Magento export categories -> import with magmi - magento

Question

we need to change the categories of some products and it is easier for us to do this with a csv file.
Is there a way to export the categories in magmi format?
sku,categories
"abc","cat1/cat2;;cat5/cat6/cat1"
"bgb","cat1/cat2"
or is there maybe a small tool to manage the products in categories?
Edit:
this is the current code which is displaying the category names.
But I am trying to display the category path like this:
FirstCat/Tools/Screwdriver
But it is displaying like this:
FirstCat/Screwdriver/Tools
so the categoryid is not sorted.
<?php
error_reporting(E_ALL | E_STRICT);
define('MAGENTO_ROOT', getcwd());
$mageFilename = MAGENTO_ROOT . '/app/Mage.php';
require_once $mageFilename;
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
Mage::app();
$products = Mage::getModel("catalog/product")->getCollection();
$products->addAttributeToSelect('category_ids');
$products->addAttributeToSelect('sku');
$products->addAttributeToFilter('status', 1);//optional for only enabled products
$products->addAttributeToFilter('visibility', 4);//optional for products only visible in catalog and search
$fp = fopen('exports.csv', 'w');
$csvHeader = array("sku", "category_ids");
fputcsv( $fp, $csvHeader,",");
foreach ($products as $product){
$sku = $product->getSku();
$i = 2;
$len = count($product->getCategoryIds());
$str = "";
foreach ($product->getCategoryIds() as $id){
$category = Mage::getModel('catalog/category')->load($id);
$name = $category->getName();
$str .= $name;
if($i <= $len) {
$str = $str .= "/";
}
$i++;
}
fputcsv($fp, array($sku, $str), ",");
}
fclose($fp);

I use this code to export out categories. You can try to run it, don't forget to modify your path to your mage/app.php:
<?php
require_once('../yourpath/app/Mage.php');
Mage::app('admin');
Mage::app()->getStore()->setId(Mage_Core_Model_App::ADMIN_STORE_ID);
Mage::register("isSecureArea", true);
function saveData($file, $data) {
$fh = fopen($file, 'w');
foreach ($data as $dataRow) {
fputcsva($fh, $dataRow);
}
fclose($fh);
return $this;
}
function fputcsva(&$handle, $fields = array(), $delimiter = ',', $enclosure = '"') {
$str = '';
$escape_char = '\\';
foreach ($fields as $value) {
if (strpos($value, $delimiter) !== false ||
strpos($value, $enclosure) !== false ||
strpos($value, "\n") !== false ||
strpos($value, "\r") !== false ||
strpos($value, "\t") !== false ||
strpos($value, ' ') !== false) {
$str2 = $enclosure;
$escaped = 0;
$len = strlen($value);
for ($i = 0; $i < $len; $i++) {
if ($value[$i] == $escape_char) {
$escaped = 1;
} else if (!$escaped && $value[$i] == $enclosure) {
$str2 .= $enclosure;
} else {
$escaped = 0;
}
$str2 .= $value[$i];
}
$str2 .= $enclosure;
$str .= $str2 . $delimiter;
} else {
if (strlen($value)):
$str .= $enclosure . $value . $enclosure . $delimiter;
else:
$str .= $value . $delimiter;
endif;
}
}
$str = substr($str, 0, -1);
$str .= "\n";
return fwrite($handle, $str);
}
function geturl($connect, $value){
$id= $value;
if ($id) {
$sql = "SELECT value FROM magento.catalog_category_entity_url_key where entity_id=$id;";
$result = $connect->query($sql)->fetchObject();

In this solution the db was'n in very well state, so the url needs to grabbed separately, you can remove that part if not necessary for you.
I used this on EE 1.13.0.2
You can run it from the shell.

Now here is my solution. Its displaying the csv in the browser. After that you can reimport with magmi
<?php
error_reporting(E_ALL | E_STRICT);
define('MAGENTO_ROOT', getcwd());
$mageFilename = MAGENTO_ROOT . '/app/Mage.php';
require_once $mageFilename;
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
Mage::app();
$products = Mage::getModel("catalog/product")->getCollection();
$products->addAttributeToSelect('category_ids');
$products->addAttributeToSelect('sku');
$products->addAttributeToFilter('status', 1);//optional for only enabled products
$products->addAttributeToFilter('visibility', 4);//optional for products only visible in catalog and search
foreach ($products as $product){
$sku = $product->getSku();
echo $sku.",";
$i = 2;
$anzahl = count($product->getCategoryIds());
foreach ($product->getCategoryIds() as $id){
$category = Mage::getModel('catalog/category')->load($id);
$path = $category->getPath();
$ids = explode("/", $path);
$name = "";
$i2 = 2;
$anzahl2 = count($ids);
foreach($ids as $id_2) {
$category = Mage::getModel('catalog/category')->load($id_2);
$name .= $category->getName();
echo $category->getName();
if($i2 <= $anzahl2) {
$name .= "/";
echo "/";
}
$i2++;
}
if($i <= $anzahl) {
$name .= ";;";
echo ";;";
}
$i++;
}
echo "<br />";
}
