You can use your Smartsheet data that resides in Sheets or Row Reports in an AppSheet app.
First, you need to use your Smartsheet account to sign into AppSheet. You can then build mobile apps using any of your data sheets or Row Reports. In fact, AppSheet is already aware of some Smartsheet-specific column types like Harvey Ball and Color. All AppSheet functionality works seamlessly with Smartsheet data.
An Appsheet table that is based upon a Smartsheet Row Report supports both update and delete. However, you cannot add new records to an Appsheet table that is based on a Smartsheet Row Report.
If you're a business customer of Smartsheet, the solutions team at Smartsheet can also help you with your AppSheet integration.
