Extract text from OmniOutliner templates (OO3TEMPLATE)
To convert OO3TEMPLATE templates to another format, you need OmniOutliner or other Text software.
To convert other file formats to the "Outliner Template File" file type, you need software like OmniOutliner or a similar tool.
The .oo3template file is an OmniOutliner Template created by The Omni Group. It stores structural defaults, styles, and boilerplate text for creating consistent outlines in OmniOutliner. Professionals use these templates to quickly generate standardized documents, task lists, budgets, and project plans.
This format presents significant real-world challenges because it is strictly proprietary and locked to the macOS and iOS ecosystems. You must purchase a paid OmniOutliner license to natively open, edit, or export these files. They are completely unsupported by web browsers, Windows, and Linux operating systems. Furthermore, they are often saved as macOS 'packages' (folders acting as files), which can corrupt or appear as a messy directory of XML and image files when transferred to a non-Apple device via email or USB.
To share the structure, converting a .oo3template to an open format like OPML (Outline Processor Markup Language) is highly recommended for cross-platform compatibility. You can also export the data to DOCX for standard word processing, CSV for spreadsheet applications, or PDF for read-only viewing. Be aware that proprietary OmniOutliner styling, embedded media, and complex row hierarchies might flatten or lose formatting during conversion to basic text formats.
Because it is a closed Apple-centric format, standard online converters often fail to process .oo3template files accurately. Often, only the original OmniOutliner software can properly read or export the structured data. Even if the file is locked, our analysis tools can often inspect the internal package, extract the underlying XML content, and recover your text data.
Convert.Guru analyzes your OO3TEMPLATE file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our OO3TEMPLATE converter.
