@luis.espeleta  You need to add a LOT more information if you expect help. Is this number matrix in an application? A browser? What have you tried on your own? Where are you running into problems/errors? Help us help you. 

Hi @luis.espeleta.

You can try using two recorders in Automation 360, the Universal Recorder and the AISense Recorder, to automate tasks by recording interactions with objects such as click, read and write.

Hope this helps!

@luis.espeleta, can you please explain your scenario in detail.
