Hi everyone,
I need to clean up a phone number column, below is an example of the data. I need to remove spaces, dashes, leading and trailing spaces, letters, etc, which I did with the data cleansing tool just fine, but I also need to remove generic phone numbers such as 666666666 or 000000000, but not sure how to do that I tried to use regex but I am a newbie and could not figure out how to do it. Any Idea?
Thanks.
Data example:
| Client Id | Mobile Phone |
| 1 | 646-285-6758 |
| 2 | 666666666 |
| 3 | 508-787-1000 |
| 4 | 212-207-2175 |
| 5 | 9-011-972-545- |
| 6 | 914-844-6711, |
| 7 | 505- 692- 9967 |
| 8 | 000000000 |
| 9 | 917000000 |
| 10 | 860 248 1457 |
