Most online converters quietly mangle real data: they turn 007 into 7, drop a row whose comma count is off, or write a broken file when a value contains a comma or a quote. FlipCSV doesn't.
Handled honestly: values stay strings unless you opt into type inference, and even then 007 and 1e999 are left alone because converting them would lose information; CSV rows with the wrong field count are reported, never silently dropped; JSON → CSV quotes strictly to RFC 4180 and uses the union of every object's keys, so no field disappears because a later row introduced it.
