Converting List to Meaningful Data

Hi,

I have this table:

Date	A	B	C
5-Jan	9	43	133
6-Jan	2	48	118
Date	B	D	A
7-Jan	17	1050	7
8-Jan	14	1257	4

The desired output looks like the following:

Date	Item	Value
5-Jan	A	9
5-Jan	B	43
5-Jan	C	133
6-Jan	A	2
6-Jan	B	48
6-Jan	C	118
7-Jan	A	7
7-Jan	B	17
7-Jan	D	1050
8-Jan	A	4
8-Jan	B	14
8-Jan	D	1257

How do you suggest I go on about this? Unpivoting obviously doesn't work.

PiyushBQ unpivot should work and is the solution.

- transform data
- select date column in the table table
- right-click, unpivot other columns it will add two columns, attribute, and value, rename these as per your requirement
- close and apply

To visual, take table visual, put date, attribute, and value to see the result.

I would ❤ Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!
