You can see an example of the kind of data available from within the app here: https://formapps.co.uk/own-your-data/sample-data-set/
There is a really useful search facility so you can find the data you want.
You can also filter each column alphanumerically ascending or descending – just click or tap in the column headings.
The columns can be restricted if desired so that only critical data is shown. You can also download this as a spreadsheet which will contain all fields.
It is worth noting that contained within the full data-set there may be some additional fields with seemingly little relevance. If this is the case, these kinds of fields are used to control conditional fields and can be ignored if you wish.
