What is an OSC file?
An .OSC file is typically an OpenStreetMap Change File. The OpenStreetMap project uses these files to store updates, additions, and deletions made to global map data. These files use an .XML structure to log the history of map edits before they are permanently applied to the main database.
However, the .OSC extension is also used by several other software systems. It can be a vehicle script file for the game OMSI 2, an EBSD orientation scan data file for EDAX OIM Analysis software, a 3D kitchen design project for Oskab, or an oscillography trace file for Beckwith Electric devices and the CODESYS Development System.
How to open OSC files?
Because an .OSC file has multiple possible meanings, you must know its origin to open it correctly. You can open an OpenStreetMap Change File with GIS mapping tools like Osmosis, editing tools like iD, or any standard text editor. You must open OMSI script files in text editors, while you need specific proprietary software for EDAX, Beckwith, and CODESYS data files.
If you are unsure what kind of data your file holds, viewer.online/osc can analyze .OSC files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
File Conversion
If you need to use your map data in other applications, you can convert it to standard formats. We recommend using convert.guru to convert .OSC files to sensible target formats like .XML, .CSV, or .GEOJSON.
Summary
An .OSC file can contain mapping data, game scripts, industrial sensor data, or 3D designs. Because the file format varies widely based on the creator software, viewer.online/osc is useful for identifying, inspecting, and understanding .OSC files without installing software or dealing with compatibility problems.
