I need a simple yet visually beautiful web app that supports offline browsing. It needs to pick data from an Excel file (that will be updated daily, from Office 365) and display it after applying filters (as per image attached).
I need to be able to work offline, to see the latest data downloaded, and to download latest version available too (as per image attached).
As you can see it's very straightforward, needs to be very very nice visually.
