How can I remove a template?

I am new to the community and added a bunch of templates from the Community Solutions Add-on Gallery to see if/how I could use them in my budgeting. There are some that I added that I won’t use and would like to remove. For example, I thought the Linked Transfers template was going to do something a bit different, so I’d rather remove that now instead of having an extra column on my transactions tab. There are plenty of others that I added just to see what they were, but I’d like to remove them so they don’t slow down my workbook.


Please see the following link

Once you read the below, you can then remove the extra columns that were added by any templates. Perhaps make a backup first, in case you delete a column and it’s used in a sheet you still have.
