## Introduction
CX is the data exchange format, implemented as JSON, for Cytoscape Cyberinfrastructure (CI) services and applications. With this app, you can import and export networks in CX JSON format from/to a file.
As of June 2016, this format is used for data exchange between Cytoscape and [NDEx](http://www.ndexbio.org/) database, and eventually, this will be used by all other Cytoscape CI services.
### Use Cases
CX is a new standard based on JSON. Your application can use a standard JSON reader to import files generated with this app, and your application should interpret the JSON according to the [CX Format Specification](https://docs.google.com/document/d/1kAUzVj6X86YCWHnTyZtybh1lt4zO-M6anCMJBD_PyG0/edit?usp=sharing). If you are planning to create Cytoscape CI services, you can use this app to generate test data from existing Cytoscape session files.
### CX Format Specification
