Hello guys, so i have a function ("flecheD"),
(ColChild,ColParent,ParentActuel,source)=>
let
mylist=Table.Column(Table.SelectRows(source,each Record.Field(_,ColParent)=ParentActuel),ColChild),
resultat=Text.Combine(mylist)
in
Text.Trim(
if resultat ="" then "" else # resultat &"|" & # flecheD(ColChild,ColParent,resultat,source),"|")
which loops through 2 columns (Parent,Child) to get all children of the main parent (output->Children column). The problem is that when the function is confronted with several children, the resultat variable no longer has a single letter/child but several, which blocks the function from looking for the other sub-children.
In order to solve this, I tried to create a custom function "SubChilldren" with List.Generate()
(children as text, ColChild,ColParent,source)=>
let
i = 1,
length = Text.Length(children),
subchildren = List.Generate( ()=>#flecheD(ColChild,ColParent,Text.At(children,i-1),source), i<=length, i+1 )
in
Text.Combine(subchildren)
which when coupled with my initial function
(ColChild,ColParent,ParentActuel,source)=>
let
mylist=Table.Column(Table.SelectRows(source,each Record.Field(_,ColParent)=ParentActuel),ColChild),
resultat=Text.Combine(mylist)
in
Text.Trim(
if resultat ="" then "" else if Text.Length(resultat) = 1 then # resultat &"|" & # flecheD(ColChild,ColParent,resultat,source)
else #resultat &"|"& SubChildren(resultat,ColChild,ColParent,source),"|")
should normally get the sub-children of each children. However, it doesnt work . Could you please help me . Thx
I thought this was a fun way, but you could write a recursive function as well. I have it hard coded to 4 levels of children deep
(not sure how in your source data D child can have two parents, c and J, but whatever)
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Grouped Rows" = Table.Group(Source, {"Parent"}, {{"data", each List.RemoveNulls(_[Child]), type list}}),
Parent_List = List.Buffer(#"Grouped Rows"[Parent] ),
Child_List = List.Buffer(#"Grouped Rows"[data] ),
Process = (n as list) as list =>
let children = List.Transform(List.Transform(n, each Text.ToList(_)), each Text.Combine( List.Distinct(List.Combine(List.Transform(_, each try Child_List{List.PositionOf( Parent_List, _ )} otherwise null))))) in children,
Level1=Process(Source[Parent]),
Level2=Process(Level1),
Level3=Process(Level2),
Level4=Process(Level3),
Final=List.Transform(List.Positions(Level1),each Level1{_}&"|"&Level2{_}&"|"&Level3{_}&"|"&Level4{_}&"|"),
#"Replaced Value" = Table.ReplaceValue(Table.FromList(Final),"||","",Replacer.ReplaceText,{"Column1"}),
custom1 = Table.ToColumns(Source) & Table.ToColumns(#"Replaced Value"),
custom2 = Table.FromColumns(custom1,Table.ColumnNames(Source) & {"Children"})
in custom2
edited to be generic so it can take text as well as numerical inputs
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Parent", type text}, {"Child", type text}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Parent"}, {{"data", each List.Transform(List.RemoveNulls(_[Child]), each Text.From(_)), type list}}),
Parent_List = List.Buffer(List.Transform(#"Grouped Rows"[Parent], each Text.From(_))),
Child_List = List.Buffer(#"Grouped Rows"[data]),
Process = (n as list) as list =>let children = List.Transform(List.Transform(n, each Text.Split(_,",") ) , each try Text.Combine(List.Distinct(List.Combine(List.Transform(_, each try Child_List{List.PositionOf( Parent_List, _ )} otherwise ""))),"," ) otherwise "") in children,
Level1=Process(#"Changed Type"[Parent]),
Level2=Process(Level1),
Level3=Process(Level2),
Level4=Process(Level3),
Final=List.Transform(List.Positions(Level1),each Level1{_}&"|"&Level2{_}&"|"&Level3{_}&"|"&Level4{_}&"|"),

custom1 = Table.ToColumns(#"Changed Type") & Table.ToColumns(#"Replaced Value"),

I am a bit new to powerquery and need some help with the points specified below the code.
