To enter data in Excel, click a cell and type the data. Press Enter to move to the next cell down or Tab to move right. Text that exceeds the column width will be hidden. You can resize columns by dragging the column boundary. You can insert or delete rows and columns by right clicking. You can move or copy data by dragging and dropping or copying and pasting. Formatting in Excel is similar to Word - you select cells first before applying formatting like changing the number format. The fill handle allows filling cells with a series by dragging from two selected cells.
