About YAML and JSON
- YAML is a human-friendly config format – used by Docker Compose, Kubernetes and GitHub Actions – that uses indentation instead of brackets and quotes.
- JSON is the data format of web APIs and JavaScript apps: records with named fields, which can be nested inside each other.
Tips for Chromebook

Frequently asked questions
Do I need to write code to convert YAML to JSON?
No. Paste or drop the file and the converted version appears straight away – no scripts, libraries or terminal.
How big a file can it handle?
Files of several megabytes convert in a moment. There's no fixed limit; the only constraint is your device's memory.
