In multi-user applications, ensuring that each individual has access only to their relevant data is crucial for privacy and efficiency. AppSheet offers a powerful feature to achieve this personalized experience: slices combined with the USEREMAIL() function. This tutorial will explore how to set up user-specific data views in your AppSheet applications.

The Importance of User-Specific Views
Offering personalized data views not only enhances user experience by filtering out irrelevant information, but it also adds a layer of security and data privacy, ensuring users access only the data meant for them.
Prerequisites
- An AppSheet account and a basic app setup.
- A data source connected to your AppSheet app that includes user email addresses or identifiers.
1. Understanding Slices
Slices in AppSheet allow you to create subsets of your data based on specified conditions. These slices can then be used throughout your app to display filtered data.
2. Using the USEREMAIL() Function
The USEREMAIL() function retrieves the email address of the current user. This can be used as a condition in your slice to filter data specific to the user.
-
- Navigate to the Data Section: In your AppSheet editor, go to the “Data” tab and select “Slices”.
- Create a New Slice: Click on “New Slice”, give it a name, and select the table you wish to filter.
- Define the Slice Condition: Use the
USEREMAIL()function in the row filter condition to match the user’s email with the email field in your data. For example:[Email Column] = USEREMAIL() - Save and Use the Slice: After configuring your slice, use it as the data source for your app views to ensure users only see data that matches their email address.
Implementing the Slice in Your App
Once your slice is created, you can apply it across various features in your app, such as:
- Tables and Lists: Display only the records relevant to the logged-in user.
- Forms: Ensure users can only add data to their subset of the dataset.
- Dashboards: Create personalized dashboards that display data relevant to each user.
- Regularly Update Email Lists: Keep the email or identifier list in your dataset current to ensure data views remain accurate.
- Test Thoroughly: Verify that the slice correctly filters data by testing with different user accounts.
- Consider Privacy and Security: Always consider the implications of data access and ensure you’re compliant with privacy laws and regulations.
Conclusion
Creating user-specific views in AppSheet using slices and the USEREMAIL() function is a powerful way to personalize your app and enhance data security. By following the steps outlined in this guide, you can ensure that each user has a tailored and secure app experience, accessing only the data that is relevant to them.
