This  article is about my views on Spire.doc which I tried for development  purposes on my personal site. Now, I would like to discuss a few points  about it. Recently, I came across a tool for .NET developers  named Spire, which has more features and is an easy GUI interface tool  for clients. E-ICEBLUE has a large number of tools and helps developers   a lot with different streams like .NET, Windows Presentation  Foundation, and Silverlight. E-ICEBLUE also helps in providing customer  support towards all products for their clients.

I tried using Spire.Office for my developments on .NET and WPF.
- Helps in opening all the file formats.
- Develop your .NET applications with easy GUI.
- Surf for your APIs with the help of the "HELP document" available with the software.
- Helps  in opening Word documents, Spreadsheets, PDFs, and your project files  on .NET applications including WPF, ASP.NET, WinForms, Web Services,  etc.
- You have all options here which you can find in MS-Office,  like find & replace, copy/paste, review your documents, working  with extensions, etc.
- Helps in the conversion of various file formats – Excel sheets – adding digital signatures, etc.
I  tried working with WPF projects with Data Binding, Animations, MVVM  model, developing a media player, isolated storage, etc., and I feel  Spire helps us with all features that Microsoft Visual Studio has in it.
Still,  Spire works in a large scale on conversion of file formats, merging the  data, exporting the data, accessing all data file formats, and multiple  printing orientations etc.
