trouble converting numbers into dates

[troyandmarsha]

i converted a DAT file via the automatic text import
wizard. i have numbers that represent the dates but
excel doesn't see the numbers as date numbers. every time
i try to format the numbers into dates a completely
different formatted date appears. any suggestions?
thanks.

Hi!

Can you give examples of what's being imported and what you think it
should be?

yes, thanks. the numbers coming over into the cell are
10204 which is january 2, 2004. but when i format the
cell to DATE and choose m/dd/yy as the format, then click
OK, it then displays as 12/8/1927. any idea what i'm
missing?

Troy,

In Excel, dates are stored as the number of days since 0-Jan-1900
(1 = 1-Jan-1900, 2 = 2-Jan-1900, etc), so the value 10204 is
treated as 10,204 days since 0-Jan-1900, or 8-Dec-1927.

You should probably skip the text import wizard and write your
own import routine and convert the values appropriately. Some
basic code for importing data can be found at
www.cpearson.com/excel/imptext.htm .

Hi Troy!

Excel uses a datetime serial number where the serial number is the
number of days since 31-Dec-1899.

You number 10204 is interpreted as 10204 days from 31-Dec-1899 which,
if I recall correctly, was 8-Dec-1927.

It seems that you'll have a mixture of numbers

10204 as 2-Jan-2004
120504 as 5-Dec-2004

You can parse these into dates using:

With the date in A1:
=DATE(RIGHT(A1,2)+2000,IF(LEN(A1)=5,LEFT(A1,1),LEFT(A1,2)),IF(LEN(A1)=
5,MID(A1,2,2),MID(A1,3,2)))
If A1 is 10204 this returns 2-Jan-2004
If A1 is 120505 this returns 5-dec-2004

I'm hoping you don't have dates before 1-Jan-2000 as that complicates
things a tad.

Having converted and checked that all is OK you can:
Select the cells containing formulas
Copy
Edit > Paste Special > Values
OK

The offending original data can now be deleted.

Hi Troy!

Thanks for thanks and confirmations are always useful for Google
Searchers. I usually test all replies but there are always mistakes
and often much better ways of doing things.

I'd rather not be King for the day! I'm a Republican and my wife would
only be after some crown jewels <vbg>

Have you tried using customise rather than date format?
