' Imagine we have two separate JSON objects.
Dim jsonA As Chilkat.JsonObject
Set jsonA = Chilkat.NewJsonObject
Dim success As Boolean
success = jsonA.UpdateString("ciphertext","encryptedData")
success = jsonA.UpdateInt("status",200)
success = jsonA.UpdateString("error","errorMsg")

jsonA.EmitCompact = False
Debug.Print jsonA.Emit()

' jsonA contains:

' {
'   "ciphertext": "encryptedData",
'   "status": 200,
'   "error": "errorMsg"
' }

Dim jsonB As Chilkat.JsonObject
Set jsonB = Chilkat.NewJsonObject
success = jsonB.UpdateString("users[0].role","Surgeon")
success = jsonB.UpdateNewArray("users[0].sub_roles")
success = jsonB.UpdateBool("users[0].viewable_for_sharing",True)

Debug.Print jsonB.Emit()

' jsonB contains:

' {
'   "users": [
'     {
'       "role": "Surgeon",
'       "sub_roles": [],
'       "viewable_for_sharing": true,
'       "eula_create_date": 1649108922482

' Let's say we want to insert jsonB into jsonA to get this:

' {
'   "ciphertext": "encryptedData",
'   "status": 200,
'   "error": "errorMsg",
'   "users": [
'     {
'       "role": "Surgeon",
'       "sub_roles": [],
'       "viewable_for_sharing": true,
'       "eula_create_date": 1649108922482
'     },
'     {
'       "role": "Support",
'       "sub_roles": [
'         "Tech",
'         "Service"
'       ],
'       "viewable_for_sharing": true,
'       "eula_create_date": 1649108951523
'     }
'   ]
' }

' First add an empty array at the desired location (-1 means append to end).
success = jsonA.AddArrayAt(-1,"users")

' The destination is the empty "users" array, the source is the populated "users" array in jsonB.

Set jsonUsersDest = jsonA.ArrayOf("users")

Set jsonUsersSrc = jsonB.ArrayOf("users")
' Copy the array items from source to dest
success = jsonUsersDest.AppendArrayItems(jsonUsersSrc)

Debug.Print jsonA.Emit()

' The end result is this:

' {
'   "ciphertext": "encryptedData",
'   "status": 200,
'   "error": "errorMsg",
'   "users": [
'     {
'       "role": "Surgeon",

'       "sub_roles": [
'         "Tech",
