How do I strip out all non-numeric characters?

I have 10,000 phone numbers, of which people entered in different formats, such as
212.123.1234
212 123 1234
212-123-1234
(212)123-1234

How do I strip out ALL the data/characters that are NOT numbers so the result is

2121231234

I want all my phone numbers to be consistent. I can individually FIND and REPLACE the .()- and spaces with "" nothing but sometimes there remain hidden characters after the 10 numbers. I know this from doing a =LEN(A1) and it reports 11, even though I see only 10 numbers. If I highlight the field and hit delete at the end of the 10 numbers, it deletes SOMETHING which is invisible and takes the length to 10 numbers as it should be.

So, how do I strip out ALL the data/characters that are NOT numbers so the result is only the 10 numbers?

### Excel Facts

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.

Another way if you have Morefunc:

Excel Workbook
AB
1212.123.12342121231234
2212 123 12342121231234
3212-123-12342121231234
4(212)123-12342121231234
example
Excel 2003
#VALUE!
Entered with Ctrl+Shift+Enter. If entered correctly, Excel will surround with curly braces {}. Note: Do not try and enter these manually yourself

regexp seems to be one of the best option to remove all type non-numeric characters.

This works perfectly except for when the cell is blank/empty, it returns a value of zero/0.

THanks to all for the superfast replies. My skill level is beginner.

You could test for that in an IF statement:

=IF(A1="","",SUMPRODUCT(MID(0&A1,LARGE(INDEX(ISNUMBER(--MID(A1,ROW(\$1:\$25),1))*
ROW(\$1:\$25),0
),ROW(\$1:\$25)
)+1,1
)*10^ROW(\$1:\$25)/10
))
