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 values within each row are separated by commas. This makes it easy to import and export data between
different applications, such as spreadsheets (Excel, Google Sheets), databases, and programming languages. Think of it as a very straightforward way to organize information in a table-like structure.
