My first app to enable searching thru stories

I enrolled to C# Xamarin Tutorial with Mosh and just went through the titles.
I need to create a small application for my kid, to read stories. I have the stories as image files ( with rich, colorful images) and I have the content in Excel sheet to enable searching.
My idea is to:

  1. Upload the Excel content in SQLite DB.
  2. Enable search over the Excel.
  3. Highlight the story line in the image.

As a first step, I tried to create db3 file as we do local DB in C#.NET Windows application.
But I could not find the browser.
Can any one please just outline how I can do this. I don’t need details, just keywords.
