Extract Number From Alphanumeric Text

[Rick Rothstein]

=LOOKUP(9.9E+307,1*LEFT(MID(A1,MIN(FIND({0,1,2,3,4 ,5,6,7,8,9},A1&"0123456789")),999),ROW($1:$999)))

this formula is not extracting all digits from alphanumeric value

My Input was a0-112455jkjk223
and result is coming 0

My formula was not meant as a replacement for this article's original formula. If you look at the section I quoted, you will see I was responding to this statement from the second message in this thread...

"A link that shows how to extract numbers that are placed together. Ex. ABC123DE
http://www.familycomputerclub.com/ex...eric-text.html"

If the digits for the number are all placed together, my formula returns them... if they are not all placed together, then my formula returns the first complete number it comes to. For example, if the text were ab123cd45efg678hijk, then my formula would return 123... the first complete number in the string. For the example you posted, the 0 is the first complete number (it is followed by a dash, a non-digit), so it returns that value.
