Extract text from UV2 files
To convert your UV2 file to another format, you need Keil uVision or other Developer software.
To convert other file formats to the "IDE Project File" file type, you need software like Keil uVision or a similar tool.
The .UV2 file extension is a legacy project file format generated by Keil uVision2 and uVision3, Integrated Development Environments (IDEs) historically used for 8051, 251, and C16x/ST10 microcontroller development. These files act as the central blueprint for embedded projects, storing critical build configurations, compiler flags, debugger settings, and the list of source files (C, ASM) included in the build.
Because .UV2 files are obsolete - superseded by .UVPROJ in uVision4 and UVPROJX in uVision5 - working with them today presents significant friction. They are proprietary and tightly coupled to the directory structure of the original machine they were created on. Opening a decades-old .UV2 file in a modern version of Keil MDK often triggers migration wizards that can fail if source paths are broken. Furthermore, because the format is not standard XML (unlike newer versions), extracting build logic for modern CI/CD pipelines or converting to Makefiles or CMake usually requires manual parsing.
For active development, the best course of action is to import the file into the latest Keil uVision to upgrade it to UVPROJX. For archiving or inspection without installing legacy software, converting or renaming the file to TXT can allow developers to scrape compiler settings and file lists using a standard text editor.
Convert.Guru analyzes your UV2 file, detects the exact format, and lets you read the text inside.
Users also converted SIM, SGR, VIV and UV1 files.
If you want to convert UV2 file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Keil uVision or similar software from the "Embedded IDE Project Configuration" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to UV2, try Keil uVision or another comparable tool in the "Embedded IDE Project Configuration" 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 UV2 converter.
