Dear monks!

I think the following discovery might be useful for you:

I openend an Excel-workbook to extract some data, as instructed in the node above:

...
my $Book  = $Excel->Workbooks->Open($excelfile);
my $Sheet = $Book->Worksheets("Sheet1");
...
[download]

The resulting investigation showed that this special file contained very complex pivot-tables. As a result, opening it seems not to be finished when I tried to access the worksheet. Strange. Fortunately, this could be solved very easily with the following code:

...
my $Book  = $Excel->Workbooks->Open($excelfile);
sleep(1);                                            # give Excel time
+ to open the file
my $Sheet = $Book->Worksheets("Sheet1");
...

Hope this node helps you (and saves you some debugging-time) in case you encounter the same situation!
