The .NET Word Library is a feature-rich and high-performance library that allows you to add advanced Word document processing functionalities to any .NET application. It allows you to create, read, and edit Word documents programmatically without Microsoft Office or interop dependencies. It allows you to create complex reports by merging data from various data sources using its powerful mail merge engine. This library also provides functionalities for merging, splitting, organizing Word documents, and finding and replacing text with ease.
Optimized for a server environment where speed and low memory usage are critical, DocIO works much faster and consumes less memory when compared to Office automation libraries.
There are no distribution fees, per-server licensing fees, or royalties, making DocIO very cost-effective.
All the elements of a typical Word document like text, formatting, images, tables, sections, headers, and footers are accessible through a comprehensive set of APIs. It only takes a few lines of code to create or manipulate richly formatted Word documents.
Create, read, and edit popular text file formats like DOC, DOT, DOCM, DOTM, DOCX, DOTX, HTML, RTF, TXT, and XML (WordML). Convert Word documents to PDF, image (PNG, BMP, JPEG, EMF, TIFF), ODT, and EPUB files.
Design reports using Microsoft Word and uses DocIO to dynamically populate them with data. The final report then can be saved to a Word file or exported to other supported formats like PDF.

Populate the template Word document with data from common data sources like arrays, ADO.NET objects, IEnumerable collection, dynamic objects, and XML.
Format the merged text, numeric values, and date-times automatically with the help of field switches.
When the prefix “image:” is added to the merge field name, it places the image in the place of the merge field.
Customize a document during mail merge by formatting and editing the merged text, numeric and image data with mail merge events, and also the layout of the document by inserting breaks.
The library supports intuitive options like mapping merge fields with fields in a data source; retrieving merge field names; and removing merge fields that are not merged, empty paragraphs, and empty groups.
