What software to use?

[pickledrick]

Hi
I have built a fully functioning global supply chain management system in google sheets.

I want to turn this into an online webapp where I can log in and up load the data and for the online system to mimic my google sheets system.

I will need to up load CSV file, those CSV files be cleaned and processed before being added to the database.

Then i need to perform calculations of the data and drop those results in other tables then view the tables in the online webapp.

I would also like to be able to input changes on the webapp and the database recalculate and show the updated results.

Can anyone advise the best group of languages (mysql, django or flask, php, etc etc) that I will need to know to create and finish the whole project?

Thanks in advance
