The Universal Language: CSV
The CSV (Comma-Separated Values) format is the simplest, most universal way to store tabular data. Imagine a giant digital spreadsheet where each row is one unique board position and the columns contain information like the FEN string, the best move, and the engine's evaluation score.
CSV’s strength is its human readability and simplicity. Anyone can open it with a basic text editor or spreadsheet program. It is the perfect starting point for students to understand how data is organized into rows (records) and columns (fields) before they tackle more complex structures.
