Importing an excel table into Power BI - Convert to List?

Hi,

I have data in an excel file that I want to import into a Power BI report, unfortunately the data is in a table not a list. 

For example:

Product    Jan 2020   Feb 2020    Mar 2020

20404        £13.42       £12.00         £12.50

20200        £6.77         £7.00           £7.25

How do I import this data as a list so:

Product      Month         Price

20404          Jan 2020      £13.42

20404          Feb 2020      £12.00

20404          Mar 2020      £12.50

20200          Jan 2020       £6.77

20200          Feb 2020       £7.00

20200          Mar 2020      £7.25

Is there a DAX function that I can use when importing the data that will do the conversion? Or would it be better to import each month individually and combine the data in Power BI using an append query? (Seems a long winded solution to me)

Thanks
