I have created a custom report,

Used below code in my ui_component listing file.

<column name="custom_tax_code" class="Vendor\Module\Ui\Component\Listing\Column\Quantity">
 <argument name="data" xsi:type="array">
  <item name="config" xsi:type="array">
  <item name="filter" xsi:type="string">false</item>
  <item name="label" xsi:type="string" translate="true">Tax Code</item>

<column name="shipping_amount_custom" class="Vendor\Module\Ui\Component\Listing\Column\Quantity" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="filter" xsi:type="string">false</item>
                <item name="label" xsi:type="string" translate="true">Shipping Amount</item>

Then in Quantity.php

 class Quantity extends \Magento\Ui\Component\Listing\Columns\Column {

  public function prepareDataSource(array $dataSource) {
    if (isset($dataSource['data']['items'])) {       
     foreach ($dataSource['data']['items'] as & $item) {

     $item['custom_tax_code'] = $taxcode; // used some logic to get this value
     $item['shipping_amount_custom'] = $lastItemShippingAmt;// used some logic to get this value
   return $dataSource;

This code is working fine and it is showing properly in admin Grid, But when exported to CSV, values for these 2 columns are not showing. likewise i have many other custom columns. posted only 2 here.

How to resolve this issue? Can anyone help me out please. Thanks


Magento doesn't render the custom fields on export.


You should add some specific customization for export. I suppose in case dynamic values you can add plugins for these methods:



P.S. Otherwise you can try to add your needed data to collection directly, using custom attributes or join to needed table(s), so that the code $document->getCustomAttribute($column)->getValue() retrieve the correct value.

Here we can see how was solved the similar issue with empty fields in the exported CSV for customer grid -

  • @jafar pinjar If you want a working solution, you need to provide your extension code entirely. – sergei.sss Oct 17 '19 at 10:36
  • hi @sergei, can you pls share your email id? – jafar pinjar Oct 17 '19 at 11:23
  • You can temporary upload your code to github, it will be more convenient for me to change it. And more people will be able to help you. – sergei.sss Oct 17 '19 at 11:36

I crate a Admin Grid using Ui-Component.

You want all Data you have create a Custom Export Button that export your all data.

edit in your Ui-Component file where Admin Grid Show

[vendor_name] \ [module_name] \view\adminhtml\ui_component

Add this code to add Button into Admin Grid


<item name="buttons" xsi:type="array">

    <item name="import" xsi:type="array">
        <item name="name" xsi:type="string">import</item>
        <item name="label" xsi:type="string" translate="true">Import</item>
        <item name="class" xsi:type="string">secondary</item>
        <item name="url" xsi:type="string">*/*/importdata</item>
        <item name="sortOrder" xsi:type="number">20</item>

    <item name="export" xsi:type="array">
        <item name="name" xsi:type="string">export</item>
        <item name="label" xsi:type="string" translate="true">Export</item>
        <item name="class" xsi:type="string">secondary</item>
        <item name="url" xsi:type="string">*/*/exportdata</item>
        <item name="sortOrder" xsi:type="number">30</item>


Now create a File that Export or Import Data. File Name must be same as you define in Ui-Component file

  <item name="url" xsi:type="string">*/*/exportdata</item>

  <item name="url" xsi:type="string">*/*/importdata</item>

File path must be like this

[vendor_name] \ [module_name] \ Controller \ Adminhtml \ [Controller_name] \ Exportdata.php



namespace [vendor_name]\[module_name]\Controller\Adminhtml\[Controller_name];

use Magento\Framework\App\Filesystem\DirectoryList;

class Exportdata extends \Magento\Backend\App\Action
    protected $uploaderFactory;

    protected $_locationFactory; 

    public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \Magento\Framework\App\Response\Http\FileFactory $fileFactory,
        \Magento\Framework\Filesystem $filesystem,
        \[vendor_name]\[module_name]\Model\locatorFactory $locationFactory // This is returns Collaction of Data

    ) {
       $this->_fileFactory = $fileFactory;
       $this->_locationFactory = $locationFactory;
       $this->directory = $filesystem->getDirectoryWrite(DirectoryList::VAR_DIR); // VAR Directory Path

    public function execute()
        $name = date('m-d-Y-H-i-s');
        $filepath = 'export/export-data-' .$name. '.csv'; // at Directory path Create a Folder Export and FIle

        $stream = $this->directory->openFile($filepath, 'w+');

        //column name dispay in your CSV 

        $columns = ['Col-1-name','Col-2-name','Col-3-name','Col-4-name','Col-5-name','Col-6-name','Col-7-name','Col-8-name','Col-9-name',];

            foreach ($columns as $column) 
                $header[] = $column; //storecolumn in Header array


        $location = $this->_locationFactory->create();
        $location_collection = $location->getCollection(); // get Collection of Table data 

        foreach($location_collection as $item){

            $itemData = [];

            // column name must same as in your Database Table 

            $itemData[] = $item->getData('col-1-name');
            $itemData[] = $item->getData('col-2-name');
            $itemData[] = $item->getData('col-3-name');
            $itemData[] = $item->getData('col-4-name');
            $itemData[] = $item->getData('col-5-name');
            $itemData[] = $item->getData('col-6-name');
            $itemData[] = $item->getData('col-7-name');
            $itemData[] = $item->getData('col-8-name');
            $itemData[] = $item->getData('col-9-name');



        $content = [];
        $content['type'] = 'filename'; // must keep filename
        $content['value'] = $filepath;
        $content['rm'] = '1'; //remove csv from var folder

        $csvfilename = 'locator-import-'.$name.'.csv';
        return $this->_fileFactory->create($csvfilename, $content, DirectoryList::VAR_DIR);



Now you can Click on the Export Button and See your .csv file Downloaded below.

I Hope This Helps You.
