Bulk tagging items

@shhh I don't see any built in function in 1Password that would scan the free text notes and add words from it as tags to the item. This is incompatible: free text in the notes (could contain anything, not only your manually added tagging keywords) and the machine readable real tags.

I'm a very lazy person and automate everything possible, and if there is something to automate on my computer I will write some batch/powershell/perl/php script to do this. However even this is not a thing I would try to script. It could probably be automated by export the account to a *.1pux file, then extract the json-representation of your database, then write a script to scan it, then scan the notes, then add the notes as tags to the json, the rewrite the database export, then recreate the *.1pux, then reimport it. Possible, but feasibility depends on the amount of items to process. What would take longer? Editing everything manually, or write and test the script?

You can try this by using the desktop app of 1Password:

• create one item for each of your tags, so the tag list/tag hierarchy actually appears in the sidebar of 1Password.
• search for a tag within the notes, so the search result is a list of items.
• select all items from the search result and drag the selected items with the mouse to the tag in the sidebar to assign them this tag
• repeat with the remaining tags

This way you can bulk assign the tags half manually, half automated. Only one search and one drag operation per tag, not one search and edit per item.
Small caveat: the now useless text in the notes field remains.

You find remaining/untagged items by searching for =untagged (or the corresponding translation of "untagged" in your language, in case you use a different language than English for 1Password)
