Scan a barcode into spreadsheet App

Does anyone know of a barcode scanner app for iOS that allows one to:

1) Open a simple spreadsheet that contains empty column/fields next to pre-filled column/fields.

2) The user selects an empty field, scans a barcode (using the camera or a Bluetooth scanner) which inserts the barcode number into that field.

I have found a very simple app (for iOS & Android) named "Scan to spreadsheet" however, it is "too" simple, allowing only to user defined columns.

I have found plenty of Android apps which allow unlimited user defined columns, but nothing similar (yet) for use on an iPhone or iPad.
