Thank you everyone, all were relevant and helpful! The AddOnDepot's response is spot on. For my incredibly unsavvy code, I ended up using something like:
for (const [dataKey, peopleValues] of Object.entries(jsonParsed.data)) {
Logger.log(`${dataKey}`);
Logger.log(peopleValues.name);
Logger.log(peopleValues.title);
/* And was able to apply the same concept to access deeper nested values!
for( const [deeperNestedKeys, deeperData] of Object.entries(peopleValues))
{
Logger.log(deeperData.otherValue);
}
*/
}
My first tip off was actually from an old stackoverflow post that I didn't fully understand at first, so credit also to: https://stackoverflow.com/a/62735012/645379
