Extract text from NUPKG files
To convert your NUPKG file to another format, you need Microsoft Visual Studio or other Developer software.
To convert other file formats to the ".NET Library Package" file type, you need software like Microsoft Visual Studio or a similar tool.
A .NUPKG file is a NuGet Package, the standard mechanism for sharing code in the NET ecosystem. Internally, it is simply a ZIP archive containing compiled code (b), metadata manifests (b), and related assets.
While essential for developers using Visual Studio or the NuGet CLI, the format poses challenges for direct inspection. Because the operating system treats it as a specialized package rather than a generic archive, users often cannot double-click to view the contents without specific developer tools installed. Furthermore, inspecting a package to verify versioning or check for malicious code inside the DLL files is difficult without extracting it first.
To access the contents without the dotnet CLI, the most practical solution is to convert or rename the file to ZIP. This allows immediate access to the internal folder structure using standard tools like 7-Zip or Windows Explorer. For auditing or archiving, extracting the NUSPEC file (XML metadata) is crucial.
Convert.Guru analyzes your NUPKG file, detects the exact format, and lets you read the text inside.
Users also converted NUSPEC, ZIP, KST, DLL, HTML, TXT, JPG, ONEPKG, JSX, TORRENT, MP3, EXE and PKPASS files.
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 NUPKG converter.
