Why convert NUPKG to NUSPEC?

The .nuspec holds the package manifest including id, version, authors, dependencies, and license. You may need it to inspect metadata without installing the package, re-use it as a template for a new package, or push to a private feed that requires the manifest separately.

How to convert NUPKG to NUSPEC

7-Zip OPEN-SOURCE

Right-click the .nupkg, choose 7-Zip > Open archive, select the .nuspec at the archive root, and click Extract.

NuGet Package Explorer OPEN-SOURCE

Open the .nupkg via File > Open local package, select the .nuspec in the contents panel, then use File > Save metadata as to save it as a standalone file.

Rename to .zip FREE

Rename the .nupkg extension to .zip, open in Windows Explorer or use unzip on macOS/Linux, and copy out the .nuspec from the archive root.

Quality & what to watch

  • The .nuspec inside a built .nupkg reflects values resolved at build time (e.g., version from the .csproj), not necessarily a hand-written manifest.
  • The extracted .nuspec is complete and valid - it can be used directly with nuget pack to rebuild or fork the package.
  • The <files> element is usually absent in .nuspec files extracted from a dotnet pack build; file layout is resolved automatically at build time.

Frequently asked questions

Where in the `.nupkg` is the `.nuspec` located?
At the archive root, named <id>.<version>.nuspec.
Can I use the extracted `.nuspec` to re-pack the package?
Yes - it is a complete, valid manifest usable with nuget pack.
What is the difference between `.nuspec` and `.nupkg`?
The .nuspec is plain XML metadata only; the .nupkg is the full ZIP archive containing DLLs, the .nuspec, and all other package assets.
