How to clear contents in some field in one time?

For some reason, I want to to clear all contents in 'Extra'. Are there any methods to achieve it?

For all items? And what exactly is your goal/purpose here?

I am using extension ' Zotero Scholar Citations', and I want to clear all contents in Extra before fetch data from Google Scholar.

That’s not really necessary—that plugin will add the number of citations to the top of Extra, before any existing contents.

I would recommend leaving Extra alone here—it’s used to store some important data sometimes (e.g., DOI names for book chapters). It’s possible to clear Extra for all items, and I could walk you through that if you want, but I’d advise against it in this case.
