    DOCX: Edit DOCX content
    In This Topic

    VintaSoft Office .NET Plug-in has a set of classes, which allow to edit content of existing DOCX document. Classes are designed for fast and easy development of report/invoice generator based on DOCX document template.

    If you want to generate DOCX report/invoice, you need to do the following steps:


    Report Generator Demo project contains several examples, which demonstrate how to generate reports, which are based on DOCX template.

    DocxDocumentEditor class

    DocxDocumentEditor class allows to:

    OpenXmlDocumentElement class

    OpenXmlDocumentElement represents a base class of all elements in a DOCX or XLSX document and allows to:
