My Excel spreadsheet from time to time is inserted with a lot of rubbish.
Even when I delete the colums sometimes their formatting that stay this rubbish means the size of the spreadsheet grows intensively.

In the past i used to use an addin that helps me clean all unnecessary data from the spreadsheet.
I cannot find this add-in anymore and I’m not sure what keywords to search on Google in order to find it.


I was hoping that somebody from the form may have a better idea what addin I am referring to.

Thank you for your help
