What this tool does
JSON to CSV flattens JSON arrays and objects into a CSV table you can open in any spreadsheet. It turns a list of records into rows and columns, so data that came back from an API becomes something you can sort, filter, and share without writing a parser.
How it works
Paste your JSON or open a file, and the tool converts it to CSV in your browser. Review the table and copy or download it. Nothing is uploaded.
When to use JSON to CSV
