Essential DocIO is a .NET library that can read, write, and modify Microsoft Word files. It features a full-fledged object model similar to the Microsoft Office Automation libraries. It can be used on systems that do not have Microsoft Word installed. Essential DocIO enables users to create richly formatted Microsoft Word reports in Windows Forms, ASP.NET, WPF, ASP.NET MVC, and Silverlight applications.
Essential DocIO can create and consume files based on a wide set of Word .doc file format variants.
Native file format for Word versions 97–2003Docx—Native file format for Doc Version 2007 and 2010.
You can even open a file in one format and save it back in another format.
Essential DocIO is a native .NET library written in C# which allows you to use it in a Windows desktop as well as Web apps, including a native version of Silverlight.
This also provides a much better user experience and performance compared to other solutions available in the market that are wrappers over COM components, libraries ported
from Java, Delphi, etc.
Essential DocIO has been optimized for usage 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 .doc files with a large amount of data. It is optimized for both low memory usage and speed. It works more than 100 times faster
than MS Word automation and consumes much less memory compared to that of MS Word.
The Silverlight version of the library is a native Silverlight client-side library that off-loads all the processing to the client machine, making it an infinitely scalable reporting
solution for your Web apps.
DocIO is very cost-effective since there are no per-server licensing fees, distribution fees, or royalties involved.
Essential DocIO has thousands of customers who require the generation of millions of Word reports every day in demanding production environments.
Essential DocIO lets you add Microsoft Word's reporting capabilities to your .NET applications within minutes. You can visually design your report with placeholders
called "merge fields" that are similar to those found in Microsoft Word. Essential DocIO can then be used to replace these placeholders during run time with real data and save the
final report to a local file, stream, or even stream to the client browser.
MS Word Forms let you create templates with control place holders to let users enter custom information to fill a form. Essential DocIO lets you fill such forms programatically
with data retrieved from your custom data sources.
Cloning And Merging
Multiple documents can be combined into a single document by utilizing the cloning and merging capabilities of Essential DocIO. This
feature is very useful when dealing with contents from several documents.
Using Essential DocIO, cloning can be done at the section level or paragraph level, wherein sections or paragraphs from various template documents are
combined to construct a new Word document.

pleasant background. You can apply a picture or text watermark using Essential DocIO.
Page, Column, and Section Breaks
Essential DocIO has support for creating a document with multiple column layouts. While using columns, often the text in the last column gets rendered with a width
that is inconsistent with the previous columns. But inserting a continuous Column Break will balance the column lengths, providing a professional and finished look
for the document created using Essential DocIO.
Page breaks refer to the end of a page of text. Essential DocIO offers support for including hard or forced page breaks in the Word document.
Word documents can be divided into sections and formatted individually using Essential DocIO.

Essential DocIO supports the conversion of MS Word documents to Rich Text Format [*.rtf]. You can now open and create MS Word documents and save them in RTF format,
enabling RTF conversion using Essential DocIO with same APIs. This enables transfer of formatted text to another application that does not automatically support Word format.
Essential DocIO allows you to do the reverse of the above as well, converting RTF documents to .doc.
.Doc-formatted files can also be converted to plain text format for consumption in low-end devices.
