Private, ad-free JSON workspace
Convert JSON into CSV, YAML, or XML without leaving the browser. The converter is useful when API data needs to become a spreadsheet-friendly export, a config format, or an XML handoff.

CSV is flat. Every row is a set of columns, with no room for an object inside a cell. JSON is not flat, so converting an array of nested objects means deciding how to represent that nesting. A common approach is to flatten nested keys into dotted column names, so an address object becomes address.city and address.zip. Arrays inside a record are trickier and usually get joined or expanded, which is worth checking on the output.
The cleanest input for a CSV conversion is an array of objects that share the same keys. That maps directly to a header row plus one row per object, which is what most spreadsheets and data tools expect.
YAML keeps the full structure of your JSON but swaps braces and quotes for indentation, which reads well in config files and documentation. XML wraps each value in tags, which is what older integrations and some enterprise systems still expect. Both preserve nesting, so they handle deep objects more directly than CSV does.
Conversion runs locally in the browser, so source JSON and converted output are not uploaded.
The converter supports CSV, YAML, and XML output from JSON input.
Nested JSON can require flattening or representation decisions for CSV because CSV is tabular. Review the output when converting deeply nested arrays or objects.
