prevent Excel from converting string to exponential notation

I'm downloading a dataset from a website.  The first column has parcel numbers, which are actually strings not numbers.

Sometimes, if there is an "E" in the parcel number, Excel reads the value as a number in exponential notation.

Two examples:

0060A-0014 gets read in correctly (as left justified text).

0063E-0010 gets read in incorrectly as 6.30E-09 (numeric, right justified). 

How can I fix this?  Excel breaks the data as it is reading the file and I don't know how to fix it.

Better yet, how can I prevent it?

Thanks,

Doug