I have a piece of working code that does the following:
Load the source
find the max "series" of a row, the format is a mix of letters and numbers, i.e. Y21Q3S1, the letters stay the same and the numbers are increasing (year, quarter, and series).
I want to look if a certain tag is assigned to a row, so I search all the tag columns if a tag is present and write that in the "Tags" column and "none" if there were none found
through grouping I find the points per tag, for each "max series"
I finally present it in a table in excel with first column being the series, then a column for the Tags as well as a column "None" if none of the Tags were present. I add a last updated date column.
The code:
let
Source = Csv.Document(Web.Contents("somefile.csv"),[Delimiter=",", Columns=32, Encoding=65001, QuoteStyle=QuoteStyle.None]),
#"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
#"Changed Type with Locale" = Table.TransformColumnTypes(#"Promoted Headers", {{"Custom field (Points)", type number}}, "en-GB"),
#"Added Custom" = Table.AddColumn(#"Changed Type with Locale", "Max Series", each List.Max({[Series], [Series_1], [Series_2], [Series_3], [Series_4]})),
Tags = Table.AddColumn(#"Added Custom", "Tags", each if List.Contains({[Tags], [Tags_7], [Tags_8], [Tags_9], [Tags_10], [Tags_11], [Tags_12], [Tags_13], [Tags_14], [Tags_15], [Tags_16], [Tags_17], [Tags_18], [Tags_19], [Tags_20], [Tags_21], [Tags_22], [Tags_23]}, "tag1") then "tag1"
else if List.Contains({[Tags], [Tags_7], [Tags_8], [Tags_9], [Tags_10], [Tags_11], [Tags_12], [Tags_13], [Tags_14], [Tags_15], [Tags_16], [Tags_17], [Tags_18], [Tags_19], [Tags_20], [Tags_21], [Tags_22], [Tags_23]}, "tag2") then "tag2"
else if List.Contains({[Tags], [Tags_7], [Tags_8], [Tags_9], [Tags_10], [Tags_11], [Tags_12], [Tags_13], [Tags_14], [Tags_15], [Tags_16], [Tags_17], [Tags_18], [Tags_19], [Tags_20], [Tags_21], [Tags_22], [Tags_23]}, "tag3") then "tag3"
else "zzzNone"),
RemoveDummy = Table.SelectRows(Tags, each [ID] <> "ID-1234"),
#"Grouped Rows" = Table.Group(RemoveDummy, {"Max Series", "Tags"}, {{"Points per Tags", each List.Sum([#"Custom field (Points)]), type number}}),
#"Sorted Rows" = Table.Sort(#"Grouped Rows",{{"Tags", Order.Ascending}}),
#"Pivoted Column" = Table.Pivot(#"Sorted Rows", List.Distinct(#"Sorted Rows"[Tags]), "Tags", "Points per Tags"),
#"Renamed Columns" = Table.RenameColumns(#"Pivoted Column",{{"zzzNone", "None"}, {"Max Series", "Series"}}),
#"Added Custom1" = Table.AddColumn(#"Renamed Columns", "Last update", each DateTime.LocalNow()),
#"Changed Type1" = Table.TransformColumnTypes(#"Added Custom1",{{"Last update", type datetime}})
in
#"Changed Type1"
The "Series" and "Tags" columns are a multivariable field, containing all series and tags and is translated by excel into multiple columns. The issue is that the number of series and tags are changing and to try coping with this I have created a dummy row with a lot of series. However, as you can see from the code this also changes and somehow "Tags_2" to "Tags_6" has disappeared and I had to error correct by removing these from the code.
Is there a dynamic way to if any column "Tags_*" contains "tag1" then... so I don't have to hard-code this?
Same goes for the "Max Series" where I would like to dynamically take max value of any columns "Series_*"
I would like to make the “Tags” step more dynamic, so that I can take input from a table in the excel sheet specifying which tags I want to search for instead of hardcoding “tag1, “tag2” etc.
My current code only assigns the points to the first tag found. However, I would like to assign points to several tags, so if two tags were found the "points" be assigned with half to each and for 3 tags they would all get one third of the points. I don’t know how to do this. Could you help me here?
