# Global Data

You can use global data to specify global variables in your workflow. For instance, you have several new tab blocks where the URL entry has the same domain, e.g., "<http://dribbble.com>". You can define the URL domain in the global data instead of modifying one block at a time to change the URL domain.

```json
{
  "url": "https://dribbble.com"
}
```

Then, you can access the global data inside the URL text field of the New Tab block using an expression. In our example, we used this: `{{globalData.url}}`
