# Use RegEx to find text strings

A regular expression (also known as RegEx or RegExp) is a text string that describes a text search pattern. RegEx helps refine data and collects only what you need. RegEx can be used in Mozenda to define how a Capture Text action parses (or analyzes) the text it is targeting. 

Use the RegEx tool to:
* Identify patterns
* Change the display format
* Remove excess data among other things such as:
* Separate the city, zip, state, and street address from a full address
* Remove the currency sign from the price
* Refine the captured text
* Ensure that all captured data fits the required format
