Generate Word Documents from Templates using C#

Wordize for .NET is a professional solution for automated reporting and programmatic Word document generation. The ReportBuilder class provides C# developers with comprehensive capabilities for creating Word reports using templates and LINQ syntax, helping accelerate business analytics processes and integrate dynamic content into automated document workflows.

Key Features:

Programmatic Word document generation - the ReportBuilder class provides the BuildReport() method to generate Word documents from templates
Flexible data source integration - supports JSON, XML, CSV, and programmatic objects (custom classes, object collections)
LINQ expressions for data filtering, sorting, and grouping during Word document generation
Customizable generation parameters - the ReportBuilderOptions class manages available data types, missing field handling, empty paragraph removal, and other Word document creation settings
Export to image format - the BuildReportToImages() method returns Word report pages as an image array
Fluent API support for report generation operations through ReportBuilderContext and method chaining, enhancing C# code readability

LINQ Reporting enables creation of professional Word documents with support for complex formatting, tables, and charts. Word files maintain editability, making them ideal for corporate documentation, contracts, and technical specifications.

Test the capabilities of programmatic Word document generation in the interactive online demo presented on this page. Upload a document template, load a data file (JSON, XML, or CSV), run the operation, and download the generated Word document for review.
