Extract text from VSIX files
To convert your VSIX file to another format, you need Visual Studio or other Developer software.
To convert other file formats to the "Extension Archive" file type, you need software like Visual Studio or a similar tool.
The .VSIX file extension is a container format used by Microsoft to distribute extensions for Visual Studio and Visual Studio Code. While incredibly useful for adding functionality to your IDE, the format presents significant challenges for transparency and auditing. Because the operating system treats .VSIX files as executable installers, users often cannot easily inspect the underlying source code, assets, or manifest files without specialized tools or risky installation. This proprietary wrapping hides the contents, making it difficult to verify security or extract specific resources like icons and libraries manually.
To overcome this "black box" limitation, the most practical solution is converting the .VSIX file to a standard ZIP archive. Since .VSIX follows the Open Packaging Conventions (OPC), converting it to ZIP allows you to unzip the package using standard tools like 7-Zip or Windows Explorer. This grants immediate access to the internal extension.vsixmanifest (XML), package.json, and source files for auditing or editing.
Convert.Guru analyzes your VSIX file, detects the exact format, and lets you read the text inside.
Users also converted VSIXPACKAGE, ZIP, AAE, MDP, LIB and DTD files.
If you want to convert VSIX file to DLL, SO, DYLIB, BUNDLE, PLUGIN, XPI, CRX, SAFARIEXTZ, APPEX, KEXT, SYS or DRV, you can use Visual Studio or similar software from the "IDE Extension Packaging" category. In the File menu, look for Save As… or Export….
To convert LV2, DYLIB, VST, AAX, DRV, TDE, LADSPA, BUNDLE, AU, DLL, RTAS or SO files to VSIX, try Visual Studio or another comparable tool in the "IDE Extension Packaging" 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 VSIX converter.
