JSON Formatter vs YAML Validator
Use JSON tools for strict API-style payloads and YAML tools when human-edited config readability matters more.
JSON wins when strictness is useful
JSON is intentionally rigid, which makes a formatter and validator ideal for APIs, fixtures, and machine-generated payloads where ambiguity is the enemy.
If the job is to catch syntax problems fast and keep structure predictable, JSON tooling is often the simpler path.
YAML wins when humans edit the file often
YAML is more comfortable for many configuration workflows because comments and visual structure matter more there. A YAML validator is useful when the input is hand-edited and indentation mistakes are the real pain point.
Choose by the system you are feeding
If the destination expects JSON, stay there and validate early. If the destination is a config stack that speaks YAML naturally, validate indentation and structure instead of forcing everything through JSON first.
