Import CSV file from the web page

Dears,

As we know that we have the ability to create APPa dn it’s backend “web app” and share the DB between them.

My question is:

  • How to give to upload CSV file from his backend screen

Note:

  • the user not can’t access the collection or the app DB in adalo, he will work under external URL.

thanks

is it so hard to answer!!
