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
- Pretty-printed JSON that any programming language can read
- Dates written as 2026-01-15 stay as readable text
- Nested objects and lists keep their structure.
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.
- Anything around the records in the source file (wrapper elements, comments, metadata) is not carried over.
03 / formats
YAML vs JSON
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
JSON
A JSON (JavaScript Object Notation) file stores structured, nested data as readable text — objects, arrays, and key-value pairs. It's the standard format for web APIs and app configuration, so you'll often get one from a developer, an API response, or an app's settings export.
Used in: Web APIs · App configs · Settings exports
