Understanding ParseJSON in PowerApps

In today’s data-driven world, handling JSON data is crucial for many applications, including those built with PowerApps. The ParseJSON function in PowerApps allows you to parse JSON-formatted data and work with its properties efficiently.

What is ParseJSON?

The ParseJSON function in PowerApps parses data in JSON format and creates untyped objects. This enables you to extract and manipulate data from JSON responses received from RESTful Web APIs or other sources.

Enabling ParseJSON Feature

To enable the ParseJSON feature in PowerApps.

1. Open your app in PowerApps Studio.
2. Click on Settings in the top bar of the screen.
3. Select Upcoming Features and then choose Experimental Features.
4. Search for "Parse" in the search bar.
5. Enable the ParseJSON feature.

How to Use ParseJSON?

Assume we have a JSON payload like the following.

{
    "name": "John",
    "age": 30,
    "car": null
}

Let’s break down how we can extract values from this JSON using ParseJSON.

Example

Assuming a Text Input control where the JSON is entered.

To display the name and car values.

Text (ParseJSON(TextInput1.Text).name)
Text (ParseJSON(TextInput1.Text).car)

To get the age as a numeric value.

Value(ParseJSON(TextInput1.Text).age)

In this example

• We use ParseJSON to parse the JSON input from the Text Input control.
• We then access specific properties like name, car, and age and display them using PowerApps Controls.

This approach allows you to integrate JSON data seamlessly into your PowerApps applications, enabling powerful data manipulation and presentation capabilities.

Conclusion

The ParseJSON function in PowerApps is a powerful tool for handling JSON data within your applications. It allows you to easily parse JSON-formatted responses from RESTful Web APIs and extract specific properties into your app’s interface. By enabling the ParseJSON feature in PowerApps Studio and using it with controls like Text Input and Labels, you can efficiently integrate JSON data into your application workflow.

Remember to carefully handle data types when using ParseJSON. Use functions like Value() for numeric conversions and ensure proper error handling for cases where JSON structure might vary or contain unexpected values.

With the ability to parse JSON and manipulate its contents dynamically, PowerApps empowers developers and users alike to create responsive and data-driven applications seamlessly.
