Extract text from Visual Studio extensions (VSIX)
To convert VSIX extensions to another format, you need Microsoft Visual Studio or other Plugin software.
To convert other file formats to the "Visual Studio Extension" file type, you need software like Microsoft Visual Studio or a similar tool.
A .vsix file is an installation package used to add features, themes, and integrations to Microsoft Visual Studio and Visual Studio Code. Under the hood, it is formatted as a standard ZIP archive that complies with the Open Packaging Conventions (OPC) standard.
Users often need to convert or inspect these files to verify the security of an extension before installation, or to manually extract its underlying assets. The primary disadvantage of the .vsix format is its rigid tie to the Microsoft developer ecosystem. It is proprietary in function, meaning you cannot easily run or edit its contents without an integrated development environment (IDE). Standard text editors and operating systems will not natively open the package without manual intervention.
The most practical conversion target is ZIP. By extracting the archive, you gain access to internal JSON, XML, and DLL files. Note that any compiled binary code (such as DLLs) will remain unreadable without specialized decompilation software, but metadata and UI assets will be fully accessible.
This file format is difficult for generic online tools to handle because they expect flat media streams, not multi-file archives. Just drag and drop your file to identify the format, view it, and convert it when possible using convert.guru. If our analysis detects the underlying ZIP structure, viewing or extraction of embedded content may still be possible.
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 Microsoft Visual Studio or similar software from the "IDE Extension Package Archive" 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 Microsoft Visual Studio or another comparable tool in the "IDE Extension Package Archive" 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.
