Hi,

try to test with the B4X online parser.

Result (<text> is your string to parse)

B4X:
Dim parser As JSONParser
parser.Initialize(<text>)
Dim root As Map = parser.NextObject
Dim result As List = root.Get("result")
For Each colresult As List In result
   For Each colcolresult As String In colresult
   Next
Next

This json string is complex. If you need every value,you have to iterate manually.

B4X:
    Dim parser As JSONParser
    parser.Initialize(string2parse)
    Dim root As Map = parser.NextObject
    Dim result As List = root.Get("result")
   
    Dim sublist_1 As List=result.Get(0)
    Dim sublist_2 As List=result.Get(1)
    'sublist_1 sublist_2 has similar structure
   
'get values in sublist_1   
    Dim sublist_1_Guid As String = sublist_1.Get(0)
    Dim sublist_1_Timstamp As String = sublist_1.Get(1)
   
    Dim sublist_1_2_map As Map = sublist_1.Get(2)    'it's a map ;not list
    Dim sublist_1_Plext_map As Map=sublist_1_2_map.Get("plext")
   
    Dim sublist_1_text_string As String=sublist_1_Plext_map.Get("text")
    Dim sublist_1_plextType_string As String=sublist_1_Plext_map.Get("plextType")
    Dim sublist_1_categories_string As String=sublist_1_Plext_map.Get("categories")
    Dim sublist_1_team_string As String=sublist_1_Plext_map.Get("team")
    Dim sublist_1_markup_list As List=sublist_1_Plext_map.Get("markup")
    'values in sublist_1_markup_list
   
'get values in sublist_2 ...
