About JSON to ABAP Structure
REST APIs return JSON, but ABAP needs typed structures and internal tables before you can work with the data — writing those TYPE definitions by hand for a nested payload is tedious and easy to get wrong, especially with optional fields and arrays. Paste a sample JSON response and this tool infers the corresponding ABAP TYPES block, including nested structures and internal tables for arrays.
How to use this tool
- Paste a representative JSON response, ideally one with all optional fields populated.
- The tool infers a nested ABAP TYPE hierarchy, mapping arrays to internal tables.
- Review the suggested field names and data types (STRING, I, P) and adjust if the source system uses different precision.
- Copy the generated TYPES block into your class or /UI2/CL_JSON deserialization target.
- Use /UI2/CL_JSON=>DESERIALIZE with the generated structure to parse the real API response.
All processing happens locally in your browser. No data is sent to any server. Your SAP code and business data remain private at all times.
Frequently Asked Questions
What ABAP types does this tool generate?
The tool generates TYPES declarations, BEGIN OF / END OF structure blocks, and TABLE OF declarations. It maps JSON types to appropriate ABAP types: string → STRING or C, number → I, P, or F, boolean → ABAP_BOOL.
Can I use the generated code directly in my ABAP program?
Yes! The generated code is syntactically valid ABAP. You may need to adjust the length of character fields (type C) based on your actual data requirements.
