Democratizing Application Development with AppSheet

By: Koichi Tsuji, Suvrutt Gurjar, Takuya Miyai

Overview of this book

Many citizen developers regularly use spreadsheets in their business and day-to-day jobs. With AppSheet, you can take your spreadsheets to the next level by enhancing their ease of use. The platform allows you to run your business efficiently and manage it in the field outside of an office or indoor environment. This book enables you to create your own simple or medium to complex hybrid apps for business or personal use. As a beginner to AppSheet, this book will show you how the AppSheet Editor works and how it is used to configure, test, and deploy an app and share it with others as users or co-authors. You’ll learn about widely used features such as how to use data sources, create app views and actions, construct expressions with AppSheet functions, and make your app secure through security and UX options. Next, you’ll create email/attachment templates and develop reports/documents based on templates, store in the cloud, and send files through emails. You’ll also understand how to integrate third-party services and monitor various usage statistics of your app. As you progress, you’ll explore various features with the help of sample apps that you create using the book. By the end of this book, you’ll have learned how to make the most of AppSheet to build powerful and efficient applications.

Using multiple functions in single expressions

So far, we have mostly concentrated on understanding various AppSheet functions. Most of the expressions we have used have mainly been based on single functions. You can combine various functions in a single expression to come up with more complex logic requirements in your apps.

We will learn about complex expressions based on some use cases and associated expressions to see how we can combine multiple functions in a single expression:

Table 4.49 – Using multiple functions in complex expressions – 1

Let us learn another expression that combines three functions of IN(), TOP(), and ORDERBY() in a slice filter expression to filter rows based on certain criteria:

Table 4.50 – Using multiple functions in complex expressions – 2

You can configure much more complex expressions involving multiple functions in your app. However, it is always a better approach to configure...
