I am currently in the process of taking my reference lists out of Omnifocus and moving them to Evernote. I am basically trying to accomplish the exact same thing you laid out in your original post. I found a quick work around.
Step 1: Open Evernote and create a search query for notes created today. This will display all your newly added notes from your OmniFocus actions
Step 2: Organize the OmniFocus actions you wish to migrate. For example, I have a lot of photography gear on my wishlist to buy. I created a project folder called “Photog to Buy” and moved all my projects containing the various lenses, lighting, and other things into this folder. Organize everything like this. I made each of these newly created project folders into its own note in Evernote.
Step 3: Click on the project folder. This will display all the projects. Go into the View menu and select “Show All Notes”. This will expand every action and display all your notes for ever project and action in the folder.
Step 4: With the project folder still selected, go to File and select “Export”. I chose to create a folder on my desktop called “Omni to Ever” and saved each project folder export as an HTML file.
Step 5: Open the newly created HTML file. This will open in your default browser. The resulting webpage will be a very organized layout of all your projects and actions from OmniFocus. If you had notes with the action/project, they will be displayed because you chose to display them all before exporting.
Step 6: Cmd A to select the entire webpage text. Right click, services, send to Evernote
Step 7: Go to Evernote and look in your note list. Remember, you have a search query already open to display all notes created today. Your new note should be at the top of the list if you have sorted by updated date. Mine show as “Untitled”. Look over the note. It should be in a very organized and nicely formatted list as a note in Evernote. Verify all the content and rename the note as you wish.
Step 8: Go back to OmniFocus, select the project folder, and change the status to Dropped. I decided to drop instead of delete in the event something goes wrong and I need to find it again.
Step 9: Reorganize your newly input lists in Evernote as you see fit.
This may not be optimal for everyone, but my goal was to create a list inside Evernote from several actions/projects inside OmniFocus. It literally took seconds to do for each one.
I hope this helps.
