UiPath Apps Filter do not support any advanced operation like OR and combination. This will return only all the matching result based on filter into AND condition.
UiPath VB Apps is coming soon and that will support OR and AND both condition.
=> Read the data from excel and save it to a data table say dt_input.
=> create a variable say dt_filtered of data type System.Data.DataTable.
=> Give the below condition in assign activity:
dt_filtered= dt_input.Select("Name = 'Artur' OR Country = 'Argentina'").CopyToDataTable()
=> you can print that in message box by converting the data table to string using Output Data Table actvitiy.
Check the below images for better understanding. Instead of excel I have taken data through build data table.
