Building a JSON Wrapper in AL for Business Central
In this live coding session, Stefan builds a JSON wrapper codebase unit in AL for Business Central — abstracting the verbose, multi-step JSON token handling that AL requires into clean, fluent get/set calls. The stream covers implementing typed get functions (text, integer, decimal, boolean, date, and more), iterating over JSON arrays with for-each loops, and constructing nested JSON objects and arrays using a more readable syntax. The finished wrapper lives on GitHub and is ready to drop into your own BC projects.
