ABAP to JSON serializer and deserializer
About this project
This is an Open-source version of the standard /UI2/CL_JSON class, and its public documentation was previously available on the SCN wiki as "One more ABAP to JSON Serializer and Deserializer" in 2013.
The official delivery of /UI2/CL_JSON will continue. The Open Source version (Z_UI2_JSON) is your way to contribute and get updates sooner using ABAP Git infrastructure.
Why
There are a lot of other implementations of the ABAP to JSON Serializer and Deserializer in SDN. Still, I found all implementations unsuitable for my needs for different reasons. From SAP_BASIS 7.40, there is also a simple transformation available for converting ABAP to JSON and JSON to ABAP. It is the best choice if you need maximal performance and do not care about serialization format, but it fits badly for properly handling ABAP types and name pretty-printing.
So, I have written my ABAP JSON serializer and ABAP JSON deserializer, which have some key differences from other implementations.
Here, you can find an Open-Source version of the standard /UI2/CL_JSON class in the form of a Z* class that you can use as a local or global one.
An original and current source version can be found in class /UI2/CL_JSON delivered with UI2 Add-on (can be applied to SAP_BASIS 740 – 76X). So, you can use this ABAP JSON parser in your standard code, mostly on any system.
The minimum required SAP_BASIS version for the class is SAP_BASIS 7.31 (ABAP language dependency, e.g., usage of "escape" function).
