A CSV file (Comma-Separated Values) is a simple text file that stores tabular data (numbers and text) in a comma-separated format. CSV files are commonly used to import and export data between different software applications, such as spreadsheets, databases, and statistical packages.
CSV files are relatively easy to create and can be opened and edited with a variety of software programs. To create a CSV file, simply open a text editor (such as Notepad or TextEdit) and enter your data into the file. Each line of the file should contain one row of data, with the values separated by commas.
