Can you give us an example of how to run this? Also, what format should I export my macjournal in?

We're working on a fully supported Import function. Sorry I'm not able to assist on this one right now.

any chance there could be a way to import MacJournal (or other) CSV? Not so good at ruby and it seems like it wouldn't be that much work but it could take a while to figure out. :)

I had some serious issues getting this to work, so I wrote my own in python. See

The built in importer does not work. It returns: The operation could not be completed. No other information is available about the problem. Can anyone help?

What is the latest on the MacJournal importer? Will it import the tags and photos used in MacJournal entries?


Thanks for putting this up. The built-in import of MacJournal files dates the entries by creation date, rather than the MacJournal internal date. This gist addresses this, which is nice. However, with the newest version of Day One (1.10.2) the executable you refer to in line 18 does not work. I changed this line to:

Open3.popen3("/usr/local/bin/dayone", "-d=\"#{date}\"", "new") do |stdin, stdout, stderr|

And this appears to solve it.
