From a Text File

Bonsai Outliner for Windows > How Do I ... ? > Import Data > From a Text File

The desktop application supports importing from a text file.  Each line in the file is used to create an item in the outline.  Tabs at the start of each line are used for the outline levels. 

The import command is located on the File menu. The command creates a new outline with the imported information.  After performing the import, the save command will create a new Bonsai outline file.
