Function to Return a JSON Like Objects Using VBA Collections and Arrays

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with.

Will my employers contract hold up in court?

This contract seems incredibly binding, 2 years in length, and I’m looking to see if it would actually hold up in an Arizona court. contract employment non-compete arizona share | improve this question edited Aug 7 at 15:35 feetwet ♦ 13.8k 9 37 85 asked Aug 6 at 19:05 Alex S. 46 2 What does your company do and what services do they provide?
