Record the date after matching the names

T

Tom

Hi,

My namelist.xls contains 10 stock codes for example - ABC, DEF, ....., XYZ
in the first column. How can I match these names against the closing
pricelist, 20060912.csv which contains the date and the closing prices, so
that if there is an exact match (not ABCD) it will record the corresponding
date (or otherwise a blank) in the second column of namelist.xls?

To make it clear, the date field is the second element of the closing
pricelist as shown below:

AAC,20061204,1.85,1.86,1.85,1.86,33383
AAE,20061204,.415,.48,.405,.445,294925
ABC,20061204,43,43,43,43,0
ABCD,20061204,.22,.22,.21,.21,96000
ACG,20061204,10.21,10.52,10.2,10.46,2920359
<snip>........

Much appreciate for any help.


TIA
Tom

PS. For those who enjoy challenges, after that, close 20060912.csv and
incrementally open up the next pricelist, namely 20060913.csv and do the
match again, recording the date along the next, i.e. third column. Do that
for N = 1 to N = 10.

Say your name list is on Sheet1, A1 to A10, and you've pasted the csv to
Sheet2, from A1 down.

Try this *array* formula in B1 of Sheet1:

=INDEX(MID(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)+1,8),MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0))

--
Array formulas must be entered with CSE, <Ctrl> <Shift > <Enter>, instead of
the regular <Enter>, which will *automatically* enclose the formula in curly
brackets, which *cannot* be done manually. Also, you must use CSE when
revising the formula.

*After* the CSE, copy down to A10.

If *no* match is found, you'll get a #N/A error returned.

If you really don't want to see the error message, and would prefer a blank
cell returned, the error trap makes this *array* formula "kind of bigger":

=IF(ISNA(MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0)),"",INDEX(MID(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)+1,8),MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0)))

Don't forget the CSE for this one also!

I must thank you for your effort but unfortunately something was not right.
There was not a single match when there ought to be. What is this A$1:A$5?

A$1:A$5 is the size of the range of names that you used in your OP.

It must be replaced with the *actual* cell references of your datalist (name
list).

I used it strictly as an example for you to try on your posted test data!

Since you didn't mention the size and location of your real data, I had to
use "something" to illustrate the workings of the suggested formula.

I might have (should have) mentioned to <<"adjust ranges to suit">>.

That was a neat way of extracting the date (the second element). One last
question. What would I have to change in the formula in order to extract the
sixth element, a decimal number, which can range from 0.001 to 999.999?
Thanks again for your help RD.

Sorry for the delay, too much work ... not enough time to play in this sand
box!<bg>

Also, no time to look for shorter options, but this works for me:

No error trap, returns text:
=INDEX(MID(Sheet2!A$1:A$5,FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5))+1,(FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",6))-FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5)))-1),MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0))

For XL recognizable numbers, add double unary in front of Mid() function:
=INDEX(--MID(Sheet2!A$1:A$5,FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5))+1,(FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",6))-FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5)))-1),MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0))

With error trap, returns text:
=IF(ISNA(MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0)),"",INDEX(MID(Sheet2!A$1:A$5,FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5))+1,(FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",6))-FIND("^",SUBSTITUTE(Sheet2!A$1:A$5,",","^",5)))-1),MATCH(A1,LEFT(Sheet2!A$1:A$5,FIND(",",Sheet2!A$1:A$5)-1),0)))

Just add unary if you want numbers.

Don't forget, these are *array* formulas.

It seems to capture the data correctly for the few cells of data tested. I
have yet to test the rest, which is up to 1240 cells. If they tested ok I
can dispense with an old macro procedure which matches and records each of
the names and corresponding data sequentially. Thanks once again, RD that
was wonderful.

That's a complex but clever formula. It works completely. I am more at home
with the old Excel macro. Since I left the scene, I have not bothered
keeping up with the changes when Microsoft introduced VBA for use with
Excel. But you have now made me want to pursue it further. Can you recommend
a good comprehensive text that I can get my hand on? Thanks.

Regards,
Tom
