SharePoint Online: How to import .wsp package into Visual Studio 2019?

Question

Hi,

I have a requirement to modify the master template deployed to solutions in SharePoint Online. I downloaded the .wsp package but don't know to how to open it via Visual Studio and make modifications. Please let me know how I can modify , deploy and package the new .wsp to Solutions?

Also, once uploaded, is there an additional process to activate it?

Any help is greatly appreciated. Thank you in advance.

Regards
SLS

Hi @sravya shivapuram ,
As far as I know, you can only open the wsp file as a cab and modify the files from there. The downside is that all the code will be compiled into assemblies and there will be no way to extract the code from them.

You could create a new Visual Studio web part project and add the assemblies from the wsp file and see if there are any open facing classes or members that can be accessed and go from there.
