// Specify the template path
string template = "Bulleted List Template.docx";

// Set the output file path
string result = "Result Report.docx"

// Retrieve managers' data from a JSON source
JsonDataSource dataSource = new JsonDataSource("Report data.json");
DataSourceInfo data = new DataSourceInfo(dataSource, "managers")

// Generate the report with the filled data
DocumentAssembler assembler = new DocumentAssembler();
assembler.AssembleDocument(template, result, data);
