Read & Write YAML in AL (Business Central)

📌 Overview

Business Central AL now supports YAML via the existing JsonObject type:

Read YAML:

• JsonObject.ReadFromYaml(string)
• JsonObject.ReadFromYaml(InStream)

Write YAML:

• JsonObject.WriteToYaml(string)
• JsonObject.WriteToYaml(OutStream)

These methods let you convert YAML ↔ JSON seamlessly, read it into AL, manipulate it, and export it again

Use Cases

• Data-driven testing: Easily load YAML test cases, process them as JSON, and convert back if needed .
• CI/CD pipeline processing: Read pipeline YAML files directly in AL to drive business logic .
• Interoperability: Convert and exchange config data between JSON and YAML formats.
