Is the underscore symbol part of the entry for that column, or have
you just put those in to make your posting clearer? If they are
included, then this formula will give you what you want:

=TEXT(LEFT(A1,FIND("_",A1)-1),"000")&MID(A1,FIND("_",A1),255)

assuming your values are in cell A1. Put this in B1 and copy down the
column by double-clicking the fill handle (the small black square in
the bottom right corner of the cursor).

You can then hide column A, or you could fix the values in column B
and then delete column A.

Hope this helps.
