CSV stands for Comma-Separated Values. It’s a simple text file format used to store tabular data (like a spreadsheet). Each line in a CSV file represents a row, and each value within a row is separated by a comma. This makes
them incredibly easy to read and process by humans and computers alike. Think of it as a structured way to organize information, perfect for transferring data between different applications.
Key Features of CSV Files
CSV files are characterized by their simplicity and widespread compatibility. Key features include:
- Simplicity: Easily readable and understandable by both humans and machines.
- Compatibility: Supported by almost all spreadsheet software (Excel, Google Sheets, LibreOffice Calc) and programming languages (Python, R, etc.).
- Portability: Easily transferable between different systems and applications.
- Efficiency: Relatively small file sizes compared to other formats like XLSX.
