One common use case for using JavaScript in Microsoft Power Automate RPA Developer is automating form submissions. JavaScript can be used to fill out and submit forms on web pages, making it ideal for automating repetitive tasks such as data entry.

To automate form submissions using JavaScript, you can leverage the capabilities of the Browser action in Power Automate RPA. The Browser action allows you to interact with web pages using JavaScript and perform actions like clicking buttons, filling in text fields, and submitting forms.

Here’s an example of how you can automate a form submission using JavaScript in Power Automate RPA Developer:


const form = document.getElementById('myForm');
const firstNameInput = document.getElementById('firstName');
const lastNameInput = document.getElementById('lastName');

In this example, we have a simple HTML form with two input fields for first name and last name, and a submit button. The JavaScript code uses the getElementById method to get references to the form and input fields. It then sets the values for the input fields and triggers the form submission using the submit method.

By combining this JavaScript code with the Browser action in Power Automate RPA, you can automate the process of filling out and submitting forms on web pages.

Scraping data from web pages with JavaScript in Microsoft Power Automate RPA Developer

Another useful application of JavaScript in Microsoft Power Automate RPA Developer is web scraping. Web scraping involves extracting data from web pages and is commonly used for tasks like data extraction, data aggregation, and content monitoring.

Using JavaScript in combination with the Browser action, you can navigate to web pages, locate specific elements, and extract data from them. The Browser action provides a set of JavaScript functions that can be used to interact with web page elements.

Here’s an example of how you can scrape data from a web page using JavaScript in Power Automate RPA Developer:


const pageTitle = document.getElementById('pageTitle').textContent;
const listItems = Array.from(document.querySelectorAll('#list li')).map(li => li.textContent);

console.log('Page Title:', pageTitle);
console.log('List Items:', listItems);


In this example, we have a simple HTML page with a heading element and an unordered list. The JavaScript code uses the getElementById function to get a reference to the heading element and the querySelectorAll function to select all the list items. It then extracts the text content of the elements and logs them to the console.

By incorporating this JavaScript code into your Power Automate RPA workflow, you can automate the process of scraping data from web pages and use the extracted data for further processing or analysis.

Performing calculations and data transformations with JavaScript in Microsoft Power Automate RPA Developer

JavaScript can also be used in Microsoft Power Automate RPA Developer to perform calculations and data transformations. Whether you need to manipulate numbers, convert data formats, or apply conditional logic, JavaScript provides a versatile and flexible solution.

You can use JavaScript’s built-in functions and operators to perform mathematical operations, manipulate strings, and implement conditional statements. By leveraging the Script action in Power Automate RPA, you can execute JavaScript code directly within your workflow.

Here’s an example of how you can use JavaScript for performing calculations and data transformations in Power Automate RPA Developer:


const num1 = 10;
const num2 = 5;

console.log('Sum:', sum);
console.log('Difference:', difference);
console.log('Product:', product);
console.log('Quotient:', quotient);
console.log('Reverse Name:', reverseName);


In this example, we have JavaScript code that performs basic arithmetic operations using two numbers (num1 and num2). It calculates the sum, difference, product, and quotient of the numbers. Additionally, it manipulates a string (fullName) by splitting it, reversing the parts, and joining them with a comma delimiter.

By integrating this JavaScript code into your Power Automate RPA workflow, you can easily perform calculations, manipulate data, and transform data formats based on your specific requirements.

In summary, using JavaScript in Microsoft Power Automate RPA Developer offers various use cases such as automating form submissions, scraping data from web pages, and performing calculations and data transformations. These examples demonstrate the power and versatility of JavaScript when combined with the capabilities of Power Automate RPA.
