How to add data to the place where the cursor is set?

Question

.NET

I wrote a program that reads data from the serialport and adds it to the DataGridView and then saves it on the server. Now a condition has been added under which it is necessary for the program to work in the background and add the received data to the excel cell. How does a barcode scanner work? Please tell me how to start solving this problem. I don't even know how to approach it. Thanks

If you need to do this not with your external program, but directly in Excel , you can get by with the capabilities of VBA macros.
If you write your own program to work in the background, you need to write it as a windows service . Well, then write their own code into some Excel file in some of the many possible ways.
