Need Help with JSON to KDB Table Conversion (Type Casting Issues)

Hi everyone! I’m relatively new to kdb+/q and currently stuck on JSON decoding.

I’m trying to convert arbitrary JSON data into KDB tables, but I’m running into consistent type casting problems. For example, some numeric fields in JSON are being interpreted as strings, and nested JSON structures don’t map cleanly to table columns. I’ve checked the documentation but haven’t found a straightforward solution for flexible type handling.
Has anyone encountered similar issues? Any tips, example code, or best practices for smooth JSON-to-table conversion would be really appreciated!
Thanks in advance for your help!

I wrote up some tips in this blog which could be helpful:
