Can anyone help me successfully run this code?

Like this.
restore-the-great-suspender-urls --in-file=C:/Users/User/Desktop/the-great-suspender-restore-urls-0.4/tabs.json --out-file=C:/Users/User/Desktop/the-great-suspender-restore-urls-0.4/tabs_restored.json
You should learn to navigate on command line,here i demo in cmd i normal use cmder as it's much better.
Now i just put tabs.json on Desktop as a example,as you see when in that folder no path is needed.
If you don't use virtual environment,just forget about (suspender_env).

(suspender_env) G:\div_code\suspender_env>c:
C:\Users\Tom>cd ..
(suspender_env) C:\Users>cd ..
(suspender_env) C:\>cd Users
(suspender_env) C:\Users>cd Tom
(suspender_env) C:\Users\Tom>cd Desktop
# now in folder where tabs.json is
(suspender_env) C:\Users\Tom\Desktop>restore-the-great-suspender-urls --in-file=tabs.json --out-file=tabs_new.json
# No errors 

While I appreciate your effort, I'm afraid that wasn't really the question I asked. ^^;; I should probably rephrase it: Should I post (suspender_env) G:\div_code\suspender_env for each tabs JSON file individually, like this?

(suspender_env) G:\div_code\suspender_env
(File A)

(suspender_env) G:\div_code\suspender_env
(File B)

Or should I type (suspender_env) G:\div_code\suspender_env & post the code for both files one right after the other?

(suspender_env) G:\div_code\suspender_env
(File A)
(File B)
