How to import requirement text and tags as plain text rather than HTML?

I am trying to import an excel document to build requirements. When I import the table, all of the information that I am importing are being imported as HTML. I need this information to be in Plain Text instead. How can I do this?

Alternatively, if it is possible to change all the fields to plain text on mass, that would also work. I just have too many requirements to be able to manually change each one to plain text individually. 

Thank you!
