To get you started, you could do something like this
It uses your functions to add information to the second worksheet
You'll need to add the rest
I added a command buttion to run the sub
Also, I added your data and macro to make a XLSM workbook and attached it
It's MUCH easier if you do it that way instead of Google docs, etc. so PLEASE next time
Option Explicit
Dim wsText As Worksheet
Dim wsAnalysis As Worksheet
Dim sText As String
Sub SuperSub()
Set wsText = Worksheets("Texte à analyser")
sText = wsText.Cells(1, 1).Value
Set wsAnalysis = Worksheets("Analyse linguistique")
With wsAnalysis
.UsedRange.Clear
.Cells(1, 1).Value = "Number of letters in a string, ignoring punctuation, spaces and numbers"
.Cells(1, 2).Value = NombreDeLettres(sText)
.Cells(2, 1).Value = "Number of vowels in a string, ignoring punctuation, spaces and numbers"
.Cells(2, 2).Value = NombreDeVoyelles(sText)
End With
MsgBox "Done"
End Sub
