Copy from Multiple Workbooks and paste final column based on criteria

[Romuline]

Hi folks, hopefully this is a very simple problem you can help me solve. Basically I have multiple workbooks (50+) whereby I need to consolidate the rows and columns data from each Source WB into a master workbook but the effort column needs to be pasted based on the column header.

The data is setup like this in each source WB with dates going out till the end of the year ( 1 workbook per week)

Source WB1

Date	Task	Name	This Week
12.01.16	A	Bill	1
12.01.16	B	Bob	2
12.01.16	C	John	0.5

<tbody>
</tbody>

Source WB2

Date	Task	Name	This Week
19.01.16	A	Bill	0.25
19.01.16	E	Bill	3

<tbody>
</tbody>

Source WB3

Date	Task	Name	This Week
26.01.16	A	John	1
26.01.16	C	John	1
26.01.16	E	Bob	2.5

<tbody>
</tbody>

Output to Master WB should be

Task	Name	12.01.16	19.01.16	26.01.16
A	Bill	1	0.25
E	Bill		3
B	Bob	2
E	Bob			2.5
A	John			1
C	John	0.5		1

<tbody>
</tbody>

Many thanks for any help provided
