The AD-DA.ca EzJSON plugin brings JSON processing capabilities to Q-SYS, enabling seamless encoding and decoding of JSON data structures.

JSON (JavaScript Object Notation), recognized as a standard for data interchange in modern applications, allows structured data exchange with web services, APIs, and third-party systems in a lightweight and human-readable format.

The plugin supports dual-mode operation. In Encode mode, key/value controls are transformed into a JSON string output. In Decode mode, an input JSON string is parsed and mapped back to key/value controls with automatic type detection.

Key features

Dual operation mode - switch between Encode and Decode
Dynamic data pairs - configure from 1 to 64 key/value rows per instance
Multi-type support - string, number, boolean, null, object, array
Pretty JSON output - optional formatted JSON with indentation
Decode key selection - select parsed keys using per-row Select controls
Per-row hold behavior - retain decoded values with Hold toggles
Status diagnostics - detailed status and fault messaging
Debug print levels - console verbosity control via Debug Print property

Use cases

Build JSON payloads for external REST APIs from Q-SYS controls
Parse incoming JSON-like text payloads into deterministic control rows
Bridge Q-SYS logic with cloud services and control orchestrators
Create layered/nested JSON using daisy-chained EzJSON instances
