I found a Python project that does enough for my needs. Jq looks super powerful though. Thanks. I managed to get yq working for PNG’s, but I had trouble with both jq and yq with safetensor files. I couldn’t figure out how to parse a string embedded in an inconsistent starting binary, and with massive files. I could get in and grab the first line with head. I tried some stuff with expansions, but that didn’t work and sent me looking for others that have solved the issue better than myself.
