Dalek, the option is to read PDF in your code written in Java or C# (or some other .NET language). Then you can present the PDF data as some text you can import in Excel or directly create an excel file using Microsoft Office interop
, in this case its better to use .NET (well, in all cases it's better to use .NET, just some people would prefer Java
). Apparently, another input should be some mapping rules you want to apply when generating output.
Why did I mentioned just Java and .NET? Because of the most recommended product called iText for Java, see http://en.wikipedia.org/wiki/IText
There is also a .NET port called iTextSharp, see http://sourceforge.net/projects/itextsharp/
I believe you can find out from MSDN how to work with Excel in .NET. How about that?
