Frequently Asked Questions
How does the converter handle nested JSON?
The converter flattens nested objects using dot notation. For example, "address.city" becomes a column header in the CSV.
What happens with JSON arrays?
Arrays are converted to pipe-separated values within a single cell. For example, ["red", "blue", "green"] becomes "red|blue|green".
Can I process large JSON files?
Yes! The converter is optimized for efficient memory usage and can handle large datasets. For very large files, consider using the command line version.
Is my data secure?
All processing happens in your browser. Your JSON data is never sent to our servers, ensuring complete privacy.
