Sharepoint JSON - display a button if two columns exist

Anonuser1981 

Which version of SharePoint you are using? You can use [$Owner.title] != '' to check if Owner field is empty or not.

If you are using SharePoint online, use below JSON code for your requirements. If you are using SharePoint 2019 then convert this in AST format using the above condition for Owner field:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "button",
  "txtContent": "Get Approved",
  "customRowAction": {
    "action": "executeFlow",
    "actionParams": "{\"id\": \"6ff70d5d-977d-42c4-8989-41c6c9fc16b2\"}"
  },
  "style": {
    "background-color": "#004B8B",
    "padding": "10px 10px",
    "border": "2px solid white",
    "text-align": "center",
    "font-size": "12px",
    "color": "white",
    "display": "=if([$Status_value] == 'Pending' && [$Owner.title] != '', 'block' , 'none')"
  }
}

Note: You need to use internal name of Status_value and Owner column in JSON.
