Learning a new tool can be daunting, especially if you are starting from square one with little to no experience. That’s why I’ve outlined a small list of free learning resources and exercises for a beginner with no experience to transition into a more intermediate...
We have all seen this problem in data transformation: names automatically becoming CAPITALISED NAMES or all lowercase names. If we have a list of cities consisting of only one word, it is quite straightforward to capitalise the first one using the following code: UPPER(left([Data],1)) + LOWER(right([data],LEN([data])-1)) However,...

Data is rarely perfect, and we know preparation matters – badly prepared data risks being slow or inaccurate. In an ideal world, we’d build our data prep into the data source or in something like Tableau Prep, providing a consistent (and likely faster) data source...
Running multiple flows every day from your computer and opening them one by one is a method that’s far from perfect. The reason why we put work into implementing more robust solutions than copy-paste between Excel workbooks was to cut the time on manual, repetitive...
Devs on Stage is probably my favorite keynote every Tableau Conference. With the move to virtual, it was reimagined to be Devs at Desks. We were invited into these developer and product manager homes to see what they have been working on for the future...

Geocoding addresses in a scalable and sustainable way has always been surprisingly difficult in the BI world, let alone in Tableau. You either need expensive datasets/services, overkill GIS tools, or you must rely on very legally dubious usage of seemingly free (but not really free)...
Tableau Prep has improved considerably since it was launched. It offers a lot of tools to pre-process and transform your data. But sometimes, you need to apply a function that has no equivalent in Prep, want to extract some data using an API interface or...
