With that solution, does it change your entire system to Hebrew, or keep it in English?
I'm not sure, as it was a long time ago that I messed around with that and never ended up doing that. When I want easy access to Hebrew in Excel, I wrote a macro to handle it where I can just put in how the Hebrew word sounds in English and it produces the Hebrew letters. I can then copy and paste by value to use whereever I want or keep it as is (see below). I had to make some decisions like making a=aleph and A=Ayin. Or Q for Kuf and K for Kof, with c for Tzadi (cadi). If you want to use it and prefer a different association you can mess with it yourself:
' Pass in a transliterated word and output the Hebrew word in Unicode
Function HebWord(word As String) As String
Dim letter(65 To 122) As Integer
Dim hWord As String, hebLetter As String, midWord As String
letter(97) = 1488 ' a = aleph
letter(101) = 1488 ' e = aleph
letter(98) = 1489 ' b = beis, veis
letter(103) = 1490 ' g = gimel
letter(100) = 1491 ' d = daled
letter(104) = 1492 ' h = hei
letter(118) = 1493 ' v = vov
letter(111) = 1493 ' o = vov (oh)
letter(117) = 1493 ' u = vov (ooh)
letter(122) = 1494 ' z = zayin
letter(72) = 1495 ' H = hes
letter(116) = 1496 ' t = tes
letter(121) = 1497 ' y = yud
letter(75) = 1498 ' K = kof sofit
letter(107) = 1499 ' k = kof
letter(108) = 1500 ' l = lamed
letter(77) = 1501 ' M = mem sofit
letter(109) = 1502 ' m = mem
letter(78) = 1503 ' N = nun sofit
letter(110) = 1504 ' n = nun
letter(115) = 1505 ' s = samech
letter(65) = 1506 ' A = ayin
letter(80) = 1507 ' P = pei sofit
letter(112) = 1508 ' p = pei
letter(67) = 1509 ' C = cadi sofit
letter(99) = 1510 ' c = cadi
letter(113) = 1511 ' q = kuf
letter(114) = 1512 ' r = reish
letter(83) = 1513 ' S = shin/sin
letter(84) = 1514 ' T = tof/sof
For char = 1 To Len(word)
midWord = Mid(word, char, 1)
Select Case Asc(midWord)
Case 65 To 90, 97 To 122
hebLetter = letter(Asc(midWord))
If hebLetter <> 0 Then hWord = hWord + ChrW(hebLetter)
Case Else
hWord = hWord + midWord
End Select
Next char
HebWord = hWord
End Function
I actually have this in a XLAM file which Excel refers to automatically (by going to File-->Options-->Add-ins-->Excel Add-ins, activate the XLAM add-in you created.)
I noticed just now that File > Options > Language indicates that you can add an additional (secondary) language to Excel. The first is the language Excel will use to display everything, and it could be that the additional language allows for other languages to be displayed after that. It says "Office display language. Buttons, menus, and other controls will show in the first available language on this list."
