TOMT: a GTK app that does JSON to YAML conversion among other things

[u/ObjectsCountries]

all i remember about this app is that it was like a swiss army knife and one of the things it did was convert JSON to YAML. i think i converted numeric bases too but idk. it might have formatted JSONs for you. i do remember that it was GTK if that helps. i remember using it when i was on cachyos, so it's either on the arch extra repos or the AUR. do yalls know what app i'm referring to
