Hey,

thanks for the answer. That works, for one single line and for a right formated "timestamp". I think, my document has about 2000 lines, so how can I transfer your idea to my document? And another problem is the " timestamp. Firefox stores the last_visit_date-entry in a string which looks like this

Code:
1263818137802359

but the timestamp is only the first 10 characters of this sting

Code:
1263818137

I don't know what the other 6 characters are for, and that does not matter for me at the moment. So, I know that I can reduce the string to the first 10 characters with the substr command, for example

Code:
substr($1,1,10)

which will do exactly what I discribed. The Problem ist the csv, that you can see in the "Question-post" at the beginning of this thread. I export a sqlite-database to csv. This csv, hast 10 values, separated by ";" in each line. But I only need the second and 10th value of each line. The 10th value is this (somehow) strange timestamp, that must be reduced to the first ten characters and changed into a real date. After all I want to store the date followed by the visited URL in a new document that should look like this

Code:
"date" "URL"
"another date" "another URL"
...
...
...

How can I do this?SmilieSmilieSmilie

Text::CSV::Encoded::Coder::EncodeGuess(3pm)		User Contributed Perl Documentation	       Text::CSV::Encoded::Coder::EncodeGuess(3pm)

NAME
Text::CSV::Encoded::Coder::EncodeGuess - Text::CSV::Encoded coder class using Encode::Guess SYNOPSIS
use Text::CSV::Encoded coder_class => 'Text::CSV::Encoded::Coder::EncodeGuess'; use Spreadsheet::ParseExcel; my $csv = Text::CSV::Encoded->new(); $csv->encoding( ['ucs2', 'ascii'] ); # guessing ucs2 or ascii? $csv->encoding_to_combine('shiftjis'); my $excel = Spreadsheet::ParseExcel::Workbook->Parse( $file ); my $sheet = $excel->{Worksheet}->[0]; for my $row ( $sheet->{MinRow} .. $sheet->{MaxRow} ) { my @fields; for my $col ( $sheet->{MinCol} .. $sheet->{MaxCol} ) { my $cell = $sheet->{Cells}[$row][$col]; push @fields, $cell->{Val}; } $csv->combine( @fields ) or die; print $csv->string, " "; } DESCRIPTION
This module is inherited from Text::CSV::Encoded::Coder::Encode. USE
Except for 2 attributes, same as Text::CSV::Encoded::Coder::Encode. encoding_in $csv = $csv->encoding_in( $encoding_list_ref ); The accessor to an encoding for pre-parsing CSV strings. If no encoding is given, returns current $encoding, otherwise the object itself. $encoding_list_ref = $csv->encoding_in() When you pass a list reference, it might guess the encoding from the given list. $csv->encoding_in( ['shiftjis', 'euc-jp', 'iso-20022-jp'] ); If it cannot guess the encoding, the first encoding of the list is used. encoding $csv = $csv->encoding( $encoding_list_ref ); $encoding_list_ref = $csv->encoding(); You can pass a list reference to this attribute only: * For list data consumed by combine(). * For list reference returned by getline(). In other word, in "combine" and "print", it might guess an encoding for the passing list data. If it cannot guess the encoding, the first encoding of the list is used. SEE ALSO
