We are designing system which would allow you to automate your business flows. To process all that information we need to be able to process documents of different types. When we looked at Aspose components, the first thing I noticed was its well-built API. It's intuitive, clear and well documented. Also, it is amazing at reading 'edge-case' documents (i.e. documents with some specific version of format or non-trivial documents). It allows you to process many different file formats, including images, Visio diagrams, Outlook mail, OneNote, GIS files, and - except for a few cases - performance is very fast. The components are self-sufficient, requiring no other external dependencies, and they do indeed parse the document according to format specification. I'd recommend Aspose as one of the best components for documents processing
