描述

Hi there, I have a stream JSON of data which I would like to unparse and stream to a csv file. I see in the documentation we are able to parse from a stream but is the other way supported?

Thanks!

研究方向
Investigate the existing streaming parser implementation in PapaParse (likely in src/PapaParse.js or similar). Check if there are any linked discussions or prior attempts. The feature would require implementing a writable stream that converts JSON to CSV, similar to the existing readable stream for parsing. Look at the library's API for unparse to understand the serialization logic.
