Frequently Asked Questions
What is a GML file?
A GML file stores a graph — its nodes, edges and attributes — in the GML format (also: Graph Modelling Language). See the feature table above for what it supports.
How do I open a GML file?
Open it in a graph tool that supports GML, or convert it to a format your tool reads. With GraphInOut you can convert GML to GraphML, DOT, Connected JSON and more, right in your browser.
How do I convert a GML file to another format?
Use the Convert from GML link above: upload or paste your GML file (input preset to GML), choose a target format and download the result — free, no install.
