JSON to CSV FAQs
What is a JSON to CSV converter?
A JSON to CSV converter turns JSON objects or arrays into rows and columns that spreadsheet tools, databases, and reporting workflows can import.
Can this converter flatten nested JSON?
Yes. When flattening is enabled, nested object keys become dot-notated columns such as user.name or usage.requests.
Are my JSON files uploaded?
No. The conversion runs in your browser, so pasted JSON is not uploaded to Code Card by this tool.
What JSON shapes work best for CSV?
An array of similarly shaped objects works best because each object becomes a row and each unique key becomes a column.
Can I use semicolon or tab-delimited output?
Yes. Choose comma, semicolon, or tab as the delimiter before copying or downloading the generated CSV.
