Sure, I can help you with that! Here are the steps to remove the connecting lines from a line chart in Microsoft Excel:

1. Select the line chart that you want to modify.
2. Click on the "Design" tab in the ribbon at the top of the screen.
3. Click on the "Change Chart Type" button in the "Type" group.
4. In the "Change Chart Type" dialog box, select the "Scatter" chart type.
5. Choose the subtype of scatter chart that you want to use (e.g. "Scatter with Straight Lines and Markers").
6. Click "OK" to close the dialog box and apply the changes to your chart.
7. Your chart should now display only data points without any connecting lines.

That's it! You should now have a scatter chart that displays your data points without any connecting lines. If you have any further questions or need additional help, feel free to ask.
