Hi, everybody!
With Spring this year comes not only warmer weather but also a totally new season of Just KNIME It! Don’t forget to register here to get updates every time a new challenge comes out.
If you have any suggestions for challenges, please let us know in this thread! 
In the past we had challenges that were co-developed with KNIME Forum users, and we definitely want it to be a tradition.
Stay tuned for more Just KNIME It! news, and thanks for all your support. 
Thanks for your suggestions, @Marthael!
Problems related to paginated API… Just solved this last week!
Download a dataset from FRED and perform a time series analysis.
Cool! Just wrote this one down as well.
Why not take some inspiration from the Excel World Championship?
It might also be an opportunity to show the advantages of Knime over “traditional” tools.
eInvoices will soon be mandatory in B2B transactions (January 2025). They are in XML format… that might be something?
Most challenges, at least of the recent past, were about “Take this data any visualize it”. Within each / most data set(s) I found issues like data not being explained well, being inconcise (single colon amongst numbers) numbers or numbers don’t add up:
Example
Sum of percentage of respective group exceeding 100
Understanding the data, making it usable, filtering it for statistical analysis, identifying outliers etc. relates to necessary skills we all must hone and keep sharp.
Why not creating a multi-step challenge where we must:
Challenge #1: Check an pre-process the data
Challenge #2: Transform the pre-processed data or enriching it with other sources
Challenge #3: Visualize it
During each iteration submitted contestants results would get evaluated and only those solutions that meet certain criteria would be allowed to pass on or better, would be considered for the finals to give everyone the opportunity to learn.
Almost like a ETL-Triathlon. There would be less challenges as the competition is more complex to organize but it would be much more entertaining, wouldn’t it?
Hi! We really like your ideas and appreciate your feedback! 
We have a few challenges down the road that partially address your suggestions, and we’ll consider creating new ones that cover more of what you mentioned.
Awesome to hear … “let’s get cracking”
