Transpose grouped columns

[pranaysharmadel]

I'm trying to transpose rows into columns for a given group.

My initial table looks like this with 13 columns 

Given

Surname

company

Liveemail

Contract Start

Contract End

Instructor Cost

LMS Course ID

Course Title

SMIP

Section

Start Date

End Date

- 

The final table groups rows by these columns - "Given Surname company Liveemail Contract Start Contract End".

The remaining columns gets appended to the same row with a suffix 1,2,3 added like this.

So, the final table looks like this - 

This is the power query I have so far.

#"Grouped Rows" = Table.Group(#"Changed Type", {"Given", "Surname", "company", "Liveemail", "Contract Start", "Contract End"}, {{"crscount", each Table.RowCount(_), Int64.Type}}),

The columns need to be dynamic, if there are 100 rows for a given group, there need to be 100 sets of columns added to the main table like "LMS Course ID1 Course Title1 SMIP1 Section1 Start Date1 End Date1" all the way to  "LMS Course ID100 Course Title100 SMIP100 Section100 Start Date100 End Date100"

How can I have the columns added in end of the grouped row?

Hi @pranaysharmadel ,

The real question is: Why do you want to do this with your data? You're moving it away from the optimal structure for storage and reporting.

It sounds like an XY Problem to me. Can you explain what you're actually trying to achieve with your data and output please?
