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 allows merging, splitting, organizing Word documents, and finding and replacing text with ease.
