You can import your Wunderlist account data to Microsoft To Do using our importer. To import your lists and tasks:
Head to Settings and select Import.
Sign in to your Wunderlist account.
Once you've signed in, we'll show you the number of lists and tasks that will be imported from your Wunderlist account to Microsoft To Do. Assignments and members of shared lists will not be imported.
Select Import begin moving your lists and tasks over from Wunderlist to Microsoft To Do.
When the import is finished, you can view a summary of everything that was imported by selecting Details when prompted in the app.
Alternatively, you can also view the summary at any time by heading to Settings and selecting the option to Show last import summary.
In Microsoft To Do, your subtasks will be imported as steps and your folders as list groups. Comments aren't currently supported in To Do, so we'll import them as a note.
Please know that your data in Microsoft To Do will not remain in sync with your Wunderlist account. If you continue using Wunderlist after importing, you'll need to use the importer again to migrate your latest changes to To Do.
