If FILEs are not specified, csv2json reads its input from standard input and writes output to standard output; the output can be redirected to a file by -o option.
The first line in the input is expected to be a row containing a list of column names by default; this can be turned off by -N option. If column names are not included in the input, a list of default column names are generated which follow 'columnN' naming convention where 'N' is an integer and starts from 1.
If both short form and long form are specified on the command line, the long form will take precedence.

Prompt before overwriting the output file.
