Sometimes we want the front end of our blog to be translated for the users, but keep the backend admin panel in English. Admin in English with Switch does just that. It lets you switch your backend administration panel to English from admin toolbar, even if the rest of your blog is translated into another language. This plugin allows turning English language on and off for each user’s back-end independently.

Lets you override default texts from your admin panel. 
Originally built to override texts from Woocommerce, but also works for all neatly added texts by WordPress Core and plugins. 
 
It will translate all _e(”) or __(”) string calls, so check the PHP sourcecode of the plugin or theme you need to translate. 
 
It will NOT translate any dynamic strings like %s or %d, so “%s has been added to your cart.” is not translatable. 
 
It will NOT translate any strings that contain HTML tags at all. 
 
Some WooCommerce examples: 
WooCommerce “Select option” (dropdown value) setting
