Fair point Howard. If the spreadsheet has nothing personal in it then the application password is not a biggie. I did say large personal file and for clarity I meant with any content that could be used or triangulated for identity theft.
Date of birth
Bank name
Addresses
I only mean this to illustrate not be rude. If you had a spreadsheet listing a group of 20 people going on a Morgan touring holiday and had their names, addresses, passport details, DoB, car reg and then tour information it is a golden nugget to the right person even well after the event.
The other issue with these tools is that they can also become "parallel IT" to a company system as they are faster, easier and more complete in many cases. I dealt with this a lot. Few companies held pace with the speed of mobile device engineering.
Salespeople would take extracts of customer databases and save them to dropbox to share with partners. These could be retained, forwarded etc. The company could then by called up for GDPR breaches. The password would have assisted in the compliance.
For reference I use it as well. I have some IoT home CCTV which exports the clips up to dropbox using API's just in case the camera gets nicked during the break-in!
