Wakeupdata's expression engine is the tool that will empower professionals like you to optimize and clean your product data in more than 100 ways - probably the most flexible tool that is available on the market. 

By using the expression engine, you are able to make changes in bulk which will save you valuable time and ensure that your product data feed is always going to be consistent across all products.

How does it work?

Simply put, the expression engine is a set of pre-defined commands that once you master, will help you structure data in virtually any way possible. For example, you will be able to remove text, create more complete product titles by combining attributes (i.e. brand + title), replace values, perform calculations and much more.

In more technical terms, the expression engine is a set of regular expressions (regex). If you are already familiar with the regex language, then you will find this tool extremely simple and straightforward.
