我是一个新手Perl用户。我需要关于在Perl中读写文件的帮助。
让我解释一下情况：例如，我有一个名为input.xls的文件，其中包含字符串、数字和下拉列表。工作表中的一些单元格是锁定的。
我想从input.xls文件中读取数据，并将其写入一个名为output.xls的新文件中。
我遇到的问题是，我无法保留从中读取的文件的格式。
即生成的输出文件不显示下拉列表，而输入文件中锁定的单元格也不出现在输出文件中。
此外，即使是输入文件的格式也会在输出文件中发生变化。例如，如果在输入文件中合并了单元格，则输出文件中的格式不会保持相同。请指导。
以下是我的代码供您参考:
#!/usr/bin/perl -w
use strict;
use Spreadsheet::ParseExcel;
use Spreadsheet::WriteExcel;
use Spreadsheet::ParseExcel::SaveParser;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
print qq[Content-type:text/html \n\n];
my $cs='Book2.xls';
# Open the template with SaveParser
my $parser = new Spreadsheet::ParseExcel::SaveParser;
#my $formatter=Spreadsheet::ParseExcel::FmtJapan->new();
my $template = $parser->Parse('e.xls');
my $sheet = 0;
my $row = 0;
my $col = 2;
# Get the format from the cell
my $format = $template->{Worksheet}[$sheet]
->{Cells}[$row][$col]
->{FormatNo};
# Write data to some cells
$template->AddCell(0, $row, $col, 1, $format);
$template->AddCell(0, $row+1, $col, "This is a hello world eg", $format);
#$format->{Lock};
# Add a new worksheet
# $template->AddWorksheet('New Data');
# The SaveParser SaveAs() method returns a reference to a
# Spreadsheet::WriteExcel object. If you wish you can then
# use this to access any of the methods that aren't
# available from the SaveParser object. If you don't need
# to do this just use SaveAs().
#
my $workbook;
{
# SaveAs generates a lot of harmless warnings about unset
# Worksheet properties. You can ignore them if you wish.
local $^W = 0;
# Rewrite the file or save as a new file
$workbook = $template->SaveAs('new.xls');
}
# Use Spreadsheet::WriteExcel methods
my $worksheet = $workbook->sheets(0);
# $worksheet->protect();
#$worksheet->write('A1:B1','=1+2');
#my $locked = $workbook->add_format();
# $locked->set_locked(1); # A non-op
#my $unlocked = $workbook->add_format();
#$locked->set_locked(0);
# Enable worksheet protection
#$worksheet->protect();
# This cell cannot be edited.
#$worksheet->write('A1:B1', '=1+2', $locked);
$worksheet->write($row+2, $col, "World2");
$workbook->close();
