    },
    "title": {
      "text": "My Advancement"
    },

      "text": "Earn this custom advancement."
    },

  },
  "criteria": {
    "requirement": {
      "trigger": "minecraft:impossible"
    }
  }
}

The minecraft:impossible trigger never completes on its own — you grant the advancement only via the /advancement command.

About custom advancements

Advancements are datapack-defined tasks players can earn, described by triggers and criteria. This tool produces the JSON content you place in data/<namespace>/advancement/<name>.json (the singular 'advancement' folder on Java Edition 1.20.5+). Titles and descriptions are safely escaped into JSON automatically. Everything runs entirely in your browser.
