I use a company to receive packages in the United States and then ship them to me in another country. They require a copy of the invoice for customs and will accept the invoice in various formats, such as: PDF, DOC, DOCX, XLS, XLSX and others. When I go to this company's website to check if I can possibly get by with a Cut/Copy/Paste, the message that I get is: "Selecting Files Not Supported". I'm using a Logitech Revue. Is there an application of some sort whereby I could cut/copy/paste an invoice and have it converted to one of the acceptable formats? How about Open Office?
