Common errors

The input is not valid JSON

Fix: Validate the JSON first and remove trailing commas, single quotes, or broken brackets.

The user expects comments to be preserved from the source

Fix: JSON does not support comments, so only the actual data structure can be converted.

Nested objects look different than expected in YAML

Fix: Remember that YAML uses indentation instead of braces and brackets to represent structure.
