CSV Data


As can be seen in the above example, each row is a new line, and each column is separated with a comma. Many online services such as an online bank allow its users to export tabular data from the website into a CSV file. These files can then be opened and viewed offline using a spreadsheet program such as Microsoft Excel.

Why are CSV files used?

There are two primary reasons CSV files are used online.

  1. CSV files are plain-text files, which makes them easy for the website developer to create.
  2. Because the CSV is plain-text it makes the data easy to import into any spreadsheet program or database regardless of what type of computer or software program you are using.
