Extracts the specified columns of the CSV document.

##

### [JavaScript]

    document.ExtractColumns( strColumns );

### [VBScript]

    document.ExtractColumns strColumns

## Parameters

strColumns

Specifies the string to select which columns to include in the output document. This value is a combination of columns separated by commas. Each column can be either the first line of the column or a colon (:) followed by the index of the column. For example, ":1,:3" will output the first and third columns of the active document, and "first_name,last_name" will output the column whose first line matches "first_name" or "last_name". Use '+' instead of ',' to concatenate with the previous column, and '|' to use the first non-empty value.
