Re: Having partial text in a cell change to bold.

ScottF1870 If you have any version of Microsoft 365 except for Microsoft 365 Basic, you can use the desktop version of Excel on Mac and Windows. If you do not have that yet, you can install the local apps by logging in to https://www.office.com with your Microsoft 365 account and clicking the Install link.

The macro should work - I tested it using Excel in Microsoft 365 for Windows.
