Web Scraping – Automate collecting tabular data from web page using Power Automate desktop

In this post, we will use Power Automate Desktop(RPA) and collect tabular data from web page.

What is Web scraping?

Web scraping is the process of using bots to extract content and data from a website. Unlike screen scraping, which only copies pixels displayed onscreen, web scraping extracts underlying HTML code. In this demo.

Introduction to Power Automate Desktop:

Power Automate Desktop broadens the existing robotic process automation (RPA) capabilities in Power Automate and enables you to automate all repetitive desktop processes. It’s quicker and easier than ever to automate with the new intuitive Power Automate Desktop designer using the prebuilt drag-and-drop actions or recording your own desktop flows to run later.

Before you begin, please make sure the following prerequisites are in place:

  • Power Automate Desktop installed and configured on your computer.
  • Install Power Automate Browser extension and configure the browser.
  • Working knowledge of the Power Automate desktop.
  • If you are planning to run the Flows in an attended or unattended mode, you need the on-premises data gateway for your device to have the desktop flow triggered by Power Automate.

Your boss wants to keep a track of the Gold Prices for everyday. You as an RPA manager need to automate the process using Power Automate Desktop.

For details see the screenshot below:


Step 4:

  • Add the ‘Create file‘ SharePoint action to create the PDF document in the SharePoint document library.
  • Folder Path: Specify the output path to write the PDF file to.
  • File Name: For this demo we will create the File Name ‘Gold Price Month-@{triggerBody()[‘number’]}.pdf’.
  • File Content: ‘Processed file content‘ is the output variable of the ‘Convert document‘ action.

All Done!  Start your Flow ‘Manually‘ and after a few seconds, the Power Automate Desktop should launch, scrap the data from the web page and a PDF document will be created in the destination library.
