An extension to VSCode which allows you to generate JSON files with sample data for your OData service described in metadata XML file (either locally or online). The files can be then used by UI5's OData Mock server. faker.js methods can be used to provide sample data, also data can be related if needed (which is handy for testing navigation links). The backbone of this extension is my other project - OMG OData Mock Generator
Please check the GitHub page for all configuration options and sample usage.
