost in either direction. Your files are processed entirely in your browser and never uploaded to any server.
