My YAML to JSON conversion fails on indentation

YAML uses indentation to define nesting. Check for mixed tabs and spaces, inconsistent indent width, or list items that are aligned under the wrong parent key.

My JSON to YAML output looks different from the original style I want

conversion preserves data, not formatting preferences. Quotes, line breaks, and key layout may change when the parsed data is serialized back to YAML.

Comments disappeared after converting YAML to JSON

JSON has no comment syntax, so YAML comments are dropped during parsing and cannot be reconstructed later.

Anchors or aliases did not survive the round trip

YAML anchors and aliases are YAML-specific syntax sugar. After parsing, the converter keeps the resolved data structure, not the original anchor notation.

A value changed type unexpectedly

YAML parsers may interpret bare values like `true`, `false`, `null`, `42`, or `3.14` as booleans, null, or numbers. Quote them in YAML if you need them treated as strings.

My YAML uses `!!set` or `!!omap`

Those YAML-native collection tags do not have a clean JSON equivalent. Convert them to ordinary lists or mappings first, or expect the YAML-to-JSON path to report them as unsupported.

Round-trip note: YAML comments, anchors, aliases, quote style, and original formatting are not preserved after conversion through JSON.
