+rem  Editors such as Cursor and VS Code claim the .py extension via the per-user

+rem  instead of running it. .cmd is always executed by the shell, so this gets
+rem  the converter running without changing any file associations.

+rem  Drag a CSV onto this file to preselect it, or just double-click and pick
+rem  both files from the dialogs.
