Whistle Testing Tool

About the tool

Whistle is a data transformation language developed by Google used to map healthcare data from one schema to another.

I've built this tool to make it possible to quickly execute Whistle online and see the output. It should be useful for everyone who is working with Whistle, whether they're learning the language or writing complex mappings. Testing the Whistle logic against different sets of input data also helps to identify bugs and various edge cases.
