Validate JSON before you ship a config change
Catch syntax errors early; pair validation with review for semantic correctness.

Key takeaways
- A validator catches malformed JSON fast.
- Schema checks (elsewhere) still matter for allowed fields and types.
Why validate early
CI and servers will reject bad JSON—catching issues locally saves churn.
Large files are painful to eyeball; validation gives a binary pass/fail signal quickly.
Escaping strings for APIs
When embedding arbitrary text inside JSON strings, JSON String Escape helps avoid quoting mistakes.
FAQ
Does valid JSON mean the config is correct?
It means parseable. Business rules still require schema tests or staging rollout.
What about trailing commas?
JSON forbids trailing commas—your editor may hide them until runtime fails.
