Could you please explain a bit for "what can be my best way to conclude all the data to one file at the end "?
PowerApps currently doesn't have any direct option available to export data into a readable file like Excel, or CSV format. If this is what you would like to achieve, then please consider submit this as an idea.
Further, if you just want to export all the data involved as a local file, then the possible workaround should be:
1. Collect all the data needed into a collection, with Collect () function,
Another workaorund is to save the collection to a pre-defined Excel file, which need to be added as data source, once the Collection is ready, we could take use of ForAll() function to update the data in the Excel table, using patch together.
Post back if you have any further questions.
