I want a function like this:
to unmerge all merged cells in a Excel sheet and replaced all the merged
cells value with the originally merged area value after unmerging action.

I use the a cycle to fulfill it. But it's too too slowly if the Excel sheet
data is a little big. The code (c# code) as below:

for (int i=1; i<=Int32.Parse(ws.UsedRange.Rows.Count.ToString()) ;i++)
{
for (int j=1; j<=Int32.Parse(ws.UsedRange.Columns.Count.ToString ()); j++)
{
Excel.Range Range = (Excel.Range)ws.Cells[i,j];


if (bool.Parse(Range.MergeCells.ToString()))
{
int x = Int32.Parse(Range.MergeArea.Rows.Count.ToString()) ;
int y = Int32.Parse(Range.MergeArea.Columns.Count.ToString ());
string TempValue = Range.Text.ToString();

Range.MergeArea.UnMerge();

for (int m = i; m<(i+x); m++)
{
for (int n = j; n<(j+y); n++)
{
Excel.Range TempRange = (Excel.Range)ws.Cells[m,n];
TempRange.set_Value( Type.Missing,TempValue);
}
}
}

}
}


Does Somebody have another idea to do it quickly??
Thanks.

Pls help me :)

Why can't you just select all cells in the sheet (small square that
intersects headers), Format cells Alignment and untick the Merge cells box
(may need to click it twice). Record a macro for the code.

I might have misunderstood your original question, are you saying you want
to do something like this:

- First merged area is (say) B2:B5 and B2 contains value "X" (only B2 can
contain data)
- Unmerge B2:B5 and put "X" in the other 7 cells.
- Do similar with all merged areas on the sheet

Sub TestUnmerge()
Dim r As Range, rMgArea As Range

For Each r In ActiveSheet.UsedRange
If r.MergeArea.Cells.Count 1 Then
Set rMgArea = r.MergeArea
r.UnMerge
rMgArea.Value = r.Value
End If
Next

End Sub

This assumes by "value" you mean constants and not formulas. If not above
would need to be changed.

Dear Peter:
Because Range is a class in C#, so I can't use the Foreach statement as
in VBA code.
Finally, I use a replacement method to do the same thing. Though it is
lower than your method.
The C# code as below:

for (int i=1; i<=Int32.Parse(ws.UsedRange.Rows.Count.ToString()) ;i++)
{
for (int j=1; j<=Int32.Parse(ws.UsedRange.Columns.Count.ToString ()); j++)
{
Excel.Range Range =(Excel.Range) ws.UsedRange[i,j];
if (bool.Parse(Range.MergeCells.ToString()))
{
Excel.Range rMergeArea = (Excel.Range) Range.MergeArea;
Range.MergeArea.UnMerge();
rMergeArea.Value2 =
Range.Value2;
}
}
}

In a word, thank you very very much for your reply and guide for me.
And I'm very pleasure to make a friend with you. My mail is

Thanks for posting the C# code. Your comment that this is slower than VBA is
interesting, I had always been under the impression that VBA is slower.

I tested "For 1 to .UsedRange.Count" vs "For Each" with data in 1500 merged
areas in a UR of 10,000 cells. Both slow but virtually same time. So I don't
think the VBA vs C# speed difference is related to "For Each".

However I found this about twice as fast:

Sub TestUnmerge3()
Dim i As Long, n As Long
ReDim ay(1, 0)

With ActiveSheet.UsedRange
For i = 1 To .Count
If .Cells(i).MergeArea.Count 1 Then
If .Cells(i) < "" Then ' And .Cells(i).HasFormula = False '?
n = n + 1
ReDim Preserve ay(1, n)
ay(0, n) = .Cells(i).MergeArea.Address
ay(1, n) = .Cells(i).Value
End If
End If
Next
..UnMerge
End With
For i = 1 To n
Range(ay(0, i)).Value = ay(1, i)
Next
End Sub

Even with all the array stuff, taking '.UnMerge' [each single mergearea] out
of the loop seems to give a dramatic speed improvement.

Peter
