Winim Excel

[alfrednewman]

Hello,

Considering that I am a Windows user (since my childhood... just kidding), and 
considering I was in great need of a way to work with Excel files, I am very 
happy to have discovered Winim.

Practically all my problems are over! Great work @khchen !!

However, I have a question: given the code below 
[https://github.com/khchen/winim/blob/master/examples/com/Excel_Application2.nim](https://github.com/khchen/winim/blob/master/examples/com/Excel_Application2.nim)
    
    
    import strutils
    import winim.com
    
    comScript:
      var obj = CreateObject("Excel.Application")
      obj.visible = true
      obj.workbooks.add()
      
      var
        s1 = "the quick fox jumps over the lazy brown dog".split(" ")
        s2 = @[@[1, 2], @[3, 4, 5, 6, 7], @[8, 9, 10, 11], @[12], @[13, 14, 15]]
      
      obj.activeSheet.range("A1:E6").clear()
      obj.activeSheet.range("A1:I1") = s1 # this convert seq to 1D safearray
      obj.activeSheet.range("A2:E6") = s2 # this convert seq to 2D safearray
      
      COM_FullRelease()
    

How do I save the worksheet that was created in memory?
