I am searching for a way to do something very similar- grab extents of bookmarks created somewhere (initially thought in AGOnline, but I can use MXD too)
I too would like to be able to export/save the extents of the bookmarks so I can use them in iframes. I can go to 'share' at each bookmark and get the code I need, but was hoping that I did not have to do that dozens of times. The whole idea is for me to provide extents and iframes to our web guy to create an overview map and then several zoomed in maps (based on my bookmarks) to several different pages. Having everything in one location (extent links, URLs) and using one web map would really help as right now, the web person creates a separate Google map for each map type.
This does not allow you to export the bookmarks but if you have bookmarks already created in a webmap it will let you to copy them to other webmaps or multiple webmaps at one time. It will also let you reorder the bookmarks if you need to do this as well. You can get the tool here https://marketplace.arcgis.com/listing.html?id=c34019b0623041608df4d06970a7a96a Admin Tools for ArcGIS Online.
Let me know if this helps.
