I think we can use GetText activity with proper selector. Probably we can use colName attribute.
So can you try to use UiExplorer then indicate target cell?
Or, as another approach, it’s also good to use DataScraping.
First use data scraping to get the table and then read the len of the firs row first column using dt.rows(0)(0).tostring and calculate the length .And i am not sure where you want to click but if the element tou want to click is spied then use click else try anchor base by using find element as anchor and then base as click
I managed to use data scraping and have the data extracted into a table but somehow, the data in the excel file seems to differ from the data in data scraping.
From the datascrapping you will get the datatable output just send that output to read range . As @Yoichi pointed build datatable is not needed. You just need to add retrieved data to excel if you want to.
