Excel Project Gantt Chart: Adding Milestone Diamond

Occasional Contributor

Hello, I am trying to put a diamond shape in my excel project from: How to Make the BEST Gantt Chart in Excel (looks like Microsoft Project!) - YouTube

On 9:21.

Can someone please help me why this is not working? ↓

It looks like the Wingdings font is not installed or damaged on your computer.

You can try the Symbol font, turn on Num Lock, and press Alt+0168 using the number keypad.

If you're willing to use a bullet instead of a diamond, set the font to the standard font of your worksheet (probably Calibri or Arial), turn on Num Lock, and press Alt+0149 using the number keypad.

I have tried that but it doesn't seem to be working.
And I have tried it on multiple computers.


I have attached a sample workbook. This is what I see in it:


What do you see when you open it?

The same thing. I don't understand why it isn't working for just the Gantt chart


Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar? Alternatively, you can attach it to a private message to me. Thanks in advance.

I have received the workbook. The problem was not in the character, but in the formula.

The formula in J6 should be




with the font set to Wingdings. Fill to the right and down. See the attached version.

Thank you soo much!
