During my time at Accredible, I created a great little component for importing spreadsheets into the system. It was heavily based on the MailChimp UI, whereby after uploading your spreadsheet you would then map the columns of your sheet to the data-points of the system. If you've ever used MailChimp you'll be familiar with the UI. For Accredible, this interface complimented their Master/Detail view where you could CRUD individual objects.
With FlowVRP I have decided that this interface will be the only way you can get data into the system. Certainly for the MVP. The decision means that I can do without a tonne of UI elements for managing data. Tables of data with filters, searches, pagination and actions such as create, update and delete - all replaced with a single component.
The UI works really well, I'm feeling pretty smug!
