FAQ
How are column types detected?
Numbers, booleans (true/false), and null are inferred automatically; everything else stays a string. Turn off type inference to keep every value as a string.
What happens if rows have different columns?
Converting JSON → CSV unions all keys across every object into the header row, leaving a blank cell for objects missing that key.
