iGTD to Omnifocus (OS X international settings)
 

If you are trying to import from iGTD to Omnifocus using the importer at my [URL="http://web.mac.com/robinfrancistrew/Site/iGTD2Omnifocus.html"]download page[/URL] there should be no problem if your international settings specify "." as the decimal point separator.

In some countries, however, decimal numbers are traditionally separated by a comma, and if this is specified in System Preferences as your local default, the importer fails with an error of the kind:

"Il est impossible de rendre \"218538583.482917\" en type real."
or
"\"218538583.482917\" can not be converted to real"

The solution is to temporarily set your region (through System Preferences\International\Formats\Region) to an Anglo-Saxon location like USA or UK, run the importer, and then switch back to your own location.
