Leave Helpful comments with Cell Notes

Problem: I have figured out how to write a confusing formula in Excel. I want to add a note to the worksheet to remind myself how the formula works.

Strategy: You can use cell comment to leave notes in a worksheet. In addition to having 17 billion cells on a worksheet, you can also store a notet for each cell. Typically, a cell comment is indicated by a red triangle in the corner of the cell. If you hover the mouse over the cell, the comment will appear.


A complicated formula in the formula bar calculates the number of Friday the 13ths between two dates.

Here’s how you add comments to a worksheet:

  • 1. Select the cell where you want to add a comment. Select Review, Notes, New Noth. A note box appears, with your name in bold on line 1.

By default, a note starts with your name in Bold and the flashing insertion point on the next line.

  • 2. Type a note.

  • 3. Click the mouse outside the note box to complete the entry of the comment. A red triangle remains in the cell to indicate the presence of a note there.

Type a note: This formula concatenates the serial number of the two dates to form an array.

When you hover your mouse over the cell with the red triangle, your note box will pop up like a ToolTip.

Additional Details: To delete a note, you select the cell and then select Review, Delete. To edit a note, you select the cell and then Edit Note will be available in the Review tab.

Any time someone hovers over the red triangle in the cell, the yellow post-it note appears with the note.

The information here is based on the assumption that you are using the default settings for notes. There are additional settings available in the Advanced tab of the Excel Options dialog. On this tab, for example, you can suppress the appearance of the red note indicator or force all notes to be shown at all times.

Excel Options, Advanced. For Cells With Comments, show:
The three choices are:
No Comments or Indicators
Indicators Only, and Comments on Hover (default)
Comments and Indicators

Gotcha: If you have a note in a row above the Freeze Panes line, you will notice a bug. The note will appear normally if you have scrolled the worksheet to the top. However, if you have scrolled down to other pages in the worksheet, the note will be truncated.
