Convert Visio to HTML in Python

Microsoft Visio is a popular drawing software that is used to create diagrams, flowcharts and other illustrations. There are many use cases for Visio, from creating simple diagrams to complex engineering drawings. It uses the VSDX as a default file format for saving drawing files. In certain cases, we may need to convert Visio diagrams to HTML webpages. In this article, we will learn how to convert Visio to HTML in Python.

Python Visio to HTML Converter – Free Download

For converting Visio drawings to HTML webpages, we will be using the Aspose.Diagram for Python. We can create, edit, convert, and process MS Visio diagrams using the API. The API also makes it easier to manipulate the supported Visio file formats with easy-to-use properties and methods.

The Diagram class of the API is the root element of the Visio objects hierarchy. The save(string, SaveFileFormat) method of this class allows saving the diagram data to the file in a specified format. We have the SaveFileFormat enumeration that provides a saving diagram format selection. We can specify additional save options when rendering diagram pages to HTML using the HTMLSaveOptions class.

Please either download the package or install the API from PyPI using the following pip command in the console:

pip install aspose-diagram-python
