Frequently Asked Questions

How does the converter handle nested JSON?

Nested objects are flattened using dot notation. For example, {address: {city: 'NY'}} becomes a column header 'address.city' with the value 'NY'. Arrays within objects are joined with semicolons.

Can I open the CSV output in Excel?

Yes, the generated CSV files are fully compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and any other spreadsheet application.

What if my JSON has inconsistent keys across objects?

The converter handles this gracefully by creating columns for all unique keys found across all objects. Missing values in objects without certain keys are left as empty cells.
