RPA stands for Robotic Process Automation,  an emerging form of business process automation technology which provides easy GUI based tools and activity to automate business processes.
Here we are using UiPath RPA Tool.
Simple Hello World and Web Scraping Projects/Program articles are already here in C# Corner.
Now we will create Automation using UiPath to read the data from the existing Excel file and paste that data into Notepad.
Type Name and Description then click on the Create button
 
Step 2
 
As this is a very simple step first we will be reading an excel then we will open a notepad and write the invoice number into it. So we will choose Sequence activity as everything is in linear/sequence form.
 
 
Click open main workflow
 
Drag sequence activity under main
 
 
Change properties displayName from Sequence to “Read Excel and paste into notepad”

For reading an excel first we will choose the activity called "Excel Application Scope" from activities
 
Type "Excel application scope" into search activities
 
 
 
Drag it into "drag activities here" under main
 
Give the Excel path in WorkbookPath Properties or else just click … and browse to the Excel file.
 
  
Search Read Excel and drag it as below: 
 
 
 
Now give the cell value and Sheet name from an existing Excel sheet as below
  
 
To store a result we need a variable
