Remove empty lines in file with VSCode but only at the start and end of file-CodePudding

Here is my text :

     <---- empty line to delete
     <---- empty line to delete
Lorem ipsum
Lorem ipsum
     <---- empty line to keep
Lorem ipsum
     <---- empty line to delete

Here's what I would like to have using VSCode regex, or any extension you might know about.

Lorem ipsum
Lorem ipsum

Lorem ipsum

Any idea ? Thanks!

EDIT: I might need to precise that I want to achieve this on more than 12000 files. So can't imagine doing this manually.. And I haven't found any extensions yet, neither answers about this subject.

The second empty line you can remove with \n $(?![\r\n])

For the first couple of empty lines the following fits your example (?<!([a-z]|\n))\n but probably there are cases where this fails.
