도구 개요
CSV remains the path of least resistance for moving tabular data between tools. This converter accepts a JSON array of objects (keys become column headers) or a JSON array of arrays (rows written as-is). Cells containing the delimiter, double quotes, or newlines are wrapped in quotes with internal quotes doubled, per RFC 4180. Nested objects and arrays are serialized back to JSON so they survive the round trip.
사용 사례

입력 의도
[{"id":1,"name":"Alice","role":"admin"},{"id":2,"name":"Bob","role":"user"}]출력 의도
id,name,role 1,Alice,admin 2,Bob,user
Cells containing the delimiter are automatically quoted (RFC 4180).

product,price,inStock "Widget, Blue",19.99,true Gadget,42,false
Nested arrays are serialized back to JSON inside the cell so nothing is lost.

자주 묻는 질문
Is this JSON to CSV converter free?+
Yes. Unlimited conversions, no sign-up, no row limit, and everything runs in your browser.
What shape must my JSON have?+
Either an array of flat objects (keys become column headers) or an array of arrays (each inner array is a row). Mixed shapes will produce a validation error.
How are nested objects or arrays handled?+
They are serialized back to a JSON string inside the cell so no information is lost. If you need one column per nested field, flatten the JSON first or pre-process with jq.
Does it escape fields with commas, quotes, or newlines?+
Yes. Cells containing the delimiter, a double quote, or a newline are wrapped in quotes with internal quotes doubled, following RFC 4180.
Can I output tab-separated or semicolon-separated values?+
Yes. Change the delimiter option to Tab, Semicolon, or Pipe — ideal for Excel in European locales or TSV workflows.
