How does it handle nested JSON objects?
Our tool attempts to flatten simple nested structures (e.g., address.city becomes a column 'address/city'). For complex arrays within objects, it safely stringifies the inner data so you don't lose any information.
Can I convert large JSON files?
Yes! Since we don't upload your file to a server, the limit is only your browser's memory. You can typically convert files up to 100MB-200MB without issues.
Why are some characters quoted?
CSV requires fields containing commas, newlines, or quotes to be wrapped in double quotes. Our tool complies with RFC 4180 standard to ensure the CSV opens correctly in Excel.
