Frequently asked questions

Does it handle quoted fields and commas inside values?

Yes. Quoted fields, escaped quotes and embedded delimiters are parsed properly rather than split naively.

What happens to nested JSON?

CSV is flat, so nested objects are serialised into their column. Flatten the data first if you need separate columns.
