02 / what you get
What happens to your data
Kept
- The first row is used as the header and empty lines are skipped
- The separator is detected for you (comma, semicolon, tab or pipe), so exports from regional Excel versions work
- Quoted cells that contain separators, quotes or line breaks are read correctly
- A readable YAML list where each record is an item and each field is a key
- Plain numbers become YAML numbers; values like 007 stay quoted text
Good to know
- Values arrive as text and become numbers only where that is unambiguous and the target can hold numbers.
- Dates and numbers that were text are quoted where YAML would otherwise change their meaning, such as '007'.

CSV vs YAML
CSV
A CSV (Comma-Separated Values) file stores tabular data as plain text — each line is a row, commas separate the columns. It's the most universal way to move spreadsheet data between programs: Excel, Google Sheets, databases, and most apps can all read it.
Used in: Excel & Sheets exports · Database exports · Data sharing
YAML
A YAML file stores structured data in a clean, indentation-based format designed to be easy for humans to read and write. It's the go-to format for configuration files, so you'll often need to edit or convert one when setting up developer tools.
Used in: Docker · CI/CD pipelines · Kubernetes configs
