I want to remove all empty columns, what is the quickest way to do this?

Solved! Go to Solution.
It's probably easier to paste the function code as a separate query like described here:

Transpose, Remove Empty Rows, Transpose
in the advanced Editor, you'd have:
#"Transposed Table" = Table.Transpose(Last step),
#"Removed Blank Rows" = Table.SelectRows(#"Transposed Table", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null}))),
#"Transposed Table1" = Table.Transpose(#"Removed Blank Rows")
Best Soluthion I found if you have a smaller size area to collect data.
https://www.mrexcel.com/forum/excel-questions/924666-deleting-blank-columns-power-query.html
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], Reorganized = Table.FromColumns({Table.ColumnNames(Source),Table.ToColumns(Source)}), #"Added Custom" = Table.AddColumn(Reorganized, "IsNull", each if List.NonNullCount(List.Distinct([Column2]))=0 then "Yes" else "No"), #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([IsNull] = "No")), #"Clean Table" = Table.SelectColumns(Source,Table.Column(#"Filtered Rows","Column1")) in #"Clean Table"
You just have to replace the source with the table on which you want to apply the operation
Hi @vanessafvg
Do you mean other than right clicking the header and select remove? Or Highlight the ones you want to keep and select 'Remove Other columns. Or, you can select the 'Choose columns' button on the ribbon and select the ones you want to keep.
Thanks

hi @shebr i want to programmatically via M remove them all without having to click on each one.

You can use this function:
(tbl as table) => let Headers = Table.ColumnNames(tbl), Result = Table.SelectColumns( tbl, List.Select(Headers, each List.MatchesAny(Table.Column(tbl, _), each _ <> null))) in Result

@ImkeF thats great thank you, one last question
if i wanted to add this into this sample file transformation as a result from combinining binaries, i can't quite figure out how to combine the code with the function, i have tried but im obviously not quite understanding what needs to be done
this is the mcode
let
Source = Excel.Workbook(#"Sample File Parameter7", null, true),
#"Service Report_Sheet" = Source{[Item="Service Report",Kind="Sheet"]}[Data]
in
#"Service Report_Sheet"
this is what i tried
let
Source = Excel.Workbook(#"Sample File Parameter7", null, true),
#"Service Report_Sheet" = Source{[Item="Service Report",Kind="Sheet"]}[Data],
tbl = table,
Headers = Table.ColumnNames(tbl),
#"Result" = Table.SelectColumns(
tbl,
List.Select(Headers, each List.MatchesAny(Table.Column(tbl, _), each _ <> null)))
in
#"Result"
i get this error Expression.Error: The import table matches no exports. Did you miss a module reference?
