PLEASE NOTE:

• At this very moment I'm rewriting the old library, the next coming v3.0 will be an incompatible version;
• I'm also working on a additional commerce library for the docx/xlsx support, closed-source library for MS-Office seems fair;
• The super old and buggy OfficeML support will be dropped, the OfficeML format is a legacy from 2003;
• More real world unit tests, more documents;
• Check dev branch to track the progress of the incoming v3 series.

MaltReport is an OpenDocument/OfficeOpenXML powered document template engine for .NET and Mono, it is inspired by the excellent Relatorio Project.

There is a briefly introduction in Chinese: MaltReport2 中文使用简介

MaltReport DO NOT REQUIRES MS-Office or LibreOffice to generate document. Instead MaltReport manipulates ODT/ODS/XLS/DOC file by itself, so it could be fast & reliable.

    { "image", image },
};

var context = new TemplateContext(data);

using (var stream = File.OpenRead("EmployeesTemplate.odt"))
{
    var odt = OdfDocument.LoadFrom(stream);
    var template = new OdtTemplate(odt);

    var result = template.Render(context);

    var desktopDir = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
    var outputFile = Path.Combine(desktopDir, "generated.odt");

    result.Save(outputFile);
