What is an OD file?
An .OD file can be one of several different data formats. Often, it relates to the OpenDocument format used by Apache OpenOffice and LibreOffice. However, an .OD file can also be a Mascopt Graph Request File developed by INRIA/UNSA. Additionally, some .OD files store marine automation object data for the Kongsberg Maritime K-Chief system, or CANopen device configuration data.
How to open OD files?
Because the .OD extension has multiple possible meanings, it is difficult to know the correct program immediately. If it is an OpenDocument file, you can open it with Apache OpenOffice. If it is a Mascopt Graph Request File, you need specialized tools from INRIA/UNSA. We recommend viewer.online/od to identify the actual format of your file.
Software and tools
viewer.online/od analyzes .OD files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. You can also inspect the file structure manually using command-line tools like `file` on Linux or a hex editor.
Best practices and troubleshooting
Do not change the .OD extension manually. This does not convert the file format. Always identify the internal structure first. If your operating system asks you to select a program, use an inspection tool to find the real file type before you install new software.
Summary
Because many .OD files use the known ZIP format as an underlying container, viewer.online/od can safely open and display them online, eliminating compatibility problems.
