What is CSV File Format?

A CSV (Comma-Separated Values) file is a commonly used format for storing tabular data, resembling a spreadsheet or database. It consists of data separated by commas, where each row represents a record. CSV files can be opened in text editors like Microsoft Notepad or Apple TextEdit, as well as spreadsheet programs such as Microsoft Excel or Apple Numbers.

When opened in a text editor, CSV data is displayed in a table format. Columns are separated by commas, and each row is separated by a new line. The first row, known as the header row, contains column names.

CSV files allow for easy data exchange between different applications. Data can be exported from spreadsheet programs like Excel or Numbers and saved in a CSV format. Similarly, CSV files can be imported into these programs, allowing data to be transferred from one system to another.

CSV files offer flexibility and compatibility due to their simple and universal structure. They are widely used for data migration, sharing information across platforms, and integrating data from various sources. The straightforward nature of CSV files makes them accessible for data manipulation, analysis, and processing by both humans and computer systems.
