Invoice(char column) with number 01 appears 1 in Excel

 Hello All,

There is a custom report , it’s output type is XML

Everything is OK except that

 

I have a column in the report called “invoice or check number” it is a character column in the RDF file

The issue I have :

 there is an invoice number 01  but it appears 1  not 01  

Whereas in the XML source ,it appears  01  

Also in the RTF file, it appears  01

When I generate Excel , it appears 1  

Find attached files please , they illustrate what I explain

Could anyone guide me how to fix this issue ,please?

Thanks