As I am a bit new powerquery my code might be far from optimal, if you have some suggestions in your answers on how I can improve it that would be highly appreciated :-)
Hi mitru and welcome to StackOverflow!
You can make the 'Tags' step automatic by 'Unpivot other columns' and 'Group by' operations. To obtain this you should select all non Tag* columns and use 'Unpivot other columns'. Then please perform a Group by operation with operation = All Rows
You will receive a column populated with tables. The next step is to create a Custom columns with following formula:
=if List.Contains([Tags][Value],"tag1") then "tag1"
else if List.Contains([Tags][Value],"tag2") then "tag2"
else if List.Contains([Tags][Value],"tag3") then "tag3"
else "zzzNone"
The [Tags] is the column containing tables while [Value] is the column within each table that contains tags you are looking for.
Under below link there is a file with sample solution that I created.
https://sendeyo.com/en/608c8dee7f
Regarding bullet 3. I am not sure how the scoring system should work. Can you provide a sample data with the final output?
With the help from Gonso's post I was able to make the "tags" step more dynamic.
Furthermore, I found a solution on the bullet 3 assigning points to different tags if more than one tag is present.
I am posting the updated code here in case anyone else find the solution helpful:
let
Source = Csv.Document(Web.Contents("somefile"),[Delimiter=",", Columns=50, Encoding=65001, QuoteStyle=QuoteStyle.None]),
Promoted_Headers = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),

Max_Series = Table.AddColumn(Changed_Type_with_Locale, "Max Series", each List.Max({[Series], [Series_1], [Series_2], [Series_3], [Series_4]})),
Unpivoted_Other_Columns = Table.UnpivotOtherColumns(Max_Series, {"Type", "ID", "Custom field (Points)", "Series", "Series_1", "Series_2", "Series_3", "Series_4", "Series_5", "Series_6", "Series_7", "Series_8", "Series_9", "Max Series"}, "Attribute", "Value"),
Tags = Table.Group(Unpivoted_Other_Columns, {"Type", "ID", "Custom field (Points)", "Series", "Series_1", "Series_2", "Series_3", "Series_4", "Series_5", "Series_6", "Series_7", "Series_8", "Series_9", "Max Series"}, {{"Tags", each _, type table [Type=nullable text, ID=nullable text, #"Custom field (Points)"=nullable number, Series=nullable text, Series_1=nullable text, Series_2=nullable text, Series_3=nullable text, Series_4=nullable text, Series_5=nullable text, Series_6=nullable text, Series_7=nullable text, Series_8=nullable text, Series_9=nullable text, Max Series=text, Attribute=text, Value=text]}}),

Tag2_update = Table.ReplaceValue(Tag_update, each [Tag2], each if [Tag2] > 0 then ([#"Custom field (Points)"] * ([Tag2] / [Tag_total])) else [Tag2],Replacer.ReplaceValue,{"Tag2"}),
Tag3_update = Table.ReplaceValue(Tag2_update, each [Tag3], each if [Tag3] > 0 then ([#"Custom field (Points)"] * ([Tag3] / [Tag_total])) else [Tag3],Replacer.ReplaceValue,{"Tag3"}),
TagNone_update = Table.ReplaceValue(Tag3_update, each [TagNone], each if [TagNone] > 0 then ([#"Custom field (Points)"] * ([TagNone] / [Tag_total])) else [TagNone],Replacer.ReplaceValue,{"TagNone"}),
RemoveDummy = Table.SelectRows(TagNone_update, each [ID] <> "ID-1234"),
Grouped_Series = Table.Group(RemoveDummy, {"Max Series"}, {{"Tag1", each List.Sum([Tag1]), type number}, {"Tag2", each List.Sum([Tag2]), type number}, {"Tag3", each List.Sum([Tag3]), type number}, {"None", each List.Sum([TagNone]), type nullable number}}),

I have a list in Excel like the following:
1 / 6 / 45
123
1546
123 456
1247 /% 456 /
I want to create a new column with all sequences of consecutive non digits replaced by a character. In Google Sheets, this is easy using =REGEXREPLACE(A1&"/","\D+",","), resulting in:
1,6,45,
123,
1546,
123,456
1247,456,
In that formula A1&"/" is needed in order for REGEXREPLACE to work with numbers. No big deal, just adds a comma at the end.
