Extract Bookmarks to New Document
A bookmark is used to assign a name to a position or an area in a document so it can be referred to from elsewhere, e.g. in cross-references or macro code. You can manually add bookmarks via the Ribbon tab Insert > Bookmark. Word also automatically adds bookmarks in some situations, e.g. when generating a table of contents. If a document contains many bookmarks, you may wish to get an overview of all the bookmarks and any contents enclosed in the bookmarks in one place.
Here you will find link to a free Word add-in that lets you extract / export all the bookmark data to a new document.
