move products to uncategorized using CSV import

[lbfrazita]

Hopefully this is the right place to ask.

I'm using the CSV import/export file to make a mass update. Some of the products need to be removed from the category they were in temporarily.
What would I need to write in the CATEGORY_CODES field to remove a product from one category into no category?
I know that if I leave that field blank, it will keep items in the category they are already in.

Thanks in advance, and apologies if this is the wrong forum for this question.

there is an option to "update field when empty" so, you can create a line where its empty, then copy that line and add the correct category(ies).

test it on one cat first.
