Most of the justifications for using collections of command-line Unix tools are no longer valid today. Instead you should be using a proper programming language.

Note that people who still do use complex solutions built from cat, head, cut, etc, and who know what they're doing, will typically either write a shell script (which won't be structured particularly differently from the equivalent Python or whatever) or will rely heavily on awk (itself a full-featured programming language, no easier to learn than any other scripting language), or both.

One-liners which pipe text between four or five different commands are the equivalent of hand-soldered boards or bitwise arithmetic. Interesting to learn about for historical reasons but of no practical utility.

The use of things like xargs and jq in this solution, difficult to invoke Unix utilities for doing things that are trivial in any reasonable language, makes this even more clear.
