There have been many updates over the past 2 years. Actual version is 1.50. Also there is an utility for creating a Clarion data structure corresponding to the json structure: > **[GitHub - mikeduglas/cJSON\_Mapper: An utility for creating a Clarion data structure...](https://github.com/mikeduglas/cJSON_Mapper)** > > An utility for creating a Clarion data structure corresponding to the json structure.

Hello everyone!! Here I am, always struggling with JSON, haha! I’m working with “cJSON mapper” and I have a question about the JSON I’m trying to read. “respuesta”, “comprobantesFiscales”, “comprobantes”, “otrosComprobantes” are arrays. Should they be QUEUED in the “MyObject” structure? Thanks ```PROGRAM INCLUDE('cjson.inc'), ONCE MAP INCLUDE('printf.inc'), ONCE END sJson STRING('' | & '{{' | & ' "estado": "ok",' | & ' "respuesta": [{{' | & ' "puntoventa": 1,' | & ' "emision": "CAE",' | & ' "comprobantesFiscales": [{{' | & ' "codigoTipoComprobante": 6,' | & ' "comprobantes": [{{' | & ' "monto": 5200,' | & ' "numeroNodo": 1,' | & ' "numeroTransaccion": 6,' | & ' "numeroComprobante": 133,' | & ' "horaEmision": "112404"' | & ' }]' | & ' }]' | & ' }, {{' | & ' "puntoventa": 1,' | & ' "emision": "OTROS",' | & ' "otrosComprobantes": [{{' | & ' "codigoTipoComprobante": 80,' | & ' "comprobantes": [{{' | & ' "numeroComprobante": 1,' | & ' "horaEmision": "112520"' | & ' }]' | & ' }]' | & ' }]' | & '}') MyObject GROUP estado STRING(2), NAME('estado') respuesta GROUP,DIM(2), NAME('respuesta') puntoventa LONG, NAME('puntoventa') emision STRING(8), NAME('emision') ! max string(5) comprobantesFiscales GROUP,DIM(2), NAME('comprobantesFiscales') ! max array[1] codigoTipoComprobante LONG, NAME('codigoTipoComprobante') comprobantes GROUP,DIM(2), NAME('comprobantes') ! max array[1] monto LONG, NAME('monto') numeroNodo LONG, NAME('numeroNodo') numeroTransaccion LONG, NAME('numeroTransaccion') numeroComprobante LONG, NAME('numeroComprobante') horaEmision STRING(8), NAME('horaEmision') ! max string(6) END END otrosComprobantes GROUP,DIM(2), NAME('otrosComprobantes') ! max array[1] codigoTipoComprobante LONG, NAME('codigoTipoComprobante') comprobantes GROUP,DIM(2), NAME('comprobantes') ! max array[1] END END END jParser cJSONFactory jRoot &cJSON, AUTO CODE !- JSON -> Clarion IF jParser.ToGroup(sJson, MyObject, FALSE, | '') !- Clarion -> JSON jRoot &= json::CreateObject(MyObject, TRUE, | '[{"name":"*","IgnoreEmptyObject":true,"IgnoreEmptyArray":true,"EmptyString":"ignore"},' & | '{"name":["comprobantesFiscales","codigoTipoComprobante","numeroNodo","numeroTransaccion","numeroComprobante","horaEmision","otrosComprobantes"], "JsonName":"*"}]') IF NOT jRoot &= NULL !- check result in DebugView printd(jRoot.ToString(TRUE)) jRoot.Delete() END END ``` ---

The mapper generates GROUP,DIM structures for json arrays. If you want the QUEUEs instead, do it yourself. I mean: replace groups with typed queue references ---
