How to Import Excel Errors as cell value and not as error? (=+keyword instead of #NAME?)

Hi all,

I have a weekly search keyword report that I want to upload to PowerBI via excel.  For some reason some keywords have a + in front of the word.  For example, +keyword.  Excel then automatically converts this cell to be =+keyword

Excel then goes a step further to show the cell as a name error (#NAME?).  When I import this file, Power BI classifies these values as 'Errors'.  Is there a way I can have Power BI import the cell as =+keyword and then I can clean the data within my Power BI query rather than having to clean the excel file prior to upload each week?

Thanks!
