How to select the past date from excel reading data to web application

How to select the past date from excel reading data to select the calendar date picker in web application
Example:
Given input data from excel as MM/DD/YYY = 15/08/2018

You use the Excel activities (Use Excel File, Read Range, etc) to get the Excel data into a datatable. Then you work from the datatable. Assuming you need to loop through the rows then you use For Each Row in Datatable.

To put the date into the date picker, that all depends on the date picker. Does it have a box where you can type the date? If so, then just use Type Into.

Post a screenshot of it.

Also, I suggest doing the free training on the UiPath Academy web site. Lots of good stuff there, and it covers things like what you’re trying to do.
