Creating a to-do list in Excel 2010 is as simple as clicking on the cells you want to enter data into and typing the data. Users can move to new cells by either clicking on them or hitting the enter or tab keys on the keyboard.
More advanced features can help format the spreadsheet to the user's liking. To format the contents of cells, select these cells by dragging the mouse over them or by using the shift key to select a range. Then, either press CTRL + 1, right click and select Format Cells, or click the dialog box launcher next to Number under the Number group of the Home tab. In this menu, users can select what kind of data is in each cell and how to format the cells. For a to-do list, the Text option is likely the best choice.
You can apply borders from the Border tab of this same menu. It is also possible to select this menu from the Font group on the Home tab. Apply shading as desired under the Font group of the home tab. A button with a paint bucket that reads Fill Color has a drop-down arrow next to it that allows for the selection of a shading color.
