Transposing a single column to multiple rows

I have a large sheet containing data from daily calibrations of an instrument for the last quarter (April 1 to June 30). When imported to Excel (2007) from the .csv file, it has three columns: Date, Time, and Value. Each calibration is between 10 and 22 minutes long, data is collected each minute, and some days have more than one sequence.

I was wondering if anyone knows a way to automatically transpose the Value column into multiple rows (on a separate sheet), where each new row starts at the beginning of each new calibration. I did it manually, selecting each segment of data and doing copy>paste special>transpose, and it took me quite a while so I’m hoping there’s a quicker way for when a similar report needs to be done, which may be this week for a different instrument.

I’ve attached an example file, where the first sheet is the data imported from the .csv file and the second sheet is the format I’m hoping to get the data into. I’ve highlighted each calibration sequence in the first sheet with a different color to better define where each starts and stops. Entering the dates and start/stop times into the desired format manually shouldn’t be too bad, so automatically transposing the Values is really all I need to figure out. But of course if there’s an easy way to do the dates and times that would be lovely.

For an engineering student, I’m pretty useless when it comes to Excel.

Thanks in advance for any responses! I may be in and out of my office for a while today, but I’ll try to answer any clarification questions in a timely manner.

You could achieve this in Access using a cross tab query. If you don't have Access available to you, then you could use the built in Query Functionality of MS Query (included in Excel). Click on the link below for a tutorial on MS Query.

Here is the SQL statement for MS Query

You could try with formulae, but the workbook might be a bit slow with large amounts of data due to the array formulae required.

See this workbook

Based on marcol's idea, this version does not use array formulas and should stay pretty robust no matter how big the data set is.

Hmm?
@ Jerry
Your formula seems to omit the last value in each set, to early for me to workout why ...

Here's another, longer, version without using CSE arrays.

Thanks Marcol.

The formula in B3, then copied across the table should be:

=IF($A3="", "", IF(E$2<=INT(($D3-$C3)*1440)+1, INDEX('Calibration Data'!$C:$C,MATCH($A3+0.01,'Calibration Data'!$D:$D,0)+E$2-1), ""))
