IT guy here, Excel is a data analytics tool, not a database, not a word processor, not a sales system, not a photo album, not a notepad, not a paint program.
If at anytime you are treating Excel as a database, you are doing it wrong, and you deserve me mocking you when asking for help recovering it when it breaks, I won’t as I am not a dick, but if I did, you would deserve it.
If you want a database, build an SQL database, or have someone build it for you, not me.
