Can I import data from another system (like Toggl)?
You can import projects, clients, tasks, and tags from a file. If you’re on a paid plan (or trial), you can also import timesheets.
If you’re computer savvy and know your way around the command line, you can use one of the two unofficial Toggl to Clockify importers. The project is developed and maintained by 3rd a party developer, so use it at your own discretion.