How can we do this in Excel? Pure Power Query (not R, not Python, just M) is very much encouraged. VBA and other clickable Excel features are unacceptable (like find and replace).
If you have Excel 365:
In B1:
=LET(X,MID(A1,SEQUENCE(LEN(A1)),1),SUBSTITUTE(TRIM(CONCAT(IF(ISNUMBER(--X),X," ")))," ",","))
Or if streaks of digits are always delimited by at least a space:
=TEXTJOIN(",",,FILTERXML("<t><s>"&SUBSTITUTE(A1," ","</s><s>")&"</s></t>","//s[.*0=0]"))
Another option, if you have got access to it, is LAMBDA(). Make a function to replace all kind of characters, something along the lines of this. Without LAMBDA() and TEXTJOIN() I think your best bet would be to start nesting SUBSTITUTE() functions.
Here is a Power Query solution.
It makes use of the List.Accumulate function to determine whether to add a digit, or a comma, to the string:
Note that the code replicates what you show for results. If you prefer to avoid trailing (and/or leading) commas, it can be easily modified.
let
Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "textToList", each List.Combine({Text.ToList([Column1]),{","}})),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "commaTerminators", each List.Accumulate(
[textToList],"", (state,current) =>
if List.Contains({"0".."9"},current)
then state & current
else if Text.EndsWith(state,",")
then state
else state & ",")),
#"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"textToList"})
in
#"Removed Columns"
Edit To eliminate leading/trailing commas, we add the Text.Trim function which, in Power Query, allows defining a specific text to Trim from the start/end:
let
Source = Excel.CurrentWorkbook(){[Name="Table5"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "textToList", each List.Combine({Text.ToList([Column1]),{","}})),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "commaTerminators", each
Text.Trim(
List.Accumulate(
[textToList],"", (state,current) =>
if List.Contains({"0".."9"},current)
then state & current
else if Text.EndsWith(state,",")
then state
else state & ","),
",")),
#"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"textToList"})
in
#"Removed Columns"
VBA UDF You mentioned you did not want VBA, but not clear if you were restricting that to a "clickable". Here is a user defined function that you can use on a worksheet directly. It uses the VBA regex engine which allows easy extraction of multiple matches
You can enter a formula on the worksheet such as =commaSep(cell_ref) to get the same results as shown above in my second PQ example
Option Explicit
Function commaSep(S As String) As String
Dim RE As Object, MC As Object, M As Object
Dim sTemp As String
Set RE = CreateObject("vbscript.regexp")
With RE
.Global = True
.Pattern = "\d+"
If .test(S) Then
Set MC = .Execute(S)
sTemp = ""
For Each M In MC
sTemp = sTemp & "," & M
Next M
commaSep = Mid(sTemp, 2)
Else
commaSep = "no digits"
End If
End With
This is another variation if you have TEXTJOIN function available.
=SUBSTITUTE(TRIM(TEXTJOIN("",TRUE,IFERROR(MID(A2,ROW($A$1:INDEX(A:A,LEN(A2))),1)+0," ")))," ",",")
And another option in Power Query.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTQVzADYhNTpVgdINfIGEKbmpjBBIByZgpQjom5gr4qWEBfKTYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
x1 = Table.AddColumn(#"Changed Type", "x1", each Text.ToList([Column1])),
x2 = Table.AddColumn(x1, "x2", each List.Transform([x1], each if Text.Contains("0123456789", _) then _ else " " )),
x3 = Table.AddColumn(x2, "x3", each Text.Split(Text.Combine([x2])," ")),
x4 = Table.AddColumn(x3, "x4", each List.Transform([x3], each if Text.Contains("0123456789", try Text.At(_,0) otherwise " ") then _&"," else "" )),
x5 = Table.AddColumn(x4, "x5", each Text.Combine([x4])),
#"Removed Columns" = Table.RemoveColumns(x5,{"x1", "x2", "x3", "x4"})
in
#"Removed Columns"
How do you figure out what workbook a query in Excel points to?
