You need to write a small application where a client can upload an excel from the front end and it creates records in an IOS app.
Use the same login information that currently people use to login to our IOS App.
so its basically, Login into desktop website -->Upload a excel-->save to database-->Detect the data by IOS app.
here generally, i believe detecting the data by IOS is already there.
To do this task the required skills are:
Backend is NODE JS
DB is Mongo
PHP or HTML for designing a place to upload the excel on desktop website.
shall design keeping security in mind.
