What's the difference between YAML and JSON?

YAML uses indentation and avoids brackets/quotes for simplicity, supports comments, and uses 'null' vs '~'. JSON is more explicit with brackets and quotes, widely used in APIs. Both are valid data interchange formats.

Why does my YAML conversion fail with 'bad indentation'?

YAML is whitespace-sensitive. Common issues: mixing tabs and spaces, inconsistent indentation depth, or unquoted strings containing colon-space (: ) which YAML interprets as key-value pairs.

Can I convert YAML with anchors and aliases?

The converter handles basic anchors (&anchor) and aliases (*alias). Complex merge keys (<<: *alias) may not fully resolve. Test with a simple example first.

Why are my quotes or special characters preserved differently?

JSON is stricter about quotes. YAML's output may add or remove quotes based on content type. For exact round-trip conversion, use the same tool consistently.
