How often do you have to take a spreadsheet data and covert to a character separated value? Tabular data, be it a number or a text are all stored in a plain text form by CSV (Comma Separated Values) files. A CSV file can compile a number of records with separate fields, which are uniquely identified by a standardized literal comma, tab, any character or string. This type of file format has been widely supported and used in many fields. All types of spreadsheets and database management systems basically support these CSV files.
