Hi @Ramon03 ,

I'm afraid it is not supported to to create a button in the list using JSON column formatting to open attachements in SharePoint Online.

When using Button elements in your JSON code, Button elements can be used to launch a specific action on the parent item. Every button element has a required property, customRowAction, that specifies an action that's taken when the button is clicked. This action must be one of the following values:

• defaultClick
• share
• delete
• editProps
• openContextMenu
• executeFlow

Please take a reference to this article and the article contains detailed description of the function of each value: button elements. The action property is set as below in the JSON formatting code of the delete button.

"customRowAction": {  
    "action": "delete"  
  }  

However, the action values such as opening attachments are not provided currently. As a result, it is impossible to open the attachment via a button using JSON formatting. As an alternative, you can build your SharePoint Framework (SPFx) Extensions to inject CSS/JS code to the list to achieve your requirement.
