The CSV library provides functions related to comma separated values.
Functions
csv:from_array(<entry array>, <field array>)
Formats a CSV string from and array of maps.
This function takes an array of maps representing the entries to be formatted and an array with the desired fields.
If the field array is missing, all the fields in the maps will be returned.
The function assumes that each of the maps in the array have the same keys.
