YAML relies on indentation for hierarchy, so indentation spaces cannot be completely eliminated.

Questions

Frequently Asked Questions

Can YAML be minified like JSON?

YAML cannot be made into a single line without using JSON-like flow syntax ({a: 1}), but minification removes comments and extra blank lines.

Does minifying YAML strip comments?

Yes, all comment lines starting with # are stripped.
