I don’t currently have a public app with this functionality, but essentially it’s just a URL that you place in a column and view as a link in the app. So essentially you can create a dynamic PDF view of one of your sheets without opening up google sheets. For example, I’ve included two links that point to the NotesDetails sheet in my Concepts app. The first link creates a PDF, but the second link opens a Google Docs viewer to view the spreadsheet. The PDF and Viewer both show data that’s currently on the sheet as of the time you open the link. If you look closely at both links you can see the SpreadsheetID and the SheetID (gid) are part of the URL.
