I was please to see that I could edit my spreadsheet. I would suggest that once a work or set of numbers are highlighted that the program automatically is able to identify the font and size of the writing. Otherwise I was very pleased.

The outputs of the system are great ... just your opening page is a bit confusing. I just wanted to look convert a document but couldn't see conversion icons - finally worked out that I have to use Add New button - remember people are coming to your website from other portals they have used before - and like me they look for a document conversion tool!
