# I hate the documentation of openpyxl and it took me a while to undertand their stuff. So I decided to write down this code.
# Has some wrapper functions that reads all rows from the excel sheet and also a function to read a particular row.
# Add some code to the functions if you wish to do something on fly like adding values to list and sorting them later.

First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:
