you see this part? this is json. note all the quotes and the separating ":"
B4X: 
{
"status": true,
"data": [
{
"RefNo": "0253",
"CartTotal": "1000",
"CustomerName": "Kb Villar",
"MobileNo": "31949",
"Urgency": "Express",
....

you see this part? this is NOT json. note there are no quotes and the "=" instead of a ":" as separator.

B4X: 
[{RefNo=0253, CartTotal=1000, CustomerName=Kb Villar, MobileNo=31949, Urgency=Express, DeliveryDateTime=2020-06-25 16:00:00,

all those "="'s are wrong. not json. how did you get from json to not json?? how did you get the first part? the correct part?

-----------------------------------------------------------------
next case: the code
snippet of your code:

B4X: 
        jp.Initialize(job.GetString)
        map1 = jp.NextObject
        jg.Initialize(map1)
        Log(jg.ToPrettyString(2))
      
        If map1.Get("status") <> False Then
          
            If map1.Get("data") <> Null Then
                Private jp2 As JSONParser
                Private m As Map
              
                Log(map1.Get("data"))
              
                jp2.Initialize(map1.Get("data"))
                m = jp2.NextObject

should be:

B4X: 
Dim json As JSONParser
json.Initialize(job.getstring)
Dim walker As Map = json.NextObject
Log("status: " & walker.Get("status"))
  
Dim list As List = walker.Get("data")
Log(list.Size & " items")
for each record as map in list
   ' do something with each record retrieved from list
   ' eg record.get("RefNo")
   '      record.get("CartTotal")
   '      etc
next

you already had a jsonparser. i don't know what you thought you were doing declaring a second one on the same object.
testing for status false is fair enough, but testing for data = null is not going to happen, and i don't think it's what you were looking for. data could be [] but not null. if you have to test for something, you want to test for size of data (0 = no records).

Thank you so much for your response.

How was I able to get from JSON to no JSON.

B4X: 
 If job.Success Then
        Private jp As JSONParser
        Private map1 As Map
        Private jg As JSONGenerator
        
        jp.Initialize(job.GetString)
        
        map1 = jp.NextObject
        
        jg.Initialize(map1)
        
        Log(jg.ToPrettyString(2))  'the JSON part
        
        If map1.Get("status") <> False Then
            
            If map1.Get("data") <> Null Then
                Private jp2 As JSONParser
                Private m As Map
                
                Log(map1.Get("data")) 'no JSON

Since I was trying to see why it's giving me an error. Also, I think you have answered this already, when you mentioned regarding the second parser.
Also, the I did the 2nd parser on the Sub before the one with the error, and it worked. So I just did the same. I will heed your advise and work from there.
