Count unique values and create list based on these values

I have the below data. Firstly, I don't want to use excels autofilters. My
data changes monthly. I want 2 worksheets, one that contains data pasted in
by users, which will vary in length and the other worksheet functioning as a
report sheet interrogating the data on spreadsheet 1. On worksheet 1 column 1
will have multiple entires but with many duplicates. I want the report sheet
to count the number of unique values and count them, and now the tricky bit,
generate a list displaying this data. I have in other reports set my column
ranges as an example to a2:a30000.

1 2
120209 CONELECT
120209 CONMISGS
120209 CONMISGS
120215 CONBATT
120215 CONCAIRO

Perhaps a bit more detail on what you mean by "a list displaying this
data" would enable someone to readily give meaningful help.

Thanks for that RagDyer. On the spreadsheet where the data was I inserted a
column and put the following code ina cell. =IF(COUNTIF($A$2:A2,A2)=1,A2,"").
this worked fine. As originally specified I wanted the code to be on a
separate worksheet, but obviously looking at the data worksheet. i used this
code =IF(COUNTIF(sheet1!$A$2:A2,A2)=1,A2,""). all it returns is zeros's.
tried a few things. Any ideas?

You say it returned zeroes?!?!

It should have returned *blank* cells ... N0?

But, then again, I don't know what you have in Column A of the Sheet where
you've entered this formula.
Your formula is looking in Sheet1 for the data list, *BUT* looking in the
sheet containing the formula for *both* the matching criteria *and* the cell
to be returned.

Anyway, with all your data in Sheet1, the formula should read:

=IF(COUNTIF(Sheet1!$A$2:A2,Sheet1!A2)=1,Sheet1!A2,"")

RagDyer thank you. Now is there a way for it to count the number of records
relating to each , it has generated a list with blank in and I was going to
use the Cpearson code to remove the blanks. Would I be better running the
blank removal code, to generate a concise list and then putting code in the
cells adjacent to this list that would use some kind of count function
example below
col c

120260 if cell c1= not null count the columnA on sheet1 looking for values
=c1 on this worksheet i.e 120260

i have just this code to remove blanks in my column. It comes up with a #num!
error

=IF(ROW()-ROW(noblanks)+1>ROWS(blanks)-
COUNTBLANK(blanks),"",INDIRECT(ADDRESS(SMALL(
(IF(blanks<>"",ROW(blanks),ROW()+ROWS(blanks))),
ROW()-ROW(noblanks)+1),COLUMN(blanks),4)))

any ideas?

On Sheet2,
Place the "Extracting" Countif() formula in Column A,
Place the "Remove Blanks" *array* formula in Column B,
And the "Counting" Countif() formula in Column C.

That way, all you have to do is paste new data into Column A of Sheet1, and
you'll *automatically* get your desired return on Sheet2.

As far as the trouble you're having with the "Remove Blanks" formula;
Have you named all your ranges correctly and consistently?
Have you remembered that the formula is an *array* formula?
--
Array formulas are entered using CSE, <Ctrl> <Shift> <Enter>, instead of the
regular <Enter>, which will *automatically* enclose the formula in curly
brackets, which *cannot* be done manually.
