});Comma-Separated Values (CSV, sometimes also called character-separated values, because the separator character may not be a comma), its file stores tabular data (numbers and text) in plain text. Plain text means that the file is a sequence of characters and contains no data that must be interpreted like a binary number. A CSV file consists of any number of records, separated by some kind of newline character; each record consists of fields, and the separators between fields are other characters or strings, most commonly commas or tabs. Typically, all records have exactly the same sequence of fields. Usually these are plain text files. It is recommended to use WORDPAD or Notepad (NOTE) to open it, and then save a new file first and then open it with EXCEL, which is also one of the methods. A universal standard for the CSV file format does not exist, but there is a basic description in RFC 4180. The character encoding used is also not specified, but 7-bit ASCII is the most basic universal encoding.
