02 / what you get
What happens to your data
Kept
- A list of mappings becomes the records, with the keys of each mapping as fields
- Anchors and aliases are resolved, so repeated values are written out in full
- A clean Excel workbook with one sheet, where plain numbers are real numeric cells you can sum and sort
Good to know
- Only one YAML document per file is supported; a file with several documents separated by --- fails.
- Comments are not part of the data and are dropped.
- The result is plain values on one sheet named Sheet1. There are no formulas, styles, column widths or charts.
- Nested objects and lists cannot sit in a table cell, so they are written into the cell as JSON text, for example {"city":"Lviv"}.

YAML vs XLSX
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.

XLSX
An XLSX file is a modern Excel workbook: sheets of cells with numbers, text, formulas and formatting. It is the default for spreadsheets today. Converting it gives you the first sheet as plain data (JSON keeps every sheet), so other tools can read it.
Used in: Excel · Business reports · Financial data
