This article is part of the Tool Mastery Series, a compilation of Knowledge Base contributions to introduce diverse working examples for Designer Tools. Here we’ll introduce App and Macro resources for mastering the Alteryx Designer:
Fact: workflows are the best. Look it up. They’re all about getting things done and, with hundreds of tools and the ability to integrate external processes, there’s no shortage of things you can get done. We know that there are some areas of analytics that require a little extra firepower, however, and that’s why you can leverage your workflows in apps and macros for added functionality.
In short, an analytical application is simply a workflow that requires user input. For example, you may have a workflow that captures your analyses and outputs a report. Depending on who runs the report there may only be a few tables/data points of interest to that person, and you want to customize the output to that user, like the below:
To capture that user input you’d use the interface toolset and the input (the user’s name) would update a filter and header/text element in the workflow to generate an entirely different, customized, report upon run. You can learn how to build an analytical app here, by checking out the example case above (attached as Example Reporting App.yxwz), or by walking through the detailed samples in your Designer by navigating to Help > Sample Workflows > Use Scripting and Automation Tools > Build an App.
In addition to all the features that the underlying workflows lend to your apps, you can create custom errors and use the debug workflow tool in your interface designer to troubleshoot your app configurations. Our public Gallery also has a wealth of completed apps that could be useful or at least start a solid foundation when building your own. Just log in, hit next to your app of choice, and right click > edit the .yxwz file to open it in the Designer rather than as an interface. If you’re looking to share one of your masterpiece apps the gallery, we have App Building Guidelines that should also help.
Macros, on the other hand, are modules that have the flexibility to be run as a single tool within another module – often encapsulating a repeatable process. Similarly to apps, you can build some standard macros (learn how to build one here) by simply removing your input and output from your workflow and replacing them with the macro input and macro output interface tools, respectively. This will effectively let you “insert” the processing of that workflow into another by right clicking on your Designer canvas, selecting “Insert”, and choosing your macro from the file browser that opens after selecting the “Macro…” list option. Once your connections are established, your standard macro essentially just takes your input data stream and sends it through that encapsulated workflow before returning the output to continue downstream.
To add to the arsenal, you can also build batch and iterative macros. Batch macros (learn how to build one here) will also execute whatever repeatable process is nested by the macro, but it will rerun and reconfigure for each control parameter – often grouping “packets” of input records by the control parameter to be used for their respective processing. Iterative macros (learn how to build one here, here or here) will make use of two macro outputs (one iterative output and one standard output with a termination condition) to rerun the enveloped workflow until either your maximum iterations are reached or all your records have iterated to satisfying the termination condition and have exited the standard output. All macros can make use of other interface tools to map fields or configure parameters as well, but they aren’t required.
Macros are extremely versatile because of their sheer customizability, and the best approach to learning how and when to use them, as well as how to build them to best suit your needs, is to absorb all the examples you can. Luckily, there’s a handful of detailed macro builds available in your Help > Sample Workflows > Use Scripting and Automation Tools > Build a Macro:
Just download and install macros to start using them to instantly bring that extra firepower into your analyses. After reviewing the above, you should also have a good idea on how to adapt them to better suit your workflows and how to apply similar techniques to build out Designer functionality of your own!
