The inventory writer actually got me off my butt to write an Excel macro worksheet that will accept 5E stats and output a chatsetattr macro that will add the stats and the correct modifiers to a NPC. I may add some more error catching and documentation and release it in the wild. Here are the elements that it adds to the the character: size, type and alignment ac ac type HD, HP, and HP calculation (based on size, chosen hit dice, and Con modifier) speed (based on numbers entered for speed, burrow, climb, flight [hover yes/no], and swim) ability scores (with mods based on score entered) CR (with proficiency bonus based on CR chosen) languages entered senses (based on number entered for darkvision, tremorsense, blindsight, and truesight, and the perception skill) save bonuses skills (based on whether or not the creature is proficient or expert) resistances/immunities/condition immunities/vulnerabilities (based on yes/no) It doesn't have a great interface, but it does format things such that it saves me a lot of time entering a creature and it looks like a creature should.
