Your app can also display external URLs, documents, and audio files.
AppSheet supports two data types for external content: URL and File. If you have URLs in a column, the app allows users to click on the URL and see the content in a hosted web browser window. Additionally, the users have the option of opening the content externally in the native web browser on the device (such as mobile Safari on iOS).
If you have files in a File column, the app opens the content in a hosted web browser. Depending on the device and operating system, there may be support for viewing a variety of file types-- for example, most browsers enable PDF viewing and playback of MP3 audio files.
To include files or PDFs in your app, you will need to add either the file name or the URL where the document is hosted. if you are using URLs, make sure they are publicly accessible by placing them in a public folder.
