Input Output value from csv on frontend

Greetings everyone!

I hope that I am posting on the right forum. For the past 2 days I have been searching for a solution to a simple, yet hard problem – I am running woocommerce on website, selling physical goods to my customers, which are shipped by a local company. I keep an access database file with everyone’s order number and tracking number. Customers call me all the time to ask where their orders are.

What I am trying to achieve is:
I’d like to make a page, where a customer can type his order number in a search field and then get a tracking number, based on the already uploaded csv file. If there is no order with such number, a message should be returned that this order isn’t found.

A further improvement would be to have the shipping companies tracking page open on the same page in my website so that the customer can instantly see where the order is.

I have looked at almost all the tracking plugins and none of them has this option, at least not explained well enough for my not-knowing-php-mind.

Do you have any idea which plugin could do this or how the function I want is called so that I can hopefully find a solution?

Thank you very much for your time!
