If you need to migrate your blog from Wordpress to Jekyll there is a PHP code for it.

Wordpress to Jekyll

<?php
    // This is the script I used to export my old blog out of WordPress and into a
	// Jekyll friendly format. The first half exports posts, the second does pages.
	// It's fairly specific to my needs, but maybe it'll be a good starting point
	// for you. /RTH 2011-08-28

	date_default_timezone_set('America/Los_Angeles');

    $db = mysql_connect('host', 'username', 'pass')  or die(mysql_error());
    $d = mysql_select_db('dbname', $db)  or die(mysql_error());

	// Export posts...
    $posts = array();
    $results = mysql_query("select * from wp_posts where post_type = 'post' and post_status = 'publish'")  or die(mysql_error());
    while($row = mysql_fetch_array($results, MYSQL_ASSOC))
	{
		$results2 = mysql_query("select meta_key, meta_value FROM wp_postmeta where post_id = " . $row['ID'], $db) or die(mysql_error());
		while($row2 = mysql_fetch_array($results2, MYSQL_ASSOC))
		{
			$row[$row2['meta_key']] = $row2['meta_value'];
		}
        $posts[] = $row;
	}

	mkdir('posts', 775);

    foreach($posts as $p)
    {
        $slug = $p['post_name'];
        $dt   = $p['post_date_gmt'];
		$y    = date('Y', strtotime($dt));
		$m    = date('m', strtotime($dt));

		$out  = "---\n";
		$out .= "date: $dt\n";
