Hi AutoIters!
Here is my new UDF about GUIs: it's an enhanced mixture of Advanced InputBox (deprecated) and KODA Parser (deprecated), with additional functions.
What you can do with it:
Parse KODA files and directly create GUIs (_GUIUtils_CreateFromKODA)
Parse a simple JSON form definition to simply create advanced InputBoxes with any amount/type of input controls (_GUIUtils_CreateFromJSON)
Created GUIs are returned as Scripting.Dictionary objects, and you have help
