Perl：将数据从哈希转储到 Excel 中

使用Perl编程语言将数据从哈希转储到Excel是一项常见的任务。Perl作为一种强大的脚本语言，为开发人员提供了许多处理数据的功能和工具。在本文中，我们将学习如何使用Perl将哈希数据导出到Excel文件中。

perl
use strict;
use warnings;
use Spreadsheet::WriteExcel;
# 创建Excel文件
my $workbook = Spreadsheet::WriteExcel->new('students.xls');
my $worksheet = $workbook->add_worksheet();
# 定义标题行
my @headers = ('姓名', '年龄', '分数');
$worksheet->write_row(0, 0, \@headers);
# 定义学生数据
my %students = (
    'John' => { age => 18, score => 90 },
    'Alice' => { age => 17, score => 95 },
    'Bob' => { age => 19, score => 88 },
);
# 写入学生数据
my $row = 1;
foreach my $name (keys %students) {
    my $student = $students{$name};
    $worksheet->write($row, 0, $name);
    $worksheet->write($row, 1, $student->{age});
    $worksheet->write($row, 2, $student->{score});
    $row++;
}
# 关闭Excel文件
$workbook->close();

perl

    'Alice' => { age => 17, score => 95 },
    'Bob' => { age => 19, score => 88 },
);
# 写入学生数据

foreach my $name (keys %students) {
    my $student = $students{$name};
    $worksheet->write($row, 0, $name);
    $worksheet->write($row, 1, $student->{age});
    $worksheet->write($row, 2, $student->{score});
    $row++;
}
# 关闭Excel文件
$workbook->close();
