Saskia was having a problem converting information, under the control of a macro, and still having it be usable in Excel. When she would receive a worksheet that showed numbers formatted with decimal points, she would need to convert the values so they used decimal commas, consistent with how numbers are displayed in Holland. She would do a find and replace, and everything would work fine. However, when she recorded a macro that did the find and replace, the resulting cells were treated as text instead of as numeric values.
The reason for this behavior is that Excel VBA "speaks" American, and some actions done using a recorded macro don't work as expected due to that fact. Because American Excel expects the decimal separator to be a period, interpreting a "number" in VBA with another separator (such as a comma) will cause Excel to consider the value to be text.
The workaround is not to use find and replace, but to use a different trick. Consider the following short macro:

Sub ConvertNumbers()
Dim oConRange As Range
Set oConRange = ActiveSheet.UsedRange.Cells.SpecialCells(xlConstants)
oConRange.Value = oConRange.Value
End Sub
This macro defines a range that consists of all the cells that contain constants. Then, it sets the value of each cell in the range equal to itself. In the process of doing this, Excel re-evaluates the contents of each cell and converts it to the appropriate numeric value. In other words, numbers that contain decimal points are converted to numbers that contain decimal commas.
There are other ways you can process the cells using a macro, but the above procedure seems to work the best and the quickest.

Take care. This is a very dangerous macro. When you have not a continuous block of cells with data in it (have some empty cells in a range, or some solitary cells anywhere on the sheet) then the contents of one or more cells is overwritten with the contents of another cell.

Hi,
In a user form chainging EXCEL´s configuration from "," to "." it works fine (interprets comma decimal point entered as numeric.
Is there a way to change (VBA) EXCEL configuration from comma to point and before exit change it back... Just for this one an only workbook.
thanks and best regards,
Héctor
