ungroup table, manipulate columns and convert to a row

I have an Excel table (can be converted to XML or CSV for manipulating) of this structure:

| License-plate | Parking | Fuel | Cleaning |
---------------------------------------------
| 1111AAA       | 234     | 21   | 1244     |
| 2222AAA       | 22      | 12   | 644      |
| 3333BBB       | 523     | 123  | 123      |

Which is a monthly spending for parking, fuel, etc. per car/month.

License plate is unique value in the table.

I need to convert this table in this to import it to MySQL, but I don't know how to do that and which tool is good for it:

| License-plate | Concept  | Amount |
-------------------------------------
| 1111AAA       | Parking  | 234    |
| 1111AAA       | Fuel     | 21     |
| 1111AAA       | Cleaning | 1244   |
| 2222AAA       | Parking  | 22     |
| 2222AAA       | Fuel     | 12     |
| 2222AAA       | Cleaning | 644    |
| .......       | ........ | .....  |

In the result table License-plate is not the unique value, and it's repeated for the number of concepts it have.
