Auto type-casting
When enabled, numeric strings become numbers, "true"/"false" become booleans, and empty fields become null. Disable it to keep all values as strings.
Why use CSV to JSON online?
CSV to JSON in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.
