JSON

The JSON helpers wrap the bundled ajson library so you can serialize and parse with a single call.

json_stringify

Serialize any ABAP value (structure, table, ref, …) to a JSON string.

DATA(lv_json) = zabaputil_cl_util=>json_stringify( ls_flight ).
" => '{"CARRID":"LH","CONNID":"0400","FLDATE":"2025-01-15"}'

ABAP booleans (abap_bool) are mapped to JSON true/false. Empty values follow the ajson defaults — see the filter helpers below to drop them.

json_parse

Deserialize a JSON string into a typed ABAP value passed by CHANGING.

DATA ls_flight TYPE sflight.
zabaputil_cl_util=>json_parse(
    val  = '{"CARRID":"LH","CONNID":"0400"}'
    data = ls_flight ).

Field names in the JSON are matched case-insensitively against the structure components.

JSON Filters

The class zabaputil_cl_util_json_fltr implements zabaputil_if_ajson_filter and exposes a factory:

create_no_empty_values

Returns a filter that drops false, 0 and empty strings, and removes empty objects/arrays once their children are filtered out.

DATA(lo_filter) = zabaputil_cl_util_json_fltr=>create_no_empty_values( ).

You can pass the filter into ajson directly when you need the leaner output for HTTP responses or front-end communication.

boolean_abap_2_json

Convert any ABAP boolean-ish value to a JSON literal. Useful when you build JSON manually:

DATA(lv) = zabaputil_cl_util=>boolean_abap_2_json( abap_true ). " => 'true'
