Need help populating a table of dates & times

[KellyD13]

Hi,
Sorry, but if someone could help me here I would be grateful.

I have a table with the following values:

<TABLE style="WIDTH: 152pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=203 border=0><COLGROUP><COL style="WIDTH: 56pt; mso-width-source: userset; mso-width-alt: 2742" width=75><COL style="WIDTH: 48pt" span=2 width=64><TBODY><TR style="HEIGHT: 48pt;

Many thanks in advance.

Welcome Kelly,

In order to lookup the most recent reading for each Date-Time combination, you should have one column in each table that uses the complete Date-Time value.

Assuming that your existing data table has only Dates in the first Column and only decimal values for the Time in hours in the second Column, you can add a Date-Time column using the formula shown in Cell A2 below.

Now use Vlookup with the "True" parameter (approximate match) to read the values into your new table.

Excel Workbook
	A	B	C	D	E	F	G	H	I
1	Date-Time	Date	Time	Value		Date-Time	Date	Time	Value
2	4/2/2011 18:00	4/2/2011	18.00	-1.96		7/2/2011 10:00	7/2/2011	10:00	-1.96
3	7/2/2011 11:00	7/2/2011	11.00	-1.49		7/2/2011 11:00	7/2/2011	11:00	-1.49
4	7/2/2011 19:00	7/2/2011	19.00	-1.67		7/2/2011 12:00	7/2/2011	12:00	-1.49
5	8/2/2011 11:00	8/2/2011	11.00	-1.72		7/2/2011 13:00	7/2/2011	13:00	-1.49
6	8/2/2011 19:00	8/2/2011	19.00	-1.89		7/2/2011 14:00	7/2/2011	14:00	-1.49
7	9/2/2011 11:00	9/2/2011	11.00	-1.66		7/2/2011 15:00	7/2/2011	15:00	-1.49
8	9/2/2011 19:00	9/2/2011	19.00	-2.02		7/2/2011 16:00	7/2/2011	16:00	-1.49
9	10/2/2011 11:00	10/2/2011	11.00	-1.72		7/2/2011 17:00	7/2/2011	17:00	-1.49
10	10/2/2011 18:00	10/2/2011	18.00	-1.18		7/2/2011 18:00	7/2/2011	18:00	-1.49
11						7/2/2011 19:00	7/2/2011	19:00	-1.67
12						7/2/2011 20:00	7/2/2011	20:00	-1.67
13						7/2/2011 21:00	7/2/2011	21:00	-1.67
14						7/2/2011 22:00	7/2/2011	22:00	-1.67
Sheet1

I found that I needed to add one second to the value in cell F2 (7/2/2011 10:00:01 AM) to ensure that Vlookup worked correctly when times appeared to match between the two tables. I believe this was due to extremely small differences in rounding of the calculated times.

JS411,

Many thanks for your quick reply.

That seems to work a treat, its Sat night here, so I will do more work on it tomorrow evening.

I am extremely grateful, it will take light years off what I am trying to do.

Cheers
