Introduction
A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values.
CSV file stores tabular data (numbers and text) in plain text. Each line of the file is a data record.
Each record consists of one or more fields, separated by commas.
The use of the comma as a field separator is the source of the name for this file format.
How do you open them?
