I have a project that automates price book information. All of the code controlling the data validation and handling sits in the code.gs file. The sheet works quite well and now we have 54 sheets (one for each supplier). All of these sheets are a copy of the original.
Where the challenge comes in is if we make a code change, we currently have to make the changes and test in a "template" copy of the current version. Once tested and approved, we then have to make 54 copies using the new template.
Is there a way to share a common code.gs file where we could manage all iterations of the project "books"
