Learning Robotic Process Automation

By: Alok Mani Tripathi

Overview of this book

Robotic Process Automation (RPA) enables automating business processes using software robots. Software robots interpret, trigger responses, and communicate with other systems just like humans do. Robotic processes and intelligent automation tools can help businesses improve the effectiveness of services faster and at a lower cost than current methods. This book is the perfect start to your automation journey, with a special focus on one of the most popular RPA tools: UiPath. Learning Robotic Process Automation takes you on a journey from understanding the basics of RPA to advanced implementation techniques. You will become familiar with the UiPath interface and learn about its workflow. Once you are familiar with the environment, we will get hands-on with automating applications such as Excel, SAP, Windows and web applications, screen and web scraping, working with user events, and we'll cover exceptions and debugging. By the end of the book, you'll not only be able to build your first software robot, but you'll also wire it up to perform various automation tasks with the help of best practices for robot deployment.

Choose the specific area from which you want to extract the text from the image. In our case, we are using an image that we have searched for on Google.

  1. Now, click on the Text property of the Get OCR Text activity. A window will pop...
