The following file provides syntax highlighting for the Impex syntax. For further information, check out the [SAP Commerce Cloud Help Site] (formerly known as SAP Hybris).
In order to install the Impex syntax highlighting, open up Sublime Text 3 and go to Preferences > Browse Packages... . This will open a directory containing a User subdirectory.
Simply copy & paste the impex folder from this repository into the User directory. The changes are available immediately. Whenever you open a file with an *.impex or .csv extension, highlighting should now be available.
