Here are the steps to insert a checkbox in Excel:

1. First, make sure that the Developer tab is visible in the Ribbon. If it's not visible, you can enable it by going to File Options Customize Ribbon, and then checking the box next to "Developer" in the right-hand pane.
2. Click on the Developer tab in the Ribbon.
3. Click on the "Insert" drop-down menu in the Controls group, and select "Checkbox" under the Form Controls section.
4. Click and drag to draw the checkbox where you want it to appear on your worksheet.
5. Right-click on the checkbox and select "Format Control" from the context menu.
6. In the Format Control dialog box, go to the "Control" tab.
7. Under the "Checked" section, select the "Checked" option.
8. Click OK to close the dialog box.

Now, when you click on the checkbox, it should get ticked. You can also copy and paste the checkbox to other cells in your worksheet.
