Extract only date into new column

I have a report extracted from shop software into Excel 2010. Unfortunately in column A I have job number (in text format) in row 1 and due date (in date format) in row 2 and so on...

COLUMN A
ROW1 Job No
ROW2 Due Date
ROW3 121033
ROW4 01/24/13
ROW5 121018
ROW6 01/31/13
ROW7 121019
ROW8 01/31/13

I would like to have them separated, or at least COLUMN B showing me only date (DUE DATE), have no need for JOB number (Job No)

I tried this IF function:

=IF(ISERROR(DATEVALUE),TEXT(A17,"mm/dd/yyyy")," ")
but it turns the job number (in text format) into a date

any ideas, my brain is either overthinking this, or I'm really in lack of coffee to see the simple solution.

Formula:

=IF(ISERROR(DATEVALUE),TEXT(A17,"mm/dd/yyyy")*1,"")

I get: #VALUE!

Formula:

=INDIRECT("A"&(ROW())*2)

I get: 0
but I need the row with the date to be shown in COLUMN B as date

Formula:

=IFERROR(INDEX($A$1:$A$52,ROWS($A$1:A1) *2),"")

I get: 0 as well on all rows

It works:

121033 1/24/2013
01/24/13 1/31/2013
121018 1/31/2013
01/31/13 1/31/2013
121019 2/11/2013
01/31/13 4/1/2013
121020 4/5/2013
01/31/13 4/9/2013
121205-2 4/19/2013
02/11/13 4/22/2013
130204 4/23/2013
04/01/13 5/1/2013
130328 5/3/2013
04/05/13 5/6/2013


however (sorry) I need the row where the job no is(ex 121033) to be left blank, as I have amount on column C that relates to the due date.
121033
01/24/13 $1
121018
01/31/13 $2
121019
01/31/13 $3
121020
01/31/13 $4
121205-2



Ultimately what I'm trying to achieve is a graph of Sales figure by due date and reason why I need to separate column A due date from Job No (Number). I hope this makes sense.
