CSV file
CSV = Comma Separated Values (also: Character Separated Values)
A CSV file is a text file for storing or exchanging simply structured data.
The file extension is .csv.
Example: Source table with numerical values:
value 1.0 value 1.1
value 2.0 value 2.1
value 3.0 value 3.1
This results in the following CSV file:
value 1.0;value 1.1;value 1.2;value 1.3
value 2.0;value 2.1;value 2.2;value 2.3
value 3.0;value 3.1;value 3.2;value 3.3
