Common QA use cases
Test data often lives in spreadsheets (CSV) but APIs expect JSON. Convert your test fixture CSV directly to JSON arrays ready to POST to your API. Going the other way, convert a JSON API response into CSV to share with a product manager or import into Excel for analysis.
The converter handles RFC 4180 quoted fields correctly — values containing commas, quotes, or newlines are preserved through the round-trip conversion.
