最近接触一些需要csv,txt,excel文件之间的转换,根据一些网上搜索加上自己的改动,实现自己想要的结果为主要目的,代码的出处已经找不到了,还请见谅,以下主要是针对csv&excel 和txt&excel写的perl脚本。
主要用到的模块是:
Text::CSV Spreadsheet::WriteExcel
Spreadsheet::ParseExcel
Spreadsheet::ParseExcel::FmtUnicode
Unicode::Map
|
可以支持中文,具体也没有要仔细说明的,直接看代码熟悉以上的模块吧!
execl2txt:
#!/usr/bin/perl #=============================================================================== # # FILE: excel2txt.pl # # USAGE: ./excel2txt.pl excel_filename txt_filename # # DESCRIPTION: Convert a Excel document to a text file # #===============================================================================
use strict; use warnings;
use Spreadsheet::ParseExcel; use Spreadsheet::ParseExcel::FmtUnicode;
unless($ARGV[0] && $ARGV[1]) { die "Please enter the filename of Excel document. Usage : excel2txt.pl [Excel filename] [Text filename] For example : excel2txt.pl input.xls output.txt"; }
# Chinese support
my $code = "CP936"; my $oFmtJ = Spreadsheet::ParseExcel::FmtUnicode->new(Unicode_Map => $code);
my $oExcel = new Spreadsheet::ParseExcel; my $doc = $oExcel->Parse($ARGV[0],$oFmtJ) or die "File open error:$!
"; my $outfile = $ARGV[1];
my $worksheet = $doc->{Worksheet}[0]; my $text;
# Get the excel data
for(my $row_num = $worksheet->{MinRow};$row_num <= $worksheet->{MaxRow};$row_num++) { for(my $col_num = $worksheet->{MinCol};$col_num <= $worksheet->{MaxCol};$col_num++) { $text .= $worksheet->{Cells}[$row_num][$col_num]?$worksheet->{Cells}[$row_num][$col_num]->Value:"";
if($col_num != $worksheet->{MaxCol}) { $text .= " "; # print tab
} else { $text .= "
"; # print <CR>
} } }
# Write to file
open FH,">$outfile"; print FH $text; close FH; print "done!
";

txt2excel: #!/usr/bin/perl #=============================================================================== # # FILE: txt2excel.pl # # USAGE: ./txt2excel.pl [txt filename] [excel filename] # # DESCRIPTION: Convert text file to excel #===============================================================================
use strict; use warnings;
use Unicode::Map; use Spreadsheet::WriteExcel;
unless($ARGV[0] && $ARGV[1]) { die " USAGE: ./txt2excel.pl [txt filename] [excel filename]
"; }
my $filename = $ARGV[1]; my $tmp_filename = $ARGV[0];
my $workbook = Spreadsheet::WriteExcel->new($filename); my $worksheet = $workbook->add_worksheet();
# Chinese support
my $Map = new Unicode::Map("GB2312");
# Convert word to unicode
sub w2u { my $word = shift; return $Map->to_unicode($word); }
my $row = 0; my $col = 0;
open FH,$tmp_filename or die"file open error.
"; while(<FH>) { chomp; $col = 0; s/s+//g; my @array = split(";",$_); foreach my $value (@array) { $worksheet->write_unicode($row,$col,w2u($value)); $col++; } $row++; } close FH; print "done!";

接下来看看csv&excel之间的转换:
#!/usr/bin/perl -W # # File: excel2csv.pl # License: GPL-2
use strict; use warnings;
use Spreadsheet::ParseExcel; use Spreadsheet::ParseExcel::FmtUnicode;
my $local_enc = "CP936";
unless($ARGV[0] && $ARGV[1]) { die "Please enter the filename of Excel document. Usage : excel2csv.pl [Excel filename] [Csv filename] For example : excel2csv.pl input.xls output.csv
"; }
my $oFmtJ = Spreadsheet::ParseExcel::FmtUnicode->new(Unicode_Map => $local_enc); my $excel = Spreadsheet::ParseExcel->new(); my $book = $excel->Parse($ARGV[0], $oFmtJ);
my $last_sheet = $book->{SheetCount} - 1;
my $filename = $ARGV[1]; open my $fh, ">", $filename or die "Can open $filename to write: $!
"; for my $worksheet ( @{ $book->{Worksheet} }[ 0 .. $last_sheet ] ) {
next if not defined $worksheet->{MaxRow} or not defined $worksheet->{MaxCol};
my @row = $worksheet->{MinRow} .. $worksheet->{MaxRow}; my @col = $worksheet->{MinCol} .. $worksheet->{MaxCol};
for my $row ( @{ $worksheet->{Cells} }[ @row ] ) { my @cellvalue = map { $_ = $_->Value() if ref $_; $_ = '' if not defined $_; $_; } @$row[ @col ]; print $fh join(";", @cellvalue), "
";
} } close $fh;
|
csv2excel用到的比较少,也就粗略了
#!/usr/bin/perl -w
use strict; use Text::CSV; use Spreadsheet::WriteExcel;
die("Usage: $0 [input filename(s)]
") if (scalar @ARGV == 0);
my $xl = Spreadsheet::WriteExcel->new('output.xls');
foreach my $filename (@ARGV) { my $csv = Text::CSV->new;
my $wsname = $filename; $wsname =~ s/.csv//g; $wsname =~ s/-/ /g; my $ws = $xl->add_worksheet($wsname);
my $row = 1; open FH, $filename; while (<FH>) { $csv->parse($_); my @fields = $csv->fields; $ws->write("A$row", @fields); $row++; }; close FH; }

主要是做为备份,以免忘记丢失。
