Frequently Asked Questions
How does nested object flattening work?
Nested objects are flattened using dot notation (e.g., address.city). You can control the maximum depth and choose whether to flatten or stringify complex objects.
What happens to arrays in the JSON data?
Arrays of primitive values are joined with semicolons. Arrays of objects are JSON stringified to preserve the data structure.
Can I customize the CSV delimiter?
Yes, you can choose from comma, semicolon, tab, or pipe delimiters based on your requirements and regional formatting preferences.
What if my JSON has inconsistent structures?
The tool automatically detects all unique keys across all objects and creates columns for each. Missing values are left empty in the CSV.
Is the conversion process secure?
Yes, all processing happens in your browser. Your JSON data is not sent to any server, ensuring complete privacy and security.
