Excel: How to extract group of the same rows and their values into columns?
How can I extract the second table from the first one? I need to extract those titles that have exactly three costs (in the following example: f1 and f3). I tried using pivot tables but could not manage to generate the second table. Any advice would be appreciated!
UPDATE: I appreciate that Mike Honey offered a solution. However, since I'm not familiar with Power Query language at all, I am looking for a solution that uses no Add-ins.
There is some general resemblance between this problem and: Excel 2007 transpose/combine multiple rows into one; How to combine values from multiple rows into a single row in Excel?; and excel-2010-move-data-from-multiple-columns-rows-to-single-row. However, this problem differs in that the requirement is not just to transpose and aggregate data, but to do it only for those titles with exactly three costs.
Solution 1:
I would resolve this with the Power Query Add-In. It takes a few steps to get there and a bit of coding in the Power Query language (M) to generate the "running count" needed to get the "cost1/2/3" column headings, and more M code to call the Table.Pivot function (it's not exposed in the Power Query UI).
I've built a prototype which you can view or download - its "Power Query demo - Pivot rows into columns with Running Count.xlsx" in my One Drive:

Basically my technique was to add a calculated column to get the "Cost Title" e.g. cost1/2/3. To get this I needed to write a "Running Count" function, to return an Index that resets for each group (title).
I got the outline for the "Running Count" function from this blog post - under "Year-to-Date Sales":

Then I used the Table.Pivot function to generate a column for each unique value in the destination column.
The documentation for Table.Pivot is here:

Another example of using Table.Pivot is here:

Finally I filtered out the rows with nothing for cost3.
