Clean Data in Power BI

Question

i need help on cleaning this data. Currently I've no idea to clean this kind of data. I want to clean based on month and total per supplier. Thanks

Answer 1

1. Select the first 2 columns [No] and [Supplier]
2. On the tab Transform drop down Unpivot Columns and click on Unpipot Other Columns

This converts your wide pivot table into a long, stacked format that is ideal for further processing.

Answer 2

Another way you can achieve this is

1. Select all the date columns.
2. Click on the transform tab, under any column section, click on unpivot only selected columns
3. Kindly rename the Attribute column to date

If you need to split the date column into month and year 4. on the transform tab, under the text column section, click on Split Column , select "by delimiter" on the dialog box, select split at the left-most delimiter and click ok.

You will have your month and year columns as shown below

if your value column holds figure for amount/money you can transform the data type and replace the null values with zero using the replace values function when you right-click on the values column.

I hope this helps
