Some notes from previous messages on this topic:

As the macron normally denotes a long vowel, there is no such glyph in
Unicode. However, there are combining diacritical marks in Unicode, and
the macron is x0304.

Steps:
Run Charmap; select font Lucida Sans Unicode; Go to Unicode: 0304;
press Select, Copy.

Run Notepad; type xCtrl+v. (That is the letter x followed by Ctrl+v)
This will create an x+macron.
Ctrl+a Ctrl+c will Select All and Copy.

Run Excel; in a cell, Ctrl+1 and select Font Lucida Sans Unicode;
Ctrl+v - voilà.

Maybe this tip from Debra Dalgleish will help:

There is the Private Character Editor supplied with Windows.
You can create custom characters with it and make them part
of one or more fonts.
In "Run" enter: eudcedit.exe
You will have to read the help file.
