If we create an app using a spreadsheet (‘start with data’ in the dev portal → Create App screen we have entities, relationships and pages automatically built for us with data also loaded.
I propose we also have that ability in an already existing app.
e.g. Say I have an app i’ve been working on for a few days and I realise I have a large spreadsheet, with data, and having those entities and data would be of great value. I would like to be able, with a few clicks, to be able to generate additional entities, relationships and pages automatically, with data. Maybe a menu item named ‘Add Content from xls’ or something to that extent.
Maybe an extension to that is to be able to quickly load data into existing entities from a spreadsheet with a single click (rather than having to import the Excel Importer from the App Store).
