Should CSV numbers always become JSON numbers?
Not necessarily. A value such as `00123` may be an identifier rather than a quantity, so automatic type conversion should be reviewed.

Frequently Asked Questions
What happens if the CSV has no header row?
The converter needs another way to determine property names, or the output may be better represented as a two-dimensional array.

It turns flat records into structured objects that can be consumed more naturally by application code and APIs.
Does it support Tab-separated TSV files?
Yes, you can choose Tab, Semicolon, or Pipe delimiters.
