Question

It is no longer possible to export your Facebook friends to Twitter or Google+ in the way it once was by using Yahoo mail- http://lifehacker.com/5824769/how-to-migrate-all-your-facebook-data-to-google%252B
Yahoo now (presumably forced by Facebook) tag all imported Facebook friends so you can’t then export them.
I am wanting to find a way of converting Yahoo contacts to a CSV file including Facebook contacts, and thought the best way would be converting the simple print view (see https://dl.dropbox.com/u/95261/CloudShot/shot_21062012_153052.png ) to a CSV file.

Ideally I’d use a Bookmarklet and thought I could use a plugin similar to Table2CSV-
http://www.kunalbabre.com/projects/table2CSV.php

I created the following bookmarklet as a test:

javascript:;var s=document.createElement('script'); s.setAttribute('src','http://jquery.com/src/jquery-latest.js'); document.getElementsByTagName('body')[0].appendChild(s); s.setAttribute('type', 'text/javascript'); var t=document.createElement('script'); t.setAttribute('src','http://www.kunalbabre.com/projects/table2CSV.js'); document.getElementsByTagName('body')[0].appendChild(t); t.setAttribute('type', 'text/javascript'); $('qprintable').table2CSV();

This doesn’t work because the table in Yahoo print contacts puts each contact in a separate table. I’ve got a sample here (I’ve changed the details to protect the privacy!)- http://pastebin.com/STuKmwQa

Ideally I’d be able to either download as a CSV or copy and paste. I’d like to use a bookmarklet as I want this to be easy for the end user and hope this will benefit all the people that currently can’t export their Facebook contacts easily.

How do I achieve this?

http://jsfiddle.net/GMmdg/5/

general selector format:

xtract('table.container-of-inner-tables table.child-tables');

concrete selector for jsfiddle, but it probably won’t work with actual page:

xtract('body > table > tbody > tr:not(.qprintfoot) table');

Data extractor function, change internal selectors if necessary:

function xtract( rootTableSelector ){
    var rows = [];
    var csv = [];
    $( rootTableSelector ).each(function(){
        var $t = $(this);
        var row = {};
        row.name  = $.trim( $t.find('tr:nth-child(1) > td > b').text());
        row.email = $.trim( $t.find('tr:nth-child(2) > td > div:nth-child(2)').text());
        rows.push( row );
        csv.push([ row.name, row.email ]);
    });
    console.log( rows );
    $('#result').text( toCSV( csv ) );
    $('#json').text( JSON.stringify( rows) );
    // prompt('this is not csv', csv );
}

Untested, freshly written function to create csv, enjoy the options:

function toCSV( rows ){
    var newline = '\n';
    var fsep = ','; // field separator
    var quot = '"'; // field quoter
    var quotquot = [ quot + quot, '\\' + quot ][1]; // choose
    var alwaysQuote = false;
    var quoteIfContainsQuote = true;
    // omitted option possibilities:
    // - trimFields
    // - quoteStringsButNotNumbers(excel)
    // - putEqualSignBeforeNumbers(excel), etc.

    var lines = [];
    $.each( rows, function(){
      var line = [];
      $.each( this, function(){
          var s = this;
          var needsQuote = alwaysQuote;

          if( s.indexOf( fsep ) >= 0 )
              needsQuote = true;

          if( s.indexOf( quot ) >= 0 ){
              needsQuote = needsQuote || quoteIfContainsQuote;
              s = s.replace( quot, quotquot );
          }

          if( needsQuote ) s = quot + s + quot;
          line.push( s );
      });
      lines.push( line.join( fsep ));
    });
    return lines.join( newline );
}
