The Filter Tool, which is part of the Preparation tool category, separates your data into 2 output streams, True and False, based on a basic filter or custom expression.
The Multi-Row Formula Tool functions much like the normal Formula Tool but adds the ability to reference multiple rows of data within one expression. Say, for example, someone was on the ground floor of a house and had a Formula Tool. They would only be able to talk to the people also on the ground floor. If they had a Multi-Row Formula Tool, though, they would also be able to talk to the people upstairs, in the attic, and in the basement as well.
Data blending, transformation and cleansing..oh my! Whether you're looking to apply a mathematical formula to your numeric data, perform string operations on your text fields (like removing unwanted characters), or aggregate your spatial data (among many other things!), the Formula Tool is the place to start. With the examples provided below, you should be on your way to harnessing the many functions of the Formula Tool:
The Dynamic Replace Tool is an under-utilized tool in the Developer Toolset that is very powerful. It allows for dynamic formulas or conditions to be used in your workflow. It was first introduced in Alteryx 6.1. It’s one of the few tools that is currently multi-threaded which makes is fast.
The RegEx tool is kind of like the Swiss Army Knife of parsing in Alteryx; there are a whole lot of ways you can use it to do things faster or more effectively, but even if you just use the blade it's still immensely useful. Sometimes that's all you need, but if you do take the time to figure out how to use a few other tools in that knife, you'll start to see that there isn't much you can't do with it.
A must-have for any app or macro, the Error Message Tool displays a prompt to the user based on input from Interface Tools. Using any expression that evaluates to true, along with any number of user inputs from question anchor connected Interface Tools, the Error Message Tool can layer even the most involved applications with failsafes that ease a user’s experience through more robust interactions.
