-Microsoft Expression Language Emulator
+A browser based Emulator for [Microsoft Expression Language](https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#uriComponentToBinary) - used in Power Automate, Logic Apps and Azure Data Factory.
+
+The intent of the emulator is for new users to quickly build and try Expression Language statements without having to run their flow/app/pipeline first.
+
+The emulator requires nothing server side and can be hosted statically: for example at [nonodename.com](https://nonodename.com/el)
+
+Microsoft: I'd be very happy for you to pick this up and embed in the relevant authoring environments. Please get in touch if interested.
