CSV File Definition:
DEFINITION 1: A CSV file is commonly described as a 'Comma Delimited File' or a 'Character Separated File'. The second description is more accurate since any character including the comma, can be used to delineate each piece of data. For example, a TSV file, 'commonly known as a 'Tab Delimited File', is really just a special case of a CSV file. Since a CSV file is a simple text file (ASCII or Unicode) it can be easily opened by Notepad.exe which is included in all versions of MS Windows. A typical CSV file, where a comma is used to distinguish each record, looks like this in Notepad.exe:
Name1,Address1,Telephone1
Name2,Address2,Telephone2
Name3,Address3,Telephone3
Name4,Address4,Telephone4
Or if the "|" bar character is used to separate the data, it might look like:
Name1|Address1|Telephone1
Name2|Address2|Telephone2
Name3|Address3|Telephone3
Name4|Address4|Telephone4
DEFINITION 2: A CSV file is a text file that has a specific format which allows for the saving of textual information/data in an organized fashion. The format, known as a flat table, is very simple. Each row (paragraph) contains one record of information; each record can contain multiple pieces of data (fields) each separated by a character. The character used to distinguish each piece of data within each record is most commonly a comma, but can be any character.
