Convert GRAPHML to YGF

Understanding the GraphML and YGF file formats

GraphML is an XML-based file format designed for describing graph structures, including nodes, edges, and their associated data. It is widely used for exchanging graph data between different applications and supports complex graph features such as hierarchies and metadata.

YGF (YFiles Graph Format) is a simpler, text-based format developed by yWorks for use with their yEd graph editor and related tools. YGF files are optimized for fast loading and saving of graph structures, but they do not support as many advanced features as GraphML.

Why convert GraphML to YGF?

Converting from GraphML to YGF is often necessary when you want to use graph data in yEd or other yWorks tools that support YGF for faster performance or compatibility reasons. YGF files are particularly useful for large graphs where quick loading is essential.

How to convert GraphML to YGF

The most reliable way to convert a GraphML file to YGF is by using the yEd Graph Editor, a free and powerful tool from yWorks. Follow these steps:

1. Download and install yEd Graph Editor from the yWorks website.
2. Open yEd and go to File → Open to load your GraphML file.
3. Once the graph is loaded, go to File → Export and select YGF as the export format.
4. Choose your destination folder and save the file.

This process ensures that your graph structure is preserved as much as possible during the conversion.

Recommended software for conversion

• yEd Graph Editor – The best and most straightforward tool for converting GraphML to YGF. It is free, cross-platform, and supports both formats natively.

Tips for successful conversion

• Check your graph for advanced features in GraphML (like custom data or hierarchies) that may not be fully supported in YGF.
• After conversion, review the YGF file in yEd to ensure all nodes and edges are correctly represented.
