I found a free Magento 2 extension from BSS Commerce which helped me work around this:

It provides some override code for the Model\Export\Product core class which breaks out the additional_attributes field into separate columns. In my testing it works on Import and Export.

You do have to configure an Admin setting for the module to tell it which fields to break out into their own columns, but it was easy to set up.

This module saved me some time duplicating their efforts, which was nice, and now the client can provide a normal CSV with attributes in columns, without me having to transform it with a script :)


Solution :

For this Need to do some changes in vendor\magento\module-catalog-import-export\Model\Export\Product.php file or override same model file in your custom module .

In vendor\magento\module-catalog-import-export\Model\Export\Product.php file add custom_attributes code those you want in separate cell ( not in additional_attributes cell) in $_exportMainAttrCodes global array variable line no. 263.

For example :

if suppose your export csv file contained

"collection_year=2014,lining_color=Light,material=Cotton|Wool|Polyester,season=Winter" value under additional_attributes header field for particular product. so add collection_year, hanger, lining_color & material keys in this $_exportMainAttrCodes array variable like:

protected $_exportMainAttrCodes = [
   .......SO on

  • Yeah but this is just the export when you import the CSV again it won't update those attributes

  • @StevieG Do you find any solution for import? May 15, 2017 at 5:25
  • @GauravAgrawal I was forced to write a script to combine those custom attributes back into the additional_attributes column in the correct format and stripping out special characters

All custom attributes get appeared under "additional_attributes" header in the export separated by a comma (,). I am using Magento 2.0.7. enter image description here

To make these attributes occupy a separate cell, we can add more columns to the CSV.

  • I also tried the same and my custom attributes are getting exported under additional_attributes column. Try to find out in csv using search if your attribute is there in any column

  • Yes ! As you can see in the attached screenshot, number_of_colours , wash_instructions , are our custom attributes. I guess this time Magento2 chose to list all attributes under one roof inside the csv.

  • please review my comments already I point out it is come under additional attribute. RJ07, Kumar sorry guys it is my fault. I updated my question please review. Aug 3, 2016 at 9:05
  • @KumarA. where is the answer and where you share link for reference ? May 16, 2019 at 5:43

This formula works in Excel, assuming no values have commas.

=IFERROR(LEFT(RIGHT(H5, SUM(LEN(H5)-FIND("material=", H5)- LEN("material="), 1)), IFERROR(FIND(",", RIGHT(H5, SUM(LEN(H5)-FIND("material=", H5)- LEN("material="), 1)))-1, LEN(RIGHT(H5, SUM(LEN(H5)-FIND("material=", H5)- LEN("material="), 1))))), "")

Just replace H5 and "material" with the appropriate cell and key.
