Sample App for a Table Lookup App?

I have a spreadsheet that I want to convert into a simple, 1 page app.

The UX would be simply two dropdowns, one choosing the “row” value (or record name) and one selecting the “column” value (or field name), with a live output of the resulting cell value.

  1. Is there a sample Ionic app that has this kind of structure?

  2. It’s a smaller amount of data, so instead of connecting to a database, I’m wondering about options to store the data in the app itself?
