What is CSV?

CSV (Comma-Separated Values) is a simple text format for storing tabular data. Each line represents a row, and values are separated by a delimiter (usually comma).

Example CSV

                                    Name,Age,City
John,30,NYC
Jane,25,LA
                                

Key Concepts

Rows

Each line in a CSV file represents one record (row) of data.

Columns

Values separated by delimiters form columns. Each column typically represents one attribute.

Header Row

The first row often contains column names that describe the data below.

Delimiters

The character used to separate values. Most common is comma, but can be semicolon, tab, or pipe.

Common Issues

All values are text. CSV has no data types - numbers and dates are stored as plain text.

Quoting matters. If a value contains the delimiter, it must be enclosed in quotes.

Encoding issues. CSV files can have different text encodings (UTF-8, ASCII, etc.).
