Using Sharepoint column format to show button for files only using JSON

Question

I have added the following JSON code to sharepoint to show a button to request document approval, however I want to limit this to only show the button against files not folders using the Boolean IsFolder.

However I am really new to all of this and cannot work out what expressions I need to add to implement this filter.

Any and all help would be great!

Answer 1

You can hide the button for folders based on Content Type like:

"style": {
    "visibility": "=if([$ContentType] == 'Folder', 'hidden', 'visible')"
}

OR

"style": {
    "display": "=if([$ContentType] == 'Folder', 'none', 'block')"
}

You can refer to this JSON sample which uses same expression to hide the button for folders: Download File Button
