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": ","
    }
}
