Preparing your data in the right format
Before building a new app with AppSheet, the data source for your app needs to be in place. Throughout this book, we are using Google Sheets as the data source for our sample app and demonstration.

A tabular format is simply information presented in the form of a table with rows and columns, where the first row at the top always represents the name of columns and each row represents a subset of the data.
