A CSV file itself requires no installation as it is just a plain text file, usually with .csv
extension.
A CSV file usually contains records. Each line represents one record and is separated by a delimiter, most commonly a comma; but semicolons and tabs are also frequently used. Each line should have the same number of fields.
example.csv:
Name,Age,Skill,Height,Friendly
Bob,22,10,6.3,yes
Frank,12,7,5.5,no
