Aspose.Words Mail Merge for .NET

The Aspose.Words Mail Merge for .NET plugin offers robust capabilities for dynamic document generation. With predefined templates and merge fields, developers can efficiently integrate and personalize data into document structures. This streamlines automated document workflows, such as generating personalized documents with just a few lines of code. The plugin supports various development environments and enables seamless integration within .NET applications, enhancing productivity for C# and VB.NET Mail Merge implementations.

Mail Merge needs Processor plugins to save the results. For Word formats such as DOCX or DOC, make sure the Word Processor plugin is active. You can save in the same Word format without activating additional plugins. To save to other formats, activate the corresponding Processor plugin, for example PDF Processor for PDF, Web File Processor for HTML/MHTML, eBook Processor for EPUB/MOBI/AZW3, or Image File Processor for image rendering.
