},
{
"name" : "testng2",
"age" : 1

The open-source VBA-JSON project helps with this.
Once you have installed it in your workbook's VBA project, you can do something like this:
Sub convertJson()
Dim c As Collection
Dim d As Dictionary 'Add reference to scripting runtime
Dim v As Dictionary
Dim json As String
Set c = New Collection
Set d = New Dictionary
d.Add "ExcelTest", c
For Each cell In Range("A2:A4") 'Adapt as you need
Set v = New Dictionary
v.Add "name", cell.Value
v.Add "age", cell.Offset(0, 1).Value
c.Add v
Next
json = JsonConverter.ConvertToJson(d)
Debug.Print json
End Sub
Outputs:
{"ExcelTest":[{"name":"test1","age":15},{"name":"test2","age":1},{"name":"test3","age":435}]}
