YAML Config Checker
Check Minecraft YAML configs for tabs, odd indentation, duplicate keys, unbalanced quotes, and suspicious lines before restarting a server.
Check YAML Config Risk
This checker catches common YAML mistakes before a restart: tabs, odd indentation, duplicate key paths, unbalanced quotes, and lines that do not look like list items or key/value pairs.
If your server already failed, paste the error into the console error explainer or startup log classifier.
Safe Config Workflow
Back up the file, make one change, check the YAML, restart cleanly, and watch the first startup error. Avoid editing live configs from multiple panels at once.
FAQ
Is this a full YAML parser?
No. It is a fast browser-side risk checker for common Minecraft config mistakes. Always test important changes on a staging copy.
Why are tabs bad in YAML?
YAML indentation should use spaces. Tabs often trigger parser errors in plugin configs.
