2023: Week 44 - Solution



Solution by Tom Prowse and you can download the workflow here.


Step 1 - Missing Dates

First we want to input the Events table and then utilise the New Rows steps to fill in the missing dates between the first day of term and last day of term.

The new rows step is setup with using the Date field between the min/max dates with an increment of 1 day:



After the new rows have been created we want to find the weekday for each of the dates so we can duplicate the date field and then convert the duplicate to day of week


Then we can filter to remove the weekend days (Saturday & Sunday). The table should now look like this: 




Step 2 - After School Clubs

Now we can include the After School Clubs data source and join with our existing workflow using the day of the week fields on both sides.



Finally we can replace the null values in the Event field with N/A by double clicking on the profile pane and typing 'N/A'.

Our final output looks like this:

How to...Handle Free Text

Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
