This can be especially useful if you are tracking multiple tasks or items in a single sheet, as it allows you to quickly and easily see which items have been completed and which still need to be done. Additionally, adding a checkbox to a sheet in Smartsheet can help you to quickly and easily filter and sort your data, allowing you to quickly and easily find the information you need.
