Sorting Alphanumeric
Excel has a problem trying to sort alphanumeric cells in cells by the number portion only. The reason is simply because Excels Sort feature evaluates each cell value by reading left to right. However, we can over-come this in a few ways with the aid of Excel Macros .
Fixed Length Text
If the alphanumeric cells are all a fixed length we can simply use another column to extract out the numeric portion of the alphanumeric text and then sort by the new column. For example, say we can alphanumeric text in Column A like ABC196, FRH564 etc. We can simply add the formula below to Column B.
=--RIGHT(A1,3)
OR
=--Left(A1,3) for fixed length alphanumeric text like 196GFT
OR
=--MID(A1,5,4) for alphanumeric text like a-bg1290rqty where you know the number Start s at the 5th character and has 4 numbers
Then Fill Down as far as needed. Then we can select Column B, copy and Edit>Paste Special - Values. Next we sort Columns A & B by Column B and then delete Column B.
NOTE: the double negative (--) ensures the number returned is seen as a true number.

Any Length Alphanumeric Text
A problem comes about when the numeric portion and/or the text portion can be any length. In these cases a macro is best. The code below should be copied to any standard Module (Insert>Module). Then simply run the SortAlphaNumerics Procedure.
It should be noted that the ExtractNumber Function has 2 optional arguments (Take_decimal and Take_negative). These are both False if omitted. See the table below to see how alphanumeric text is treated.
Alphanumeric Text | Formula | Result |
a-bg-12909- | =ExtractNumber(A1,,TRUE) | -12909 |
a-bg-12909- | =ExtractNumber(A2) | 12909 |
a.a1.2... | =ExtractNumber(A3,TRUE) | 1.2 |
a.a1.2... | =ExtractNumber(A4) | 12 |
a.a-1.2.... | =ExtractNumber(A5,TRUE,TRUE) | -1.2 |
abg1290.11 | =ExtractNumber(A6,TRUE) | 1290.11 |
abg129013Agt | =ExtractNumber(A7) | 129013 |
abg129012 | =ExtractNumber(A8) | 129013 |
