Separator comma and point in datatable

I use activity read range from excel and create data table. In one of coulmn from excel i take data type percent, and t
when it saved in datatable it look like a “data,data,4.20”. After that i used typeinto for the last column in my aplication. Uipth paste it as “4.20”, but my app is realy very old, and don’t undarstand if i use point for separate. Whats why i need paste “4,20” in app (separator - comma)

I see two different way

1- when i create data table it must be comma in table after copiyng from excel
2- when i using typeinto uipath changing point to comma

I dont how i can do this(

For #2, just use Replace to change the . to a ,

yourVar.Replace(".",",")
