A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
There are two types of Checkbox control available: Form Control and ActiveX. The Form Control checkbox does not have the ability to be Moved and Sized with cells. The ActiveX checkbox control does.
In the Developer tab, Controls group, click Insert and then choose the Checkbox control under ActiveX Controls.
Click in your worksheet at the desired location.
Right-click on the control > Format Control > Properties tab > Move and size with cells > OK.
To be able to use the checkbox, you need to switch off Design Mode (next to Insert on the devleoper tab).
Tip: to be able to snap the size of the control to be the same as the cell, insert a shape (Insert tab > Shapes > Rectange...) and then in the Drawing Tools > Format tab, in the Arrange group click Align > Snap to Grid. You can then resize the checkbox control so it exactly fits in a cell.
Hope that helps.
Cheers
