## Data-Type Reference: `csv` 

> CSV files (and other character delimited tables)

## Description

This data type can be used for not only CSV files but also TSV (tab separated)
or any other exotic characters used as a delimiter.

## Detail

The CSV parser is configurable via `config` (see link below for docs on how to
use `config`)

    » config: -> [csv]      
    {
        "comment": {
            "Data-Type": "str",
            "Default": "#",
            "Description": "The prefix token for comments in a CSV table.",
            "Dynamic": false,
            "Global": false,
            "Value": "#"
        },
        "separator": {
            "Data-Type": "str",
            "Default": ",",
            "Description": "The delimiter for records in a CSV file.",
            "Dynamic": false,
            "Global": false,
            "Value": ","
        }
    }
