This tool is useful in case you accidentally switch from offline mode to online mode, or vice versa, and you need to revert player data accordingly. This tool modifies only the file names. In the future, I might update it to modify files and databases as well.

It will create a backup of the modified files.

How to use:

• Download the jar and place it in your server folder (where the server jar is located).
• Double-click it to open the GUI, or use the following command to open it without a GUI:

• After you open it for the first time, it will create a folder called 'UUIDConverter'. Go there and open config.yml.
• After configuring it, open the jar again, follow the instructions, and you're done.

If you're encountering problems, send me the log files from the folder on my Discord: balustrada
I log into my Spigot account once every few weeks or months. You'll receive a much faster response if you DM me on Discord.
