problem while downloading to excel

Hi ABAPers,

Im using OLE to download entries from internal table to excel.

One of the entry in internal table is of length 18 i.e account no. = 123456789876543212,type c(18)

My problem is that when this entry get downloaded in excel it gets printed as exponent.

i.e1.23457E+17.

How can i print account no. in the same format.

please help.

thanks in advance.

regards,

Lokesh
