How does CSV to YAML conversion work?

Each CSV row becomes a YAML list item starting with "- ". When "Use headers" is enabled, the first row defines keys and each subsequent row generates key: value pairs. Without headers, each row becomes a nested list of values.

What delimiter should I use?

Comma is the most common CSV delimiter. Semicolons are common in European locales where commas are used as decimal separators. Tab-separated values (TSV) use tabs, and pipe delimiters are used in some legacy systems.

How are special characters handled in YAML output?

Values containing YAML special characters (:, #, {}, [], etc.), newlines, or leading/trailing spaces are automatically quoted. Numeric-looking values and YAML keywords (true, false, null) are quoted to preserve them as strings.
