Thta is good, I had this done so far, However now I have to tell excel that all the columns that will import will be text, because if for some reason I send a string lets say like '00001' excel converts it to 1, in order to avoid this I should tell in the import that specific columns will be text. I made a macro in excel and what it does is to send a string something like this

array(array(1,1),array(1,2)) the ,2 means it is text, ,1 it is general.

When I try to send this as a string the object class gives me and error, how do I do this
