Extract text from Lotus Organizer files (OR3)
To convert OR3 Organizer files to another format, you need Lotus Organizer or other Database software.
To convert other file formats to the "Personal Organizer Database" file type, you need software like Lotus Organizer or a similar tool.
The .OR3 file extension is a proprietary data file used by Lotus Organizer version 97 (also known as Organizer 3). It stores personal information management (PIM) data, including calendars, contacts, to-do lists, and notes. This software was highly popular in the 1990s as a digital replacement for physical day planners.
This format is extremely obsolete and relies on a closed, proprietary encoding system developed by IBM. Users face a massive challenge today because modern applications like Microsoft Outlook or Google Calendar cannot read .OR3 files directly. If you do not have the original legacy software installed on an older Windows machine, you are effectively locked out of your own data. The file cannot be easily viewed in web browsers or standard text editors.
The ideal target formats for this data are standard files like CSV for contact lists or ICS for calendar events. However, because this is a complex, undocumented relational database format, standard online converters almost always fail to parse it correctly.
This is why this file format is difficult to open or convert: often only the original software can properly read or export the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported. Even if full database conversion is impossible, our analysis tools may extract raw text strings, allowing you to recover critical notes and contact names.
Convert.Guru analyzes your OR3 file, detects the exact format, and lets you read the text inside.
Users also converted OR4, OR6 and OR2 files.
If you want to convert OR3 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Lotus Organizer or similar software from the "Personal Information Management Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to OR3, try Lotus Organizer or another comparable tool in the "Personal Information Management Data" category.
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 OR3 converter.
