What file format is commonly represented as a comma separated value?

The commonly recognized file format represented as a comma-separated value is CSV. This format is specifically designed for the storage of tabular data, where each row represents a record and each column's value is separated by a comma. CSV files are widely used for data exchange between applications that may not support more complex types of data formats, making them an ideal choice for handling simple datasets in a human-readable form.

The simplicity of CSV files allows them to be easily edited in text editors and imported into spreadsheets or databases without requiring complex coding or parsing. While other formats like TXT (which is simply a text file) could potentially contain comma-separated values, they are not specifically recognized as CSV. XLSX is an Excel-specific format, and XML is a markup language suited for data representation that supports hierarchical structures rather than simple tabular data, making them less ideal for this particular context.
