How to remove the Bold Font in MS Text

Dear Team


My request would be
If I transfer the Microsoft Text file to PB LUX 5. Unfortunately if I open the file it shoves a lot of bold text, and so if that happens, I have to scroll to the net page, and to the next. It shows only 1 bold font sentence.
How can I remove the bold text, so that the file contains instead of, for example 50 site, just 20 sites.

Thanks a million
I love your products
