Checklist: how do I clear all the check-boxes?

What I’m trying to do

I travel a lot. So I have developed a checklist for packing. It’s one note per item, each with a #checklist tag. They’re displayed in a dataview that allows me to check the boolean “completed” box.

What I want is to start a new checklist by clearing all the “completed” fields for all the items on my list.

I don’t want to generate a whole new checklist from a template, which I don’t think would work with a collection of notes.

In short, what I want is a way to say: see all these notes in this filtered base/dataview? Set the boolean “completed” property to false for all of them.

The docs and the forum items seem to mostly suggest a template to create a new single checklist document, with a list of checkboxes. My checklist is a collection of notes, so this doesn’t apply.

In a base column, you can copy an unchecked box (a false), multi-select checkbox cells, and paste.

Obsidian Bases uncheck all

Another option is a plugin that writes to properties in multiple notes at once. Linter does it. Multi Properties probably does too (based on what I’ve heard; haven’t tried it).

Thanks, I have Linter installed, and will give it a try.
