This looks like it’s a mainframe. You need to use UiPath.Terminal.Activities and connect with Direct Connection (easier than using a third party client).
Then you can use the terminal activities to work in this app, get text from the screen, etc.
use the Get Screen Area activity to get all the text in that whole square section of the screen, into a string variable
split on VbCrLf to break it into an array of rows
loop through the array of rows
– break up each row into the individual columns, usually by length for a mainframe screen ie first column is the first 10 characters, next column is 2 characters, third column is 25 characters, etc
– Add data row into a datatable
That’s how you’d take the raw text from the screen and break it up into a proper datatable.
