How do I save extracted phone numbers from text file to phonebook?

I want to save extracted phone numbers in text format to mobile phonebook/vcard at once.

Any help please?

If the extracted numbers are on your phone. Import them to your SD card. It'll come up as VCF.info which will be the phone numbers in a compiled list.

The numbers are in text format like this
‪4 703 393 4043‬, ‪06 098 9780‬, ‪ 706 395 4009‬, ‪4 706 514 5835‬, ‪4 706 860 2904‬, ‪4 706 972 3638‬, ‪4 708 033 9869‬, ‪4 708 264 9515‬, ‪
I want to export all at once
to my android phonebook so that I can use it for whatsapp broadcast.
Help me please
