perl - 如何使用OLE模块处理Excel？

Question

friend 们，我编写了一个 Perl 脚本来将一组 CSV 文件转换为电子表格 使用 Spreadsheet::WriteExcel 格式化。经过一番研究后我发现 结论是没有选项可以将列宽固定为自动调整选项。

所以我正在做的是在使用 Win32::OLE 打开该 XLS 文件的同一个脚本中 模块，在执行此操作时我收到一条错误消息

Can't use an undefined value as a HASH reference

对应的代码是:

# spread sheet creation
my $workbook  = Spreadsheet::WriteExcel->new($file_name);
# ...
my $worksheet = $workbook->add_worksheet($work_sheet_name);
# ...
$worksheet->write($rowNum, $j,$_,$default_format);

完成这些步骤后，我在同一脚本中添加了更多行:

my $Excel = Win32::OLE->GetActiveObject('Excel.Application')
    || Win32::OLE->new('Excel.Application');
$Excel->{'Visible'} = 0;    #0 is hidden, 1 is visible
$Excel->{DisplayAlerts}=1;  #0 is hide alerts

# Open File and Worksheet
my $return_file_name="C:\\Users\\admin\\Desktop\\Report_Gen\\$file_name";
print ">>$return_file_name<<";
my $Book = $Excel->Workbooks->Open($return_file_name); # open Excel file
foreach my $Sheet (in $Book->Sheets) {
    my $LastCol = $Sheet->UsedRange->Find({What=>"*", 
        SearchDirection=>xlPrevious,
        SearchOrder=>xlByColumns})->{Column};    # mentioned error is from this line
    my $mylastcol = 'A';
    for (my $m=1;$m<$LastCol;$m++) {$mylastcol++;}
    my @columnheaders = ('A:'.$mylastcol);
    foreach my $range (@columnheaders){
        $Sheet->Columns($range)->AutoFit();
    }

Answer 1

I wrote a Perl script to convert a set of CSV files into spreadsheet format using Spreadsheet::WriteExcel. After some research I came to conclusion that there is no option to fix column width as Auto-fit option.

自动调整是 Excel 中的运行时选项，因此无法使用 Spreadsheet::WriteExcel 通过文件格式创建它。

但是，Spreadsheet::WriteExcel 文档包含 an example of how to simulate autofit并对所涉及的一些问题进行了解释。
