Adding Diagonal Borders

by Allen Wyatt
(last updated October 17, 2020)

Excel allows you to add all sorts of borders to cells in a worksheet. You can place borders on the left, right, top, and bottom of a cell. If you select a range of cells, you can add borders to the left, right, top, bottom, and in between, meaning that the borders could be between cells within the selected range.

Many people don't realize that you can also place diagonal borders. This means that a border can appear from the top-left to the lower-right corners of a cell, or from the top-right to the lower-left. To take advantage of diagonal borders, follow these steps:

  1. Select the cell you want to have the diagonal border.
  2. Display the Home tab of the ribbon.
  3. Click the Format tool (in the Cells group) and then click Format Cells. Excel displays the Format Cells dialog box.
  4. Make sure the Border tab is selected. (See Figure 1.)
  5. Figure 1. The Border tab of the Format Cells dialog box.

  6. At the bottom left and right corners of the Preview area of the dialog box you should see buttons that have diagonal lines on them. Click the line that represents the type of diagonal border you want to use.
  7. Click on OK.

Diagonal borders can only be applied to cells, not to rectangular areas you select onscreen. For instance, if you choose cells A5:C12, the diagonal border won't go from the top-left corner of cell A5 to the bottom-right corner of cell C12. Instead, it is applied to the individual cells within the selected range.

Allen Quote "Diagonal borders can only be applied to cells, not to rectangular areas you select onscreen."

Actually you can draw a slanted line through an area with a little work. Simply select the diagonal cell using the control key and the left mouse button.
Then format the cell with the diagonal line of choice, voila!
If you want an 'X' than select the opposite diagonal cells and the opposite diagonal line and presto, you have an 'X'.

I highlighted all the cells and put a full border around it to highlight the 'Xed' out cells.
Of course it does have some limitations with the shape of the rectangle, but it will work for some.

(see Figure 1 below)

Roy, you win with 4 steps.
Michael 5 steps
Allan 6 steps
Note: In Roy's plan, Ctl-1 must be done with the numeric row at the top of keyboard. The numeric key pad did not work.

@Allan: Um, I guess you mean simpler than the tip. Not "simple" but "simpler than (fill in the blank)"?

For "simple" select the cell, press Ctrl-1, borders, and click the diagonal control. Couple steps to the thing to click beats four steps and not using the Ribbon for anything buried in its sub-menus is absolutely simpler and less work. If it's in the top level of the Ribbon menuing (yeah, its a menu, not something unique MS), that still takes a pair of clicks if you hate having a menu that covers an eighth of the screen, or more.

By the way, of course one can have diagonals in a range, but you have to select the cells it goes in using Ctrl-click and format, or format one, then copy and paste to the others. Last is easiest, but hard to do if you have content and/or they are not uniformly formatted.
