我怎样才能建立一个系统来检查我在文本框中写的文本是否存在于工作表中？

Question

I have a very simple question because I am very new and trying to learn. I want to create a text box on my own website and write a system that checks whether what is written in that box is in google sheets and says to the user whether it exists or not.

I dont know where should i start.

It's just an example but and you can change it in the way you want.

let mainData = "this is our main string data...";
let inputString = "this in my entered val";
        
        
let result = mainData.includes(inputString);
