A CSV file, or comma-separated values file, is a type of plain text file that stores tabular data in a structured format. Each line of the file represents a row of data, and the values in each row are separated by commas. CSV files are often used to store data that is exported from databases or other software programs.
CSV files are relatively easy to create and read, which makes them a popular choice for data exchange. They can be opened and edited using a variety of software programs, including spreadsheets, text editors, and database programs.
