comma-separated values (CSV) file contains the values in a
table as a series of ASCII Text lines organized so that each
column value is separated by a comma from the next column's
value and each row starts a new line.
CSV files are used to collect the data from any table so
that it can be used as input to another table-oriented
application. A Microsoft Excel spreadsheet application
or a relational database application can read CSV files. A
CSV file is sometimes referred to as a flat file.
