Вот "родная" библиотека VB JSON.
Можно использовать JSON, который уже есть в IE8 +. Таким образом, вы не зависите от сторонней библиотеки, которая устарела и не протестирована.

Sub myJSONtest()
Dim oJson As Object
Set oJson = oIE_JSON() ' See below gets IE.JSON object
' using json objects
Debug.Print oJson.parse("{ ""hello"": ""world"" }").hello ' world
Debug.Print oJson.stringify(oJson.parse("{ ""hello"": ""world"" }")) ' {"hello":"world"}
' getting items
Debug.Print oJson.parse("{ ""key1"": ""value1"" }").key1 ' value1
Debug.Print oJson.parse("{ ""key1"": ""value1"" }").itemGet("key1") ' value1
Debug.Print oJson.parse("[ 1234, 4567]").itemGet(1) ' 4567
' change properties
Dim o As Object
Set o = oJson.parse("{ ""key1"": ""value1"" }")
o.propSetStr "key1", "value\""2"
Debug.Print o.itemGet("key1") ' value\"2
Debug.Print oJson.stringify(o) ' {"key1":"value\\\"2"}
o.propSetNum "key1", 123

Вы можете подключиться к IE.JSON из VB.
