Convert Spellcasting Ability information into a full object

"special_abilities": [{
    "name": "Spellcasting",
    "desc": "The acolyte is a 1st-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 12, +4 to hit with spell attacks). The acolyte has following cleric spells prepared:\n\n• Cantrips (at will): light, sacred flame, thaumaturgy\n• 1st level (3 slots): bless, cure wounds, sanctuary",
    "attack_bonus": 0
}]

would read something like

"special_abilities": [
    {
        "name": "Spellcasting",
        "desc": {
            "spellcasting_level":1,
            "spellcasting_ability":"wisdom",
            "spellcasting_dc":12,
            "spellcasting_attack_modifier":4,
            "spellcasting_school":"cleric",
            "spells":{
                "cantrips": [ "light", "sacred flame", "thaumaturgy" ],
                "1st":[ "bless", "cure wounds", "sanctuary" ]
            },
            "spell_slots":{
                "1st":3
            }
        }
    }
]

I’d love input/thoughts on structure, key names, etc above.

Indeed, but my point about spells being just spells and the fact that they’re cantrips, level 1 or 9 is relevant to the spell, not to the monster. So I would keep the following structure with the spells slots adapted. Here’s my take with the archmage:

"spellcasting": {
	... ,
	"slots": {
		"1": 4,
		"2": 3,
		"3": 3,
		"4": 3,
		"5": 3,
		"6": 1,
		"7": 1,
		"8": 1,
		"9": 1,
	},
	"spells": [
		{
			"name": "Fire Bolt",
			"url": "..."
		},
		{
			"name": "Light",
			"url": "..."
		},
		{
			"name": "Mage Hand",
			"url": "..."
		},
		{
			"name": "Prestidigitation",
			"url": "..."
		},
		{
			"name": "Shocking Grasp",
			"url": "..."
		},
		{
			"name": "Detect Magic",
			"url": "..."
		},
		{
			"name": "Identify",
			"url": "..."
		},
		{
			"name": "Mage Armor",
			"url": "..."
		},
		{
			"name": "Magic Missile",
			"url": "..."
		},
		{
			"name": "Detect Thoughts",
			"url": "..."
		},
		{
			"name": "Mirror Image",
			"url": "..."
		},
		{
			"name": "Misty Step",
			"url": "..."
		},
		{
			"name": "Counterspell",
			"url": "..."
		},
		{
			"name": "Fly",
			"url": "..."
		},
		{
			"name": "Lightning Bolt",
			"url": "..."
		},
		{
			"name": "Banishment",
			"url": "..."
		},
		{
			"name": "Fire Shield",

		{

		{

		{
			"name": "Scrying",
			"url": "..."
		},
		{
			"name": "Wall of Force",
			"url": "..."
		},
		{
			"name": "Globe of Invulnerability",
			"url": "..."

		{
			"name": "Teleport",
			"url": "..."

		{
			"name": "Mind Blank",

	]
}

Lol. I just realize that @Alex-frazer said that to both of us a bit ago.
