About CSV to JSON Converter
CSV looks simple until a value contains the delimiter. The convention is to wrap such values in double quotes and to escape an internal quote by doubling it, and a correct parser also has to allow line breaks inside a quoted field. This converter follows those rules rather than splitting on commas.
Watch for the classic conversion traps: leading zeros in identifiers, long numbers that lose precision, and dates in regional formats. Keeping those columns as strings is almost always the safer choice.
