how did we transfer this data without errors?
Good video, it's so nice that you used the dataset of this platform.
How do you get the "changes" and the revision history to show on your tableau, mine only shows the table details, I'm on Tableau Professional Edition 2024.1.4
I had to create a calculated field by using an IF statement to change the flow card field to Yes / No values instead of 1 / 0. If I had the changes view, it would make it a lot easier.
I also couldn't do the "Keep Only" step for the flow cards because I don't have the step history on my Tableau
@@baller23killer are you using Tableau Prep Builder? Or are you trying to do the changes in Tableau Desktop? This video should help you see how to see the changes pane in Tableau Prep Builder: th-cam.com/video/VIyxvxNtqOI/w-d-xo.html
@@PreppinData I've only been using Tableau Desktop. I was unaware of Prep Building, thank you for linking this series, I will be giving the series a thorough watch to learn about Prep Builder!
Tableau Prep is such a game changer
It's a good video, so more videos like this one with daily life examples at Tableau Prep Builder. if you share data sets or files much better please.
how can do this in excel.
Enjoyed! Thanks for the Group trick 😊
Glad you enjoyed it
My god, it is so beautiful, thank you for sharing this quick, nice, and easy way of manipulating the data prep.
Glad it was helpful!
"Expression '[DONTSHOW-JOIN-15f054d6-b9aa-4ee8-8cfd-c67b2c3980a6] == 1' has one or more errors" I am getting this error after joining tables.
First I thought the hidden 'Rank' field wouldn't show up in the output. Wouldn't that be cool though?
Also, when I union at 2:32, I'm getting 7 Mismatched fields instead of just SortOrder. Why?
The union is based on the field names matching exactly.
Dunno if it's me but I keep getting a stupid error, "System error: An error occurred while communicating with data source 'LoomDataSource'" when changing Stage names.
That sounds like it's potentially a bug. What version of Tableau Prep are you using?
You forgot to mention that you also grouped [Location] in 3:47
I'm getting completely different results than yours. I think it could be because the data source has been updated or something. I done everything in this video step-by-step and my results are still showing different answers.
What a great challenge! You did a wonderful job explaining the lookup function, [Sign] and [Trend]. Thank you!
What a great challenge! Thank you for sharing the solution video.
Can you please show us how to do this in Excel? The date format will not change at ALL! I tried to change the format of the cell to a date format and even used the text-to-column to change it to date as well and they just don't respond to any changes. Very annoying and I would LOVE some help to do this. I was able to figure everything else out. Thank you!
One solution is go to POWER BI > Transform Data > Right click the column title > Click: Using Locale > Change data type to Date/Time > Change locale to English(United Kingdom) then copy your column in power BI then paste to your excel. That will solve it 100% and will save you a lot of time formulating excel functions.
Just use this formula - =TEXT(DATE(MID(E2,7,4),MID(E2,4,2),LEFT(E2,2)),"ddd") NOTE - E2 is the cell where the date is present. This will convert the string date to a date and then extract the day of the week from it
Thank you so much, really appreciate
I decided to use a branch for each subject with two joins after because I was getting null in the pivot step. The aggregate step following the pivot was crucial to the solution. The video is super helpful, thank you!
Ah! Unpivot is what I needed to do. And the unpivot needs to be done after removing [Grade], otherwise you'll get bunch of nulls.
Awesome video, so could you share the files to replicate the example, I think so we can understand better if you don't mind, I'll appreciate it.
You can find the workflow and written solution here if that helps: preppindata.blogspot.com/2023/06/2023-week-22-solution.html?m=1
The purple cursor looks good 😀
I'm back 🙂
Subbed&Liked!! This channel needs S M Z E U S!!!
I definitely counted zeros for M and B too :) Good to know there's a Power() function. It was nice seeing how you used the replace() and contains() functions. Thank you for creating this video!
I learned about the Rename Fields feature. So cool!!!! You can rename a lot of fields all at once. Changing the Data Type for 'Account Holder ID' to String was a simple and smart solution.
It's such a great feature that snuck in! Glad you enjoyed the solution :D
I did both pivots in the same step too. But, the wildcard search to pivot was new to me. Also, I did ABS( [Difference in Average Rating ] )> 0 AND ABS( [Difference in Average Rating ] )<1 to get 'Neutral,' where I could have just used Else :) Thanks for the video!
It's great that you're learning new tips and tricks even after you've successfully completed the challenges yourself :)
@@PreppinData Thank you!!
The format of my dates is different. I have MM/DD/YYYY. How can I change it to DD/MM/YYYY?
Hi Paola, do you mean for the Date of Birth field or the Joining Date Field?
Hello! I'm stuck @4:06. I got through to the "duplicate DOB column" step, but then The Convert Dates - Custom Fiscal Year options won't show up no matter where I look. I'm in Tableau Public.
Unfortunately this option is only available in tableau prep builder, not in the Tableau public version. You can always download the free trial if you'd like to play with that software 🙂
Hi! Thanks so much for sharing the solution. I'm following this to do the challenge but got stuck with the Join 3. For some reason the tables doesn't join correctly, there is no match results for me which I couldn't understand. Is there some potential reasons that you could think of?
You guys need to fix the sound check on your videos, they're almost muted
Most underrated channel, thank you for giving free knowledge
Thanks for your support 🙌
That was one heck of a challenge .
we need to see the changes you made to the targets table

any solutions in python? would love to see how the fixed window functions are executed in pytthon
Hi Ahmad, if you go onto twitter and search for #PreppinData, you'll see many solutions in python. Some are even shared on github :)
Amazing! Very elegant solution. This just saved us so much time.
man- ‘sup?.you sharedo utstanding -=)
the challenge needed to be explained better. it was a good exercise none the less
Very good explanation ! Thanks
holy crap, even a free tool like easymorph has a step to do filldown. I am horrified to see this.
Could you do these challenges in power query as well please.
Great idea, would love to see what you come up with!
I used REGEXP to extract codes from commentary
Hi can we do same project in tableau desktop to get same output.
some of these steps are certainly possible in desktop too
This series of tutorials is impressive!
Great video! What if you don't have any fields that could help you infer the order of the values? In this case, let's say that you simply don't have the [Row ID] field. Is there any way to create such Row ID or internal Index within TP?
Currently without an ordinal field this is difficult to achieve in Tableau Prep alone unfortunately
@@PreppinData I've been asking for this feature since 2018 :(
Hi There, i'm new to Tableau, i'm tying to create Dashbaord for Incident management team, do we really need Tableau Prep for calculating SLA or Can we do it in Tableau Desktop?
Hi Unni, it's certainly possible to do SLA calculations in Tableau Desktop too. You can do date scaffolding within the data source pane, or use some date calculations such as: www.theinformationlab.co.uk/2017/05/22/calculate-working-days-dates-tableau/
I enjoy your vid, but could you increase your audio? I'm guessing you're using a mic that is further away from you. I would recommend a lapel mic for a boost in clarity. Tks.
Thanks for the tip!
Thank you for the detailed explanation!
Amazing Solution, easier than one i used
