How do I make vba code compatible with libre office

Question

I have recently migrated to pclinuxos from windows and seem to like it. The only problem I am facing is that libreoffice, the default spreadsheet package is not compatible with excel macros. Below is the vba code I have:

Option VBASupport 
Sub DeleteToLeft()
    Selection.SpecialCells(xlBlanks).Delete shift:=xlToLeft
End Sub
Function SinceLastWash()
    Application.Volatile
    WashCount = 0
    WearCount = 0
    CurrentRow = Application.ThisCell.Row
    For i = 3 To 35
        If Range(Cells(CurrentRow, i), Cells(CurrentRow, i)).Value = "a" Then
            WearCount = WearCount + 1
        End If
        If Range(Cells(CurrentRow, i), Cells(CurrentRow, i)).Value = "q" Then
            WashCount = WashCount + 1
            WearCount = 0
        End If
    Next i
    SinceLastWash = WearCount
End Function
Function testhis()
testhis = Application.ThisCell.Row
End Function

Is there a way to convert this code to make it compatible with libreoffice or do I have to learn an altogether new language like python? Learning python would not be a problem but is not a solution to my problem as I have many work related files in excel which have a lot of vba code and it is not possible for me to use open office/libreoffice at work...

I just want to add that the function SinceLastWash gives the correct value in some cells where I use it and in others gives an error, #NAME?

Thanks

From LibreOffice's online help file:

With a few exceptions, Microsoft Office and LibreOffice cannot run the same macro code. Microsoft Office uses VBA (Visual Basic for Applications) code, and LibreOffice uses Basic code based on the LibreOffice API (Application Program Interface) environment. Although the programming language is the same, the objects and methods are different.

The most recent versions of LibreOffice can run some Excel Visual Basic scripts if you enable this feature at LibreOffice - PreferencesTools - Options - Load/Save - VBA Properties.

In reality, you would most likely need to sit down with the LibreOffice API and rewrite the functionality.
