Generate a DOCX File from Markdown (MD) template via C# Code

//Setting up source document template
const String strDocumentTemplate = "Markdown Templates/ReadMe.md";
//Setting up destination Markdown reports
const String strDocumentReport = "Word Reports/ReadMe Out.docx";
//Setting up description variable
const string description = "GroupDocs.Assembly for .NET is a class library that enables you to generate documents in popular " +
    "office and email file formats based upon template documents and data obtained from various sources " +
    "including databases, XML, JSON, OData, objects of custom .NET types, external documents, and more.";

DocumentAssembler assembler = new DocumentAssembler();
//Assemble Document
assembler.AssembleDocument(
    CommonUtilities.GetSourceDocument(strDocumentTemplate),
    CommonUtilities.SetDestinationDocument(strDocumentReport),
    new DataSourceInfo("GroupDocs.Assembly for .NET", "product"),
    new DataSourceInfo(description, "description"));
}

Use Spreadsheet as a Data Source to Assemble a Document

string strDocumentTemplate = "Word Templates/Using Spreadsheet as Table of Data.docx";
string strDocumentReport = "Word Reports/Using Spreadsheet as Table of Data_Output.docx";
// Assemble a document using the external document table as a data source.
DocumentAssembler assembler = new DocumentAssembler();
assembler.AssembleDocument(CommonUtilities.GetSourceDocument(strDocumentTemplate),
    CommonUtilities.SetDestinationDocument(strDocumentReport),
    new DataSourceInfo(DataLayer.ExcelData(), "contracts"));