After much back and forth I managed to come up with the following sub, which produces a string I can extract the name and path of the workbook from, but I feel there ought to be a simpler way to find this info? Am I missing something.
The sub I've produced is
Sub test()
Dim wbq As WorkbookQuery
For Each wbq In ThisWorkbook.Queries
Debug.Print wbq.Formula
Next wbq
End Sub
which prints something like
let
Source = Excel.Workbook(File.Contents("[what I want]"), null, true),
Sheet2 = Source{[Name="Sheet1"]}[Data],
#"Removed Columns" = Table.RemoveColumns(Sheet2,{"Column2", "Column3", "Column4", "Column5", "Column6", "Column7", "Column8", "Column9", "Column10", "Column12", "Column13", "Column14", "Column15", "Column16", "Column17", "Column18"}),
#"Removed Top Rows" = Table.Skip(#"Removed Columns",4),
#"Promoted Headers" = Table.PromoteHeaders(#"Removed Top Rows", [PromoteAllScalars=true]),
#"Removed Blank Rows" = Table.SelectRows(#"Promoted Headers", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null})))
in
#"Removed Blank Rows"
My understanding is there is no simpler way than what you've shown. The query is written in M/Power Query Formula language -- which, to my knowledge, can't be evaluated, or interfaced with, in VBA.
I think the best you can do is to get the WorkbookQuery.Formula (as you're currently doing) and resort to string matching to try to extract the path being passed.
This is fine when the path is hard coded within the call to Excel.Workbook(File.Contents("...")) (as in your example), but harder if indirection is involved and the function is being passed an identifier/variable -- as you end up trying to re-create parts of the language's evaluation engine.
But maybe someone else can tell you differently.
I'm having multiple PowerQuery queries that I would like to feed the value of a cell in my Excel file. In this particular case, the full path to the sourcefile name.
Is there any way I can get this into PowerQuery?
This can be achieved using a named range and a custom function in PowerQuery:
Name the cell you need to refer (type in a name into the file left of the formula bar) - e.g. SourceFile
Insert a new blank PowerQuery query (PowerQuery ribbon -> From other sources)
In the PowerQuery editor, go to View -> Advanced Editor and paste the following code;
(rangeName) =>
Excel.CurrentWorkbook(){[Name=rangeName]}[Content]{0}[Column1]
Name the query to GetValue (Name property in the Query settings pane on the right)
Now you can access the named cell in your queries, using GetValue(cellName) - e.g.
= Excel.Workbook(File.Contents(GetValue("SourceFile")))
If the cell is part of an Excel table, the above is not needed - you can import/access that table's data directly using the "From Table/Range" button in the "Data" ribbon.
I couldn't get the => syntax to work so what I ended up with is as below. Here I'm using a single table to store all the values but you could also use named ranges and stick to using [content]{0}[Column1] for each one.
let
SITE_URL_VALUE = Excel.CurrentWorkbook(){[Name="SETTINGS_TABLE"]}[Content]{0}[Value],
FOLDER_PATH_VALUE = Excel.CurrentWorkbook(){[Name="SETTINGS_TABLE"]}[Content]{1}[Value],
FILENAME_VALUE = Excel.CurrentWorkbook(){[Name="SETTINGS_TABLE"]}[Content]{2}[Value],
Source = SharePoint.Files(SITE_URL_VALUE, [ApiVersion = 15]),
#"Import Filename" = Source{[Name=FILENAME_VALUE, #"Folder Path"=FOLDER_PATH_VALUE]}[Content],
#"Import Workbook" = Excel.Workbook(#"Import Filename"),
#"Import Table" = #"Import Workbook"{[Item="ACTIVITY_PLAN_TABLE",Kind="Table"]}[Data],
#"Removed Other Columns" = Table.SelectColumns(#"Import Table",{"Work Order", "MAT", "Exp Hours", "OSC", "Team", "Plant", "Area", "Hours", "Complete", "Plan Status"}),
#"Changed Type" = Table.TransformColumnTypes(#"Removed Other Columns",{{"Work Order", type text}, {"MAT", type text}})
in
#"Changed Type"
