I want to update just the prices of all products in my Magento 2 store and to do this quickly and easily i have a CSV with sku and price and was hoping price could be updated using sku as an identifier.

Using the default magento import process however i am being asked for extra fields including product_type,attribute_set_code,name ect.

Is there a quick and easy way to do this with just sku and price as none of these other fields need modifying?

Here is the simple script that does the job for you (easiest & fastest approach):

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Capture warning / notice as exception
set_error_handler('ctv_exceptions_error_handler');
function ctv_exceptions_error_handler($severity, $message, $filename, $lineno) {
    if (error_reporting() == 0) {
        return;
    }
    if (error_reporting() & $severity) {
        throw new ErrorException($message, 0, $severity, $filename, $lineno);

  • This script prompts the following error (on localhost): "EXCEPTION::#0 C:\Server\htdocs\pub\update-prices.php(182): ctv_exceptions_error_handler(8, 'Undefined offse...', 'C:\\Server\\htdoc...', 182, Array) #1 {main}" – Iveta Allogenes Apr 11 at 15:49

The fastest method in my mind is:

  1. Export your products into CSV first, then just edit the column price to update the product price.

  2. Import the edited CSV into Magento, remember to choose Add/Update on Import Behaviour.

You can also simple write two column in csv that is sku and price and import them,that will update vary fast.

  • I can't seem to do this i am asked for additional fields, how do you get it to work with just these 2 fields? – harri Jun 23 '17 at 14:34
