JSON Column Formatting in Sharepoint based on an address field

GeoffersThere is no direct way but you can always use a workaround. Like shown below

Step 1: Create a Calculated Column And add the formula which checks the Address is empty or not. Like shown below: (I am making sure address should have a postal code)

Step2: Then use that column to check if the Address is present then show or hide the button on the basis of Calculated column.

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "span",
  "style": {
    "color": "#0078d7",
    "background-color": "White",
    "visibility": {
      "operator": "?",
      "operands": [
        {
          "operator": "==",
          "operands": [
            "[$CheckAddress]",
            "Present"
          ]
        },
        "visible",
        "hidden"
      ]
    }
  },
  "children": [
    {
      "elmType": "span"
    },
    {
      "elmType": "button",
      "txtContent": "Send Mail",
      "customRowAction": {
        "action": "executeFlow",
        "actionParams": "{\"id\": \"e290feff-0013-41f2-97dd-91a37fb84ea0\"}"
      }
    }
  ]
}
