Transform multiple columns based on values in another column

Anonymous — Mon, 08 Jul 2024 17:51:11 GMT

Hello,

I am trying to group, split, or somehow transform multiple columns (Years 2020-2023) based on values in another column (Source) for visualization in Power BI. The original data comes from Excel. How can I do the following?

This is the raw data I have right now, where I have multiple orders per customer, and each order being estimated based on Source A, B, and C. Specifically, I have 3 orders from Customer 1, and rows 2-4 are about the 1st order. In these 3 rows, values are the same for columns aaa, bbb, ddd, eee, fff, and ggg, so it is essentially a repetition. I have numbers in columns 2020-2023, but I don't want to view Source horizontally. Instead, I would like to incorporate Source into the Year columns.

This is the end product I want. Each order is only 1 row, and Source is incorporated into the Year columns such that I have 2020A, 2020B, 2020C, 2021A... and so on.

Really appreciate your help. Thanks!

** Update **

Raw Excel data I have currently:

aaa	bbb	Customer	ddd	eee	fff	ggg	Source	2020	2021	2022	2023
a1	b1	Customer 1	d1	e1	f1	g1	Source A
a1	b1	Customer 1	d1	e1	f1	g1	Source B
a1	b1	Customer 1	d1	e1	f1	g1	Source C
a2	b2	Customer 1	d2	e2	f2	g2	Source A
a2	b2	Customer 1	d2	e2	f2	g2	Source B
a2	b2	Customer 1	d2	e2	f2	g2	Source C
a3	b3	Customer 1	d3	e3	f3	g3	Source A
a3	b3	Customer 1	d3	e3	f3	g3	Source B
a3	b3	Customer 1	d3	e3	f3	g3	Source C
a4	b4	Customer 2	d4	e4	f4	g4	Source A
a4	b4	Customer 2	d4	e4	f4	g4	Source B
a4	b4	Customer 2	d4	e4	f4	g4	Source C
a5	b5	Customer 2	d5	e5	f5	g5	Source A
a5	b5	Customer 2	d5	e5	f5	g5	Source B
a5	b5	Customer 2	d5	e5	f5	g5	Source C
a6	b6	Customer 2	d6	e6	f6	g6	Source A
a6	b6	Customer 2	d6	e6	f6	g6	Source B
a6	b6	Customer 2	d6	e6	f6	g6	Source C
a7	b7	Customer 2	d7	e7	f7	g7	Source A
a7	b7	Customer 2	d7	e7	f7	g7	Source B
a7	b7	Customer 2	d7	e7	f7	g7	Source C
a8	b8	Customer 3	d8	e8	f8	g8	Source A
a8	b8	Customer 3	d8	e8	f8	g8	Source B
a8	b8	Customer 3	d8	e8	f8	g8	Source C

And this is the end result I am looking for:

aaa

bbb

Customer

ddd

eee

fff

ggg

2020 A

2020 B

2020 C

2021 A

2021 B

2021 C

2022 A

2022 B

2022 C

2023 A

2023 B

2023 C

Customer 1

Customer 2

Customer 3

Thank you!

hi Anonymous ,

Create a blank query , copy and paste the below code into the advanced editor.

Output:

The last step would be the structure the Merge and Value column as needed etc.

However, I recommend you load it as is in Power query and use a matrix visual instead for the same.

If the goal is to create a pivot table using Power query or similar , refer to Subtotal and Column Total in Power Query - YouTube

Thank you! I would need to use a table instead of matrix for the visualization.

Based on the output you provided, how can I merge the rows in the same order (ex: the a1s, the a2s) into one row, with the Merged column expanded as multiple columns?

This is what I'm referring to:

aaa

bbb

Customer

ddd

eee

fff

A2020

A2021

A2022

A2023

B2020

B2021

B2022

B2023

...

Customer 1

Sorry for the back and forth... I received an expression error saying "Expression.Error: A cyclic reference was encountered during evaluation."
