Alteryx - How to Use RegEx Tool and Formula Tool

In this tutorial, we will learn "How to Extract a Pattern from a String by RegEx tool" in Alteryx tool.

In this tutorial, we will learn "How to create derived columns by Formula tool" in Alteryx tool.

Alteryx has many tools which comes in data parsing category includes tools that prepare data parsing for downstream analysis and one of them is Regular Expression tool which uses regular expression syntax to parse, match, or replace data.

While regular expressions are supported in Designer, users are responsible for their own expressions and how the expressions impact their data. For more resources on how to write regular expressions, see www.regexlib.com, a site unaffiliated with Alteryx, or the RegEx Coach, a unaffiliated graphical application for Windows which can be used to experiment with (Perl-compatible) regular expressions interactively.

For additional information about Boost RegEx, see the following: Boost-Supported RegEx Character Classes Collating Element Names Boost-Extended Format String Syntax POXIS Extended Regular Expression Syntax

Alteryx has many tools which comes in data preparation category includes tools that prepare data for downstream analysis. and one of them is Formula tool which The Formula tool creates a new column, or updates a column, using one or more expressions to perform a variety of calculations and operations. See Functions for a list of functions to use when building an expression.

Use the Formula tool to: Apply conditional statements Convert numbers and strings Format dates Extract file paths Apply financial algorithms or mathematical calculations Find minimum and maximum values Analyze spatial data Cleanse string data Perform validation tests on data
