Question [Q] how extract an *.ab file (Helium Backup)

Hi,

I've backup a few apps from my Nexus 5 (Unrooted),
I've copied the .ab file to my PC and I wondered how can I extract it to edit some file and then repack it again.

I've already tried to extract it using DroidExplorer but I'm getting an un-openable tar file.

Can someone please point me how to can I do it right? and how can I repack it again,

Thanks in advance!

Thanks man, I tried but I get an error while trying to extract the tar file,
also I saw this warning at the end of the guide:

Warning about Helium (Carbon): helium backups are just android adb backups that are not compressed with Java Deflater. It means they were created with the option static final boolean COMPRESS_FULL_BACKUPS = false.
A normal adb restore should work.

see log from first step:
