how to create percentage datatype in uipath
Percentage data type? Do you mean double data type?
If yes, then simply make the variable type to Double, if it’s not present you can browse for more types and search System.Double!
Do you mean to be able to save a value to Excel so that it shows % after opening the Excel file?
I do not think you can do it in UiPath unless you use a macro to set the format of the cell.
