How Excel to CSV Conversion Works

Spreadsheet exports

CSV and TSV exports contain plain rows and columns.

One table

CSV usually exports one table at a time.

Rows

Each table row becomes a CSV row.

Cells

Each cell becomes a CSV field.

Delimiters

A delimiter separates fields in each row.

Quotes

Quotes protect delimiters and line breaks inside values.

Tables, Headers, Delimiters, and Encoding Explained

Source

Headers

Header rows are normal rows unless excluded.

Comma

Comma is the most common CSV delimiter.

Semicolon

Semicolon is common in some spreadsheet regions.

Tab

UTF-8

UTF-8 supports a broad range of characters.

Colours, fonts, borders, and styles are not stored in CSV.
