I have two script projects for a spreadsheet. One was a temp one for development testing. I want to delete the temp one. When I click on script editor it shows both projects, and I can select one, but there is no option for deleting.
Also when I open the project itself there is no delete option. I have seen other SO threads (such as this), but it seems the interface is changed since then.
Script Editor File menu:
Make sure that you are the owner of the script.
I've tried to replicate your issue in other scripts which I don't own and it seems that I cannot see a
Delete Project...
option underFile
menu.But with my owned script, there is a
Delete Project...
option. See screenshot.Here's a reference post: How can I remove a project from a Google Spreadsheet?
UPDATE (based from OP's comment):
You must be the owner of the spreadsheet to show the
Delete Project...
option.
