I have a table and each row is a different class. One of the columns has student names separated by commas. I want to make another table that shows the number of classes that the student is in. Basically, what I need is a DAX formula to combine search and countrows. The first table is what I am starting with. The second table is what I want but cannot figure out an easy way to do it.
I can only think of creating a separate table for each student and then use union to put them all together.
table 1 is what I have
Table 2 is what I want in the end
It is not possible like you want to do it, you need to redesign your first table. This datarow
Class Students
Physics A, B
has to look like this:
Class Students
Physics A
Physics B
You can do this in the under edit querys. Select the column Students and click on Transform > Split Column > By Delimiter. Chose Comma as delimiter and go to the advanced option and check the Rows option. If you hit OK you get the table like you need it to evaluate your data.

Hello M language masters!
I have a question about working with grouped rows when the Power Query creates a table with data. But maybe it is better to start from the beginning.
Important information! I will be asking for example only about adding an index. I know that there are different possibilities to reach such a result. But for this question, I need an answer about the possibility to work on tables. I want to use this answer in different actions (e.g table sorting, adding columns in group table).
In my sample data source, I have a list of fake transactions. I want to add an index for each Salesman, to count operations for each of them.
Sample Data
So I just added this file as a data source in Power BI. In Power query, I have grouped rows according to name. This step created form me column contained a table for each Salesman, which stores all his or her operations.
Grouping result
And now, I want to add an index column in each table. I know, that this is possible by adding a new column to the main table, which will be store a new table with added index:
Custom column function
And in each table, I have Indexed. That is good. But I have an extra column now (one with the table without index, and one with a table with index).
Result - a little bit messy
So I want to ask if there is any possibility to add such an index directly to the table in column Operations, without creating the additional column. My approach seems to be a bit messy and I want to find something cleaner. Does anyone know a smart solution for that?
Thank you in advance.
Artur
Sure, you may do it inside Table.Group function:
= Table.Group(Source, {"Salesman"}, {"Operations", each Table.AddIndexColumn(_, "i", 1, 1)})
P.S. To add existing index column to nested table use this code:
= Table.ReplaceValue(PreviousStep,each [index],0,(a,b,c)=>Table.AddColumn(a,"index", each b),{"Operations"})
I am rather new to Power Bi and I have a question i can't find the answer to.
I want to import a table that have some label columns, with repeated items, and more than 15 data columns.
My desire result would be to group the label columns, so no repeated items, and aggregate the values of the remaining columns.
Is there a way to do that in PQ editor or DAX ?
I appreciate any help or direction you can give me!
A sample of the table (it's much bigger, with multiple values in the first three columns)
Table Sample
Thanks a lot
Edit: From that sample, the output y I want is the following
Output Sample
The thing is, there are many different values in the first columns, and i need to agreggate all the other values, keeping they column name (cause this info is already linked to other files).
Maybe the only way is to group by and add the columns, renaming them one by one?
I want to do this in a couple of files, so if you know of another way please let me know!
In your query designer import your table. Then go to Home > Group By and group like you want it, the same goes for the aggregations and thats it.
If you just want to remove row duplicates, just group all columns which you dont want to aggregate and the rest can be aggregated like you want it.
I have a table with columns Firstname,middlename and lastname , implemented custom 'text filter' to search. How can I implement multiple search that allows user to enter a word and it should fetch among all the rows with that word matching at least one of the 3 columns.
I tried to implement by creating a new table ,check measure and measure , by union of all the columns.And this procedure is taking more space as a new table is created for it.
Is there any other way to do multiple search other than the above mentioned one so it does not increase the size of the file.
I have a string of concatenated data separated by a delimiter "; ". For example: Dog; Cat; Mouse;. (the components of the string can appear in any order leading to a large amount of possibilities)
I am trying to figure out if a custom visual or a method to query the data exists so that if I'm interested in all records that contain "Dog" I can visualize just those....
My first idea was to split the concatenated column in Query editor into 3 separate columns. Then, create a relationship between a table of distinct animals and each of the 3 columns. However, only one active relationship can exists between the distinct animals and the split columns so that's where I stopped.
If this were an excel dashboard I'd just build a VBA drop down box that sliced my data.... so I'm hoping a similar visual slicer exists somewhere....
Back in the Query Editor, after your Split, I would select all the other columns and from the Transform ribbon choose Unpivot Other Columns. This will give you 3 rows for each input row, with each animal name on a separate row.
After renaming the generated Attribute and Value columns, you can create the relationship.
Create a calc column with the FIND function.
I am essentially trying to do that this guy is trying to do:
Excel drop-down list using vLookup
I've gone through the steps and since my data set has about 400 different drop down options I am hoping there is an easier way than naming ranges. I have a list of about 400 different account names. Each of these account names is tied to a household and identified by the household ID number. A household can have anywhere from 1-5 account names. I would like for my drop down menu to be able to identify a household ID number and then provide the drop down with the account names associated with it.
Example:
Where household Id number is the identifier.
I've gone here as well http://sites.madrocketscientist.com/jerrybeaucaires-excelassistant/data-validation/dynamic-indirect and am trying to find a way to save on some of the manual work.I am a total newbie so thank you in advance for any help you can provide.
Let's pretend you have three worksheets. The first worksheet, Sheet1, is the sheet that your users will be looking at and it has the drop down lists. We'll say that the cell containing the first drop down option is in B1 (the one with about 400 different options) and the cell containing the dependent drop down is in B2:
On your second sheet, which we'll call MasterList, is all of the data options and the corresponding data. Row 1 is a header row; Row 2 and down is the actual data:
On your third sheet, which we'll call DropDownLists, is where the magic happens. It first needs to have a list of all the unique data options. I've put that in column A. You can get the unique data options from your master list through whatever means you prefer (Advanced Filter, Pivot Table, formula, VBA, etc). That list of unique data options is the basis of your drop down list for Sheet1 cell B1. Then in cell B2 of DropDownLists and copied down as far as needed to guarantee it will grab all data associated with the selected Data Option, use this formula (adjust sheet names and ranges to suit your actual data):
=IF(OR(Sheet1!$B$1="",ROW(B1)>COUNTIF(MasterList!$A$2:$A$10000,Sheet1!$B$1)),"",INDEX(MasterList!$B$2:$B$10000,MATCH(1,INDEX((MasterList!$A$2:$A$10000=Sheet1!$B$1)*(COUNTIF(B$1:B1,MasterList!$B$2:$B$10000)=0),),0)))
This makes your DropDownLists sheet look like this:
Lastly, we need to make that list (data based on the selected Data Option) a dynamic named range. I named it listFilteredData and defined it with this formula:
=DropDownLists!$B$2:INDEX(DropDownLists!$B:$B,MAX(2,ROWS(DropDownLists!$B:$B)-COUNTBLANK(DropDownLists!$B:$B)))
Then for Sheet1 cell B2, use Data Validation and define the list with =listFilteredData and you will get results as shown in my example.
Practice with this.....it will get what you need.
Your data will have to sorted for this to work.
Sorted Data
Data Validation for Shows
Data Validation for Episodes
This formula in the data validation box
=OFFSET($A$1,MATCH($E$4,$A:$A,0)-1,1,COUNTIF($A:$A,$E$4),1)
Enter the array formula to find the Duration
Must be confirmed with Ctrl & Shift & Enter
=INDEX($C$4:$C$18,MATCH(1,(E4=$A$4:$A$18)*(F4=$B$4:$B$18),0))
