How To Export and Import Category in Magento

For export category  create a simple php file catgory.php in root Folder.
<?php
    ini_set("memory_limit","1000M");
    require_once "app/Mage.php";
    umask(0);
    Mage::app();
    $category = Mage::getModel ( 'catalog/category' );
    $tree = $category->getTreeModel ();
    $tree->load();
    $ids = $tree->getCollection()->getAllIds();
    if ($ids) {
    $string='';
    $heading = '"store","categories","cat_id","is_active","meta_title","meta_keywords","meta_description","include_in_menu","is_anchor","description",';
    foreach ($ids as $id) {
    if($id>0)//start if removeroot category and default category .
    {

    $cate_cre = Mage::getModel('catalog/category');

    $cate_cre->load($id);
    $treeurl='';
    $cate_cre1=Mage::getModel('catalog/category')->load($id);
    $treeurl=$cate_cre->getName();
    if($cate_cre1->getParentId()>0)
    {
    for($i=0; ;$i++)
    {
    if($cate_cre1->getParentId()>0)
    {
    $abc=Mage::getModel('catalog/category')->load($cate_cre1->getParentId());
    $pCat=$abc->getName();
    if($abc->getId()>1){
    $treeurl=$pCat.'/'.$treeurl;
    }
    $cate_cre1=$abc;
    }
    else{
    break;
    }
    }
    }
    $store = "default";
    $string .='"'.$store.'","'.$treeurl.'","'.$id.'","'.$cate_cre->getIsActive().'","'.$cate_cre->getMetaTitle().'","'.$cate_cre->getMetaKeywords().'","'.$cate_cre->getMetaDescription().'","'.$cate_cre->getIncludeInMenu().'","'.$cate_cre->getIsAnchor().'","'.$cate_cre->getDescription().'"';
    $string.="\n";
    }//endof if removeroot category and default category .
    }
    $csv_output = $heading ."\n".$string;
    $filename = "Categories";
    header("Content-type: application/vnd.ms-excel");
    header("Content-disposition: csv" . date("Y-m-d") . ".csv");
    header( "Content-disposition: filename=".$filename.".csv");
    print $csv_output;
    }
    ?>

After run this file at browser .u got a csv file-

After the export category you must need to import the categories and  you want to import the categories with previous category structure.For that work i craeted a folder ImpCat folder at app\code\local\
first i craete  file at a file Category.php  at app\code\local\ImpCat\Catalog\Model\Convert\Adaptera\

<?php

    ?>

There for need  config.xml file for configuration placed  at app\code\local\ImpCat\Catalog\etc\ -

<?xml version="1.0"?>
    <config>
     <global>
     <models>
     <catalog>
     <rewrite>
     <convert_adapter_category>ImpCat_Catalog_Model_Convert_Adapter_Category</convert_adapter_category>
     </rewrite>
     </catalog>
     </models>
     </global>
    </config>









Now craete  module controller file ImpCat_All.xml at app\etc\modules-

<?xml version="1.0"?>
    <config>
     <modules>
     <ImpCat_Catalog>
     <codePool>local</codePool>
     <active>true</active>
     </ImpCat_Catalog>
     </modules>
    </config>






then, create a  dataflow advanced profile into -admin/system/Import Export/Dataflow Advanced Profile and give the Profile Name is 'category import'and
its Actions XML  is-





<action type="dataflow/convert_adapter_io" method="load">
     <var name="type">file</var>
     <var name="path">var/import</var>
     <var name="filename"><![CDATA[Categories.csv]]></var>
     <var name="format"><![CDATA[csv]]></var>
    </action>
    <action type="dataflow/convert_parser_csv" method="parse">
     <var name="delimiter"><![CDATA[,]]></var>
     <var name="enclose"><![CDATA["]]></var>
     <var name="fieldnames">true</var>
     <var name="store"><![CDATA[0]]></var>
     <var name="number_of_records">1</var>
     <var name="decimal_separator"><![CDATA[.]]></var>
     <var name="adapter">catalog/convert_adapter_category</var>
     <var name="method">parse</var>
    </action>



after create import categoryextension you goes to admin system->permission->roles->Administrators ->Role Users

click on Save Role.Then Flush magento Cache.
Then downloaded  Categories.csv put Categories.csv into var/import/
and removed cat_id colums from csv and
remove first two rows

and remove all Default Category/ from categories colunn in Categories.csv.
Now you go to again- admin/system/Import Export/Dataflow Advanced Profile  run 'category import' profile>Run Profile>click 'Run Profile in Popup' import of category now start and automatically created category. Now you fill happy.Click here to download
click for csv
