How to get Large SpreadSheet Data

Hey Niotron User,
I’m facing some problems in my project.

  1. I’m using Spreadsheet Component in my app for data storage. Which has lot of different columns and these columns contains lot of data. I was using GetColumn Method but it took 20 seconds to load data from database.So I tried it getSheet method and it was quicker. but i was having problem showing data in the list. How Can retrieve data using this block. I will attach my blocks below.
  2. How does Referral Component(in experimental section) work.
  3. Can i pay for Niotron Premium using UPI
