A CSV is a comma-separated values file, which allows data to be saved in a tabular format. CSVs look like a garden-variety spreadsheet but with a .csv extension. CSV files can be used with most any spreadsheet program, such as Microsoft Excel or Google Spreadsheets. They differ from other spreadsheet file types because you can only have a single sheet in a file, they can not save cell, column, or row. Also, you cannot not save formulas in this format.

In the world of online commerce, one of your main objectives is to reach a large number of clients.

  • The CSV format is documented in an RFC memo RFC-4180.
  • The first line is often the header, or column names. Each subsequent row is a record and should have the same number of fields.
  • Fields containing the separator character, line breaks and double-quotes must be enclosed inside double quotes ".
  • Other separator are often used like tabs \tor semi-colons ;. TSV or Tab Separated Values is used to store table data in Clipboards. When data is copied from Excel for example, it is stored as TSV in the Clipboard.
  • With CSVJSON you can parse values as numbers or JSON. Turn on respective Parse Numbers and Parse JSON switches to convert valid numbers and JSON (null, false, true, [] and {}).

It is referred to as a lightweight data-interchange format. It is self-describing and easy to understand. CSV is abbreviated as Comma Separated Value.
