Import underscore in coding every after 2 digits

[Manos]

Dear All

I have a fixed coding with 8 digits. (ie: 40000000).
I need to change this and split it importing underscore every two digits in
order to look like (ie.: 40_00_00_00)
Any clever way to do it for 25000 rows?

Thanks in advance for your time....

--To retain these as numbers; select the range and from menu
Format>Cells>Custom and type as below

00"_"00"_"00"_"00

--OR as text; you can use a formula in ColB to convert
=LEFT(A1,2)&"_" & MID(A1,3,2)&"_"&MID(A1,5,2)&"_"&RIGHT(A1,2)

If you are trying to import this to elsewhere using code you can try the
format function as below

Format(range("A1"),"00_00_00_00")

=LEFT(A1,2) & "_" & MID(A1,2,2) & "_" & MID(A1,6,2) & "_" & RIGHT(A1,2)

=SUBSTITUTE(TEXT(A1,"00-00-00-00"),"-","_")

Or just:
=TEXT(A1,"00\_00\_00\_00")

The backslash is the escape character to indicate that the next character should
be treated as text--not a formatting character.
