REPLACE '#' WITH ' '

Hi Experts,

i hope you can help me. I have to upload an excel sheet by FM 'TEXT_CONVERT_XLS_TO_SAP'. The result that i get contains a string that could implement line breaks. This line breaks are each identified by '#'.

Before the string is displayed the '#' has to be replaced. I have tempted it with

REPLACE '#' WITH ' ' but i get no positiv result.

Can anyone assist me to resolve this problem?
