I have an administrative user who is does data entry, not real technical. Would they be able to once as week append the database table from an csv or excel sheet from a form with a few clicks?
Hi @mlefler,
You could certainly build an app with a file input to take cxv/excel sheets and append that data to your database 
You could build out the logic to parse the file they input and append it. If your user has a paid seat in your Retool org, they could log on to the app and submit the new sheet
You could also create a public Retool Form (similar example here), but you wouldn't have the benefit of authenticating your user
Keep us posted if you run into any blockers or questions
