如何为 A 的每一列生成 excel 格式的输出文件，即分别使用 perl 代码的 App 和 Data 的输出文件

Question

这是excel格式的输入文件：

A	B	C	D
APP	1	210101	8.1
APP	2	210102	8.2
APP	3	210103	8.3
Data	4	210104	8.4
Data	5	210105	8.5
Data	6	210106	8.6

如何使用 Perl 以下面的方式生成 excel 的输出文件？

输出文件 1（仅包含来自应用行的数据）：

A	B	C
1	210101	8.1
2	210102	8.2
3	210103	8.3

输出文件 2（仅包含来自数据行的数据）：

A	B	C
4	210104	8.4
5	210105	8.5
6	210106	8.6

Answer 1

下面是一个示例，说明如何根据输入文件第 0 列中的值将输入文件拆分为多个输出文件：

package Main;
use v5.22.0;         # experimental signatures requires perl >= 5.22
use feature qw(say);
use strict;
use warnings;
use experimental qw(signatures);
use Spreadsheet::ParseXLSX;
use Excel::CloneXLSX::Format qw(translate_xlsx_format);
use Excel::Writer::XLSX;

{
    my $self = Main->new(
        input_file    => 'input.xlsx',
        output_prefix => 'out',
    );
    my $worksheet = $self->scan_input_file();
    $self->open_output_files();
    my ( $row_min, $row_max ) = $worksheet->row_range();
    my $col0 = 0; # column number that contains the save type
    my @cols_to_save = (1..3);
    for my $row ( $row_min .. $row_max ) {
        my $cell = $worksheet->get_cell( $row, $col0 );
        my $save_type = $cell->unformatted();
        my $row = $self->get_row($worksheet, $row, \@cols_to_save);
        $self->save_row( $save_type, $row);
    }
    $self->close_output_files();
    say "Done.";
}


sub close_output_files( $self  ) {
    for my $file (keys %{$self->{files}}) {
        my $workbook = $self->{files}{$file}{workbook};
        $workbook->close();
    }
}

sub save_row( $self, $save_type, $cells ) {
    my $file = $self->{save_types}{$save_type};
    my $workbook = $self->{files}{$file}{workbook};
    my $worksheet = $self->{files}{$file}{worksheet};
    my $row = $self->{files}{$file}{row};
    my $col = 0;
    for my $cell (@$cells) {
        my $fmt = $cell->get_format();
        my $fmt_props  = translate_xlsx_format( $fmt );
        my $new_format = $workbook->add_format(%$fmt_props);
        my $value = $cell->unformatted() || '';
        $worksheet->write($row, $col, $value, $new_format);
        $col++;
    }
    $self->{files}{$file}{row}++;
}

sub get_row( $self, $worksheet, $row, $cols_to_save ) {
    my @row;
    for my $col (@$cols_to_save) {
        my $cell = $worksheet->get_cell( $row, $col );
        push @row, $cell;
    }
    return \@row;
}

sub new( $class, %args ) { bless \%args, $class }

sub scan_input_file( $self ) {
    my $parser = Spreadsheet::ParseXLSX->new;
    my $workbook = $parser->parse($self->{input_file});
    my $worksheet = $workbook->worksheet(0);
    my ( $row_min, $row_max ) = $worksheet->row_range();

    my %save_types;
    for my $row ( $row_min .. $row_max ) {
        my $col0 = 0;
        my $cell0 = $worksheet->get_cell( $row, $col0 );
        my $save_type = $cell0->unformatted();
        $save_types{$save_type} = 1;
    }
    $self->{save_types} = \%save_types;
    return $worksheet;
}

sub open_output_files( $self  ) {
    my $save_types = $self->{save_types};
    my $prefix = $self->{output_prefix};
    my %file_info;
    for my $type (keys %$save_types) {
        my $fn = $prefix . "_" . $type . '.xlsx';
        $save_types->{$type} = $fn;
        my $workbook = Excel::Writer::XLSX->new( $fn );
        my $worksheet = $workbook->add_worksheet();
        $file_info{$fn} = {
            workbook  => $workbook,
            worksheet => $worksheet,
            row       => 0,  # current row number
        };
    }
    $self->{files} = \%file_info;
}
