API which is a feature-rich, powerful and easy to use conversion API for Python platform. You can download its latest version directly from


How to Create VDX via Python

It is easy for the developers to create, load, modify and convert VDX (Portable Document Format) within running different reporting applications for data processing in just a few lines of code.

  1. Include the namespace in your class file
  2. Create Diagram class instance.
  3. Access the first page of the diagram.
  4. Add text in the page.
  5. Use save method to save the diagram as VDX file.

System Requirements

Aspose.Diagram for Python is platform-independent API and can be used on any platform (Windows, Linux and MacOS), just make sure that system have Java 1.8 or higher, Python 3.5 or higher.

  • Install Java and add it to PATH environment variable, for example: PATH=C:\Program Files\Java\jdk1.8.0_131;.

Create Html Python Conversion Source Code

import  jpype     
import  asposediagram     
from asposediagram.api import *
// Create Diagram class instance.
diagram = new Diagram();

// Access the first page of the diagram.
page = diagram.getPages().get(0);

// Add Text shape.
shape = page.addText(1, 1, 1, 1, "Test text", "Calibri", "#a5a5a5", 0.25);

// Save the Diagram as .vdx file.
An Visio Programming Library capable of building cross-platform applications with the ability to generate, modify, convert, render and print VDX files. .NET Visio API not only convert between spreadsheet formats, it can also render Visio files as images, VDX, VDX and more, thus making it a perfect choice to exchange documents in industry-standard formats.

VDX What is VDX File Format

Any drawing or chart created in Microsoft Visio, but saved in XML format have .VDX extension. A Visio drawing XML file is created in Visio software, which is developed by Microsoft. Microsoft Visio has the capability to generate visual documents that can be used in presentations and documents. The Visio drawing XML file contains the visual objects and metadata details of the visual elements. Text can also be added to these visual elements Vision drawing XML file. These Visio drawing XML files are integrated with XML-based formatting standards and image data encoding specifications that allow its content to be rendered and stored by the Microsoft Visio software in the VDX file format.
