SSIS package failed due to hidden characters in Excel source file (flat file)

I am experiencing an issue with failing my SSIS package due to hidden characters sits in some of the Excel columns. Some cells in the excel spreadsheet column are blank and they have some hidden characters that might cause this failure to transfer data from Excel flat file to SQL database. When I manually clear those empty cells package will work with no issues. So I want to find a way to clear those columns/cells that have hidden characters

If someone can help me on this would be much appreciated.

Thanks Heaps
