To unpivot columns C:M in Excel, you can use the Power Query feature. Here are the steps:

1. Select your data and convert it into a table by going to the “Insert” tab and clicking on “Table”.

2. With the table selected, go to the “Data” tab and click on “From Table/Range” in the “Get & Transform Data” group. This will open the Power Query Editor.

3. In the Power Query Editor, select the columns you want to keep static. In your case, if columns A and B are not part of the unpivot operation, select these columns.

4. After selecting the static columns, go to the “Transform” tab and click on “Unpivot Columns” > “Unpivot Other Columns”. This will unpivot all columns other than the ones selected.

5. Click on “Close & Load” in the “Home” tab to load the unpivoted data back into Excel.

Please note that Power Query is available in Excel 2010 or later versions1. If you’re using an older version of Excel, you might need to use a different method.
