CSV stands for Comma Separated Values. It’s a simple text file format that stores tabular data (like a spreadsheet) with each value separated by a comma. Think of it as a very basic, easily-readable database. Each line represents a row, and each comma separates a value within that row. This makes them highly compatible across various applications
and platforms.
Why use CSV files?
CSV’s simplicity makes it ideal for data exchange between different programs. Spreadsheets, databases, and even programming languages can easily read and write CSV files. Its straightforward structure minimizes compatibility issues, unlike more complex formats.
