How to use bukkit.yml, spigot.yml and paper-global.yml editor?

Paper servers generate bukkit.yml, spigot.yml, config/paper-global.yml and config/paper-world-defaults.yml on first start. This editor analyzes the file you paste, flags common YAML mistakes and lets you change the most useful keys with help and the documented default value.

  1. Pick the file to edit from the list.

  2. Paste your file's content (or import it). Nothing is sent to a server.

  3. Fix the reported problems (tabs, indentation, duplicate keys).

  4. Change the known keys in the table, then download the file and replace it on the stopped server.
