Syncfusion Essential DocIO

Syncfusion Essential DocIO features a full-fledged object model (similar to the Microsoft Office Automation libraries) and an extensive range of functionality, including support for formatting and customizing content, mail merge, inserting tables, bookmarks, protecting a document, working with streams, inserting headers and footers, and much more. You can also convert Word docs to & from the HTML, RTF formats, and convert Word files to the Text, EPUB, and PDF formats. The library can create and consume files based on a wide set of Word .doc file format variants – it’s compatible with the native file format for Word Versions 97-2003, and the .docx format for Versions 2007 and 2010. Essential DocIO has been optimized for use on servers where speed and memory usage are critical. It can easily handle multiple requests for report generation in scenarios such as Web sites serving reports to hundreds of simultaneous users. Essential DocIO is also highly optimized to generate Word files with large amounts of data. It works more than 100x faster than Microsoft Word automation and consumes much less memory. This 100% C# library allows you to read and create richly formatted, standards-compliant Word reports in Windows Forms, ASP.NET, WPF, ASP.NET MVC, and Silverlight applications. Essential DocIO features simple, hassle-free licensing, with no per-server fees, distribution fees, or royalties. It’s available stand-alone or as part of Syncfusion’s Essential Studio Enterprise Edition and Essential Studio Reporting Edition packages. Complete, easy-to-work with source code is available with the Source version of the product. Visual Studio 2008 & 2010 are supported, and the product is compatible with the Visual Studio 2012 RC. Every Syncfusion license is backed by a 1-year subscription for access to frequent new releases (one per quarter) and unlimited technical support during the period of coverage, ensuring you can get the answer you need, when you need it.
