How would I parse HTML data from a website?

Hey everyone, I recently started to learn about https and how to use it with Roblox lua. Although still pretty confused, I think I understand the basics. Looking at it in the Roblox Dev Hub, it gives an example suggesting that the website returns JSON data. Now most websites I have encountered don't do this, and instead, return HTML data.

This brings me to my main question: How would I "Parse" HTML data, or more accurately, sort HTML data into a table without a third party item?

Thanks in advance!

HTML data is meant for viewing and not reading data from.. when you go to Roblox.com it returns an HTML form for your browser to display.. HTML does not have descriptive fields(properties) that you can read to get useful data.. i mean you can have an external server with an HTML parsing library, but this is not good practice.. so i recommend that you just stick to web servers that return JSON data b/c roblox has methods that you can use to parse it into a lua object(JSONEncode and JSONDecode)..
