What is a SPV file?
The .SPV file extension primarily belongs to the SPSS Output Document format. IBM created this file type for IBM SPSS Statistics. These files store the visual results of statistical data analysis, including charts, graphs, and tables.
However, software developers also use the .SPV extension for SPIR-V module files. The Khronos Group developed SPIR-V as an intermediate language for graphical shaders. These files contain compiled binary shader code used by graphics rendering interfaces like Vulkan.
How to open SPV files?
To open an SPSS Output Document, you generally need IBM SPSS Statistics or the free IBM SPSS Smartreader software. If your file is a SPIR-V shader binary, you must use command-line developer tools like `glslangValidator` or `spirv-dis` from the Vulkan SDK to read the contents.
Because .SPV has multiple possible meanings, we recommend using viewer.online/spv to identify the actual format of your file. viewer.online/spv analyzes .SPV files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
If your computer cannot open an .SPV file automatically, the operating system does not know which application to use. Do not rename the file extension to force it to open. Renaming does not change the internal data format. Instead, consider the source of the file. If you expect charts and statistics, it is an SPSS file. If you work with 3D graphics or game development, it is likely a shader.
Software and tools
- IBM SPSS Statistics: The primary commercial software for generating statistical data.
- IBM SPSS Smartreader: A free desktop tool to view and print SPSS outputs.
- Vulkan SDK: A toolkit that contains command-line utilities to inspect SPIR-V modules.
Summary
An .SPV file is usually an SPSS Output Document created by IBM, but it can also be a SPIR-V shader binary. Because .SPV files use the known ZIP format, viewer.online/spv can safely open and display them online, eliminating compatibility problems.
