In Control rule validator

Choose the Minecraft version and filename, paste the complete file, and select Validate. The tool checks JSON syntax, duplicate fields, known settings, value types, and several common rule mistakes.

New to rule files? Read the In Control getting started guide. Validation catches many mistakes, but the installed mod and its log remain the source of truth for version-specific behavior.

Results

Paste your file and select Validate. Errors and warnings are listed here, and the editor reformats your file when it parses.
