Here's the problem. This assigns the number of elements in @_ to the $self
variable. So $self is not an object, it's 2.
> #if (@_) { my $sheetname = shift; }

This pops the first element off of @_ - which is what you wanted in $self.
Another way to write these lines:
my ($self, $sheetname) = @_;
Another:
my $self = $_[0];
my $sheetname = $_[1];
And another:
my $self = shift;
my $sheetname = shift;
