Say I have a column with Text data like:
A
B
A
D
I would like to create a new column so that the end result is:
A 0
B 1
A 0
D 2
What is the correct way do this is PowerBI Power Query Editor? I tried a few things like indexing but that gives a unique value to every row. Not very familiar with the API so am a bit stuck here.
We can do something like: List.PositionOf(List.Distinct(Table.Column( #"Table name", "Col")), [Col]))
where Col is the column name.

Is there a function in Power BI that can check whether a list of specified values (numbers) exists in a column?
For example, in the image below, I have a column with some values and another one with 0 and 1s. You can see that some values are marked with 1 and some with 0. In order to do this, I used IF function, but this is just too cumbersome.
I am looking for a formula that can check if the values from a list like {XXXX, XXXX, XXXX, etc} exist in a column and that can easily be edited when I need to add other values.
Thank you and have a good day!
Best,
Denis
You can do that by adding a custom column for example. If we assume your table is named Table and first column is named Value, then add a custom column like this:
Where the list contains all the values of interest. This will give you a boolean column Flag:
If you want an integer column with 0 and 1 values, then change the column to something like this:
= if (List.Contains({"5006", "4905"}, [Value])) then 1 else 0
Using Google Sheets, I'm trying to do something specific that is apparently un-searchable (zero results).
Sheet 1 contains data in column A. I want to import the data in Columns A and B to their respective columns on Sheet 2, but only if that same row also has (literally any) data in Column C.
maybe this in Sheet2!A1:
=ARRAYFORMULA(IF(LEN(Sheet1!C:C), Sheet1!A:B, ))
or perhaps this:
=ARRAYFORMULA(IF(LEN(C:C), Sheet1!A:B, ))
Trying to create a new query from the existing "Master" Query using below formula:
let
Source = Table.SelectColumns('Original Source Name',{'Column Name','Column Name2'})
in
Source
which works fine, however I am looking to see if there is any other formula which would do the same but in a way that it will create the new query with a range of columns , for example Column 30- 67 ( in this case when the original Excel file is updated, inserting a column in this range it would automatically update in the PBI too when refreshed)
Here's one possible way. If you start with this table, named Table1:
You can reference it in a new query like this:
let
Source = Table.SelectColumns(Table1, List.Range(Table.ColumnNames(Table1), 2, 3))
in
Source
...to get this:
The formula selects a range of columns from the table starting at the column at index position 2, and spanning 3 columns. (The index starts with 0.) For columns 30-67, you would change the 2 to 31 and the 3 to 37. You would change Table1 to your Original Source Name as well.

I am fairly new to powerbi and I need your help in one task on which I am stuck on.
Basically I have two tables and I need to compare the value from table one with a row of table 2 and return the output.
Table 1
I need to compare values in column a & b and get a match from table 2.
For example if row 1 has BY Green & BS HIGH then I need to check this value from matrix table below and return the output in column value as either 0 or 1.
Table 2
As you can see the Table 2 first row has value BY Green and BS low has a value '0'
Try this...
Index() returns a value from the matrix (in purple) based upon the intersections of the two match()'s. The first is the Vertical match in from the Table1:Col A; the second is the Horizontal match from table1:Col B. The value found at that intersection is returned.
... My apologies ... just saw this was a BI request... no worries...
First, Need fixup table2 as a lookup file:
First, click a cell in table 2 (don't edit), then Data menu >frm table/range, will bring up the Power Query window. Select columns B (not A) through Col F), then in the PQ Transform menu > Unpivot to create the new lookup table. this can either be saved as a new table or be used by reference.
Next, open and merge Table 1 PQ_Table 2 (Be sure to select BOTH Columns in BOTH Tables, in the same order). Then, expand the table tab following the merge expand the table tab. I only selected the value to return but you can return all the values to verify, then delete the unneeded columns.
Hope this helps...
Good Luck.
In Power BI Desktop, I'm trying to order the following column with repeated values by an ID column (contains primary key).
This returns the error: "There can't be more than one value in "Nível2"...."
In this other post it seems the suggestion is to concatenate the values of the column so they don't get duplicate.
But I want them to be repeated so they can aggregate values in visuals.
So, what's the workaround for this situation?
Thanks in advance for helping!
The issue is that your sort column (i.e. your ID column) contains multiple values for each value in the column you are trying to sort (i.e. your Nivel2 column).
You need to ensure that your sort column contains only one distinct value for each value in the column you are trying to sort.
One way to achieve this would be to create a new (calculated) sort column based on your ID column. It could be defined like this:
SortColumn:=CALCULATE(MAX('YourTable'[ID]),ALLEXCEPT('YourTable','YourTable'[Nivel2]))
Here is an example of how the SortColumn would behave:
Id Nivel2 SortColumn
1 Caixa 4
2 Caixa 4
3 Caixa 4
4 Caixa 4
5 Depósitos à ordem 7
6 Depósitos à ordem 7
7 Depósitos à ordem 7
You can now sort Nivel2 by SortColumn.
EDIT - The implementation of the SortColumn should be done in the data source
There seems to be a limitation in PowerBI where it checks the implementation of the sort column rather than the data in the sort column. Therefore the above solution does not work, even though the data in the sort column is perfectly valid. The above solution will throw this error when you attempt to sort [Nivel2] by SortColumn:
This column can't be sorted by a column that is already sorted, directly or indirectly, by this column.
The implementation of the SortColumn should be moved to the data source instead. I.e. if your data source is an Excel sheet, then the SortColumn should be created inside the Excel sheet.
The above answer does explain the issue and the resolvation correctly. The only change is that the SortColumn must be implemented outside of the tabular model (PowerBI) to ensure that PowerBI does not know about the dependency between the SortColumn and the [Nivel2] column.
In my case, I calculate the levels from a parent-child hierarchy
Path = Path([id],[father])
For each level:
Level1 = LOOKUPVALUE([Name],[id], PathItem([Path],1))
Level2 = LOOKUPVALUE([Name],[id], PathItem([Path],2))
.....
Then I created a new column for each level to sort the column Level:
SortL1 = LOOKUPVALUE([nID],[id], PathItem([Path],1))
SortL2 = LOOKUPVALUE([nID],[id], PathItem([Path],2))
.....
id and nID is the same numeric variable but "id" in string format because Path do not support numeric values.
