Thank you for your response, @Fiat Lux - ASIA 

Do I need a 3rd party program to only do this conversion one time?  Meaning, I had outside help assist in entering numerous vendors and invoices, as I continued with my daily on the main QB profile on my computer.  This won't be a regular occurrence of needed to merge the files, I just need to add what she has entered on the second computer into my main QB Desktop program.  Thank you in advance!
