Users spreadsheet
If you want to assign groups to the users in the users spreadsheet, you need to install our extension for “Groups”. Go to the toolbar > Extensions > Important Extensions > Download the “Groups” Extension and install it.
This extension will add a “Groups” column where you can edit.
Posts spreadsheet
If you want to edit posts using the posts spreadsheet, and assign “group” permissions to the posts. Go to the toolbar > Extensions > Important Extensions > Download the Multiple Fields Key Extension.
Once the extension is installed, go to Settings > Advanced Settings > Misc > Multiple Keys Fields > Add “post: groups-read” as a value.
You need to replace the word “post” on the text with whatever post type you’re putting the restriction on, for example, for WooCommerce products you have to add product: groups-read.
