how to sort the values

Open Excel, click-on the half-inch diameter ribbon icon-thingy, click-on new/ blank-workbook create, mouse on down to the tabs at the bottom of the spreadsheet, delete sheet3 and sheet2. Then click-on Data tab back above, select "From text" button, mouse to the directory containing your textfile with the above data in it, choose open and when the dialog pops up choose delimited. Then choose, in the next panel "comma" delimiter.

Eventally choose "A1 ...ok".

And now you've got two columns of data.

Select all the data using your mouse, then, back under the "home" tab, choose "sort filter/custom filter" and when the dialog pops up, choose the column you want to sort on.

Once the list is appropriately plied, save the file as .txt.

Or whatever looks good or you find more useful than .txt.

[edit]

Close Excel.
