ABAP to JSON

[naotoxxx]

Hello , i'm triying to convert an internal table that i fill by myselft and based on many structures and deep structures all created by me (SE11).

Reading this: https://wiki.scn.sap.com/wiki/display/Snippets/One+more+ABAP+to+JSON+Serializer+and+Deserializer

and use this:

LV_JSON = /UI2/CL_JSON=>SERIALIZE( DATA = it_main_tb COMPRESS = ABAP_TRUE pretty_name = /ui2/cl_json=>pretty_mode-camel_case ).

But is not formating with camelCase

lv_json=[{"businesspartnercategory":"2","businesspartnergrouping":"ZNAC","organizationbpname1":"RAZÓN SOCIAL","organizationbpname2":"A","organizationbpname3":"B","organizationbpname4":"C","toBusinesspartneraddress":{"cityname":"SANTIAGO","country":"CL","district"...

and i need it like this:

{
  "d": {
    "BusinessPartnerCategory": "2",
    "BusinessPartnerGrouping": "ZNAC",
    "OrganizationBPName1": "RAZON SOCIAL",
    "OrganizationBPName2": "A",
    "OrganizationBPName3": "B",
    "OrganizationBPName4": "C",
    "SearchTerm1": "",
    "to_BusinessPartnerAddress": {
      "results": [
        {
          "CityName": "SANTIAGO",
          "Country": "CL",
          "District": "02",
          "Language": "ES",
          "PostalCode": "8320000",
          "StreetName": "HOLANDA 99",
          "to_EmailAddress": {
            "results": [
              {
                "EmailAddress": "email@email.com"
              }
            ]
          }
        }
      ]
    },

So all "_" are deleted and is not formating with cameCase

What is wrong with my class call ? any ideas?

This might be obvious, but in the worst case, you can build the JSON text using Concatenate (or brackets); keeping any case rule you want. If you pick this path, the codebase here might help you a little: https://github.com/keremkoseoglu/ABAP-Library/blob/master/zcl_bc_json_toolkit.abap

Do you have field names in SE11 structures with underscores?
Like this: business_partner_category = businessPartnerCategory

Your code looks OK otherwise. So if you have field names correct (with underscores) then you probably need to update /UI2/CL_JSON. I think you have some old version with a bug. There are SAP NOTES with updates...
We are using this class a lot and it works great and is very helpful.
EDIT: note that for first letter in capital you need to have field name starting with underscore:
_test_field_name (fieldname) = TestFieldName (in JSON)

Yeap i noticed that i need a underscore before the letter that i want in capital , but thanks! 😄 the problem it's when my fields names are too long but i solve that with a replace all hehe

Thanks Tomas, this old answer pointed me in the right direction: the system I was working on indeed has such an old release that the standard /UI2/CL_JSON does not properly support camelCase and the Notes seem to be for much newer releases.

Fortunately, SAP provides a replacement, abap-to-json, which works beautifully!
