.csv is a comma-separated values file that allows data to be saved in a table structured format. Traditionally they take the form of a text file containing information separated by commas, hence the name. It looks like a spreadsheet file but with a .csv extension.


.csv files can be used with any spreadsheet program, like Microsoft Excel, Open Office Calc, or Google Spreadsheets. They differ from other spreadsheet file types in that you can only have a single sheet in a file, they can not save cell, column, or row styling, and can not save formulas.


In eCommerce, .csvs are used primarily for importing and exporting product, customer, and order information to and from your store.
