[Request] Simple program to split hex into seperate files

Hello, I'm currently in the process of interpreting and editing ACNL collision files for its outdoor acres (grd_jmp.bin). So far I've been doing things by hand mapping them out, and as you can see below its been quite tedious.



I have no programming knowledge and would love if someone could make me a basic tool that would save these separate hex maps into 261 separate files.
It would be optimal to have them spit out in groups of 2 bytes as seen...
