In Magento, you can change the language of the admin panel to better suit the needs of your users. Here are the steps to change the admin panel language in Magento:
Log into the Magento admin panel.
Go to System > Configuration > General > Locale Options.
In the “Locale” dropdown menu, select the language you want to use for the admin panel.
Click on the “Save Config” button.
Log out and log back into the Magento admin panel to see the changes take effect.
Note: If you’re using Magento 2, you should check the documentation for more details on how to change the admin panel language.
Also, If the language you want to use is not available in the dropdown menu, you can install a language pack by going to System > Configuration > General > Locale Options > Locale and choosing the option “Add language” and then selecting the language you want.
