My data are in long format, like below, now. I am wondering should I convert it to a short format and then import it to Power BI to do the analysis and visualization? Thanks!
ID | Indicator | Value |
1 | Sales | 615 |
1 | Costs | 55 |
1 | Profits | 500 |
2 | Sales | 100 |
2 | Costs | 2 |
2 | Profits | 98 |
3 | Sales | 45 |
3 | Costs | 3 |
3 | Profits | 42 |

@Anonymous , I am not very clear on the Long format. But seem like you have measure/columns/kpi as rows. If they are not too many unpivot.

Usually, we have sales, cost, and profit as columns.
But current format has its own advantage and disadvantages.

Thanks, amitchandak. You already answered my question. I just want to know what is the best format of data to do visualization in PowerBI.
@Anonymous what is your definition of short and long. Fact tables are always thin and long and dimension tables can be wide and short.
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!

Hi, Parry2k, thanks for your reply.
My definition of short format is that: each indicator is in one column and each row is for each subject (ID). In other words, a subject’s repeated responses will be in a single row, and each response is in a separate column.
My definition of long format is that: as the table I showed, each subject (ID) will have data in multiple rows.
