Minecraft Whitelist / Ops Generator
Paste a list of Minecraft usernames. We look up each UUID via the official Mojang API and generate the exact whitelist.json or ops.json file your server needs.
Add Players
UUIDs fetched from the official Mojang API. Invalid usernames are flagged but kept so you can fix them.
Generate whitelist.json / ops.json for Your Server
Paste a list of Minecraft Java Edition usernames — one per line, separated by commas, or space-separated. The tool queries the Mojang API for each and returns the UUIDs, then builds the exact JSON format your Minecraft server expects.
Supports both whitelist.json (allowed players list) and ops.json (server operators with permission levels 1-4). Invalid usernames are flagged but kept visible so you can fix typos before exporting.
Drop the generated file into your server root folder (overwriting the existing one if present), restart the server, and all listed players are whitelisted or opped. Works on Vanilla, Paper, Spigot, Forge, Fabric — any Java Edition server.
