Does it handle quoted fields with commas and newlines?

Yes. It's a real RFC 4180 reader, not a split on commas — quoted fields, embedded commas, doubled quotes, and newlines inside quotes all parse correctly. That's the difference between a converted file and a silently corrupted one.

What happens to a short row?

Missing trailing fields become empty strings rather than undefined, so every record has the same keys.

What if a quote is never closed?

It errors instead of guessing. A silently truncated field is worse than a message.

CSV to JSON

Turn a CSV (or TSV, ; and | files) into a JSON array of records — headers become keys.

Worked example

Input

name,age
Ada,36
Al,41

Output

[
  {
    "name": "Ada",
    "age": "36"
  },
  {
    "name": "Al",
    "age": "41"
  }
]

This example is one of CSV to JSON's test cases — if the tool stopped producing this output, the build would fail.
