What is a CSV File?
TL;DR: CSV (Comma-Separated Values) is the simplest tabular data format — plain text where each line is a row and values are separated by commas. It's universally supported by spreadsheets, databases, programming languages, and data tools.
CSV files have no formatting, formulas, or charts — just raw data. This simplicity is their strength: any software can read CSV, making it the standard format for data exchange between systems. Fields containing commas or newlines are wrapped in double quotes.
