Here comes some long awaited comfort functions for part 2 of my easy P&L series, where you don't have to define the single accounts any more.

Today I discovered that we can use conditions in many of the N-selecting functions where one/I would normally expect just a number-expression for the N: Table.RemoveFirstN( table as table, optional countOrCondition as any) (…) Read more

The other day when I was thinking about Power Query functions (as you do) it occurred to me that they would be a lot more usable if, when you invoked them, you could show your users a dropdown box …

Select Table 2, click the Query tab, and click Reference. This will create a new query that references Table 2 and will allow us to add a lookup column without enabling Fast Combine.Add a custom column with the following formula: List.First(List.Select(Table1[Product],(productName) = Text.Contains(productName, [Product])))Viola!

I answered some forum questions recently that were similar in nature and I thought they would make a good blog article. The scenario is this: there is a ta

Year ago I wrote a post Transform table column using own function in Power Query. According to stats, it is quite popular topic, and I’m not surprised. However, I think that old post is quite…

Power Query’s Text.Trim function doesn’t clean whitespace inside the text string, only at the ends. This article shows a custom function that does.

let Source = Excel.CurrentWorkbook(){[Name="Table4"]}[Content], Subtotals = Table.Group(Source, {"Category"}, {{"Category Sales", each List.Sum([Sales]), type number}}), JoinTables = Table.Join(Source, "Category", Subtotals, "Category"), InsertedCustom = Table.AddColumn(JoinTables, "Share", each [Sales]/[Category Sales]), RemovedColumns = Table.RemoveColumns(InsertedCustom,{"Category Sales"})in RemovedColumns

Follow Me In today’s tutorial we will solve a very common challenge in Excel.

For example, In the screenshot …

Quite often, in Power Query, you want to

let fxContain = (txt as text, idx as number) = let Result = if Text.Contains(txt,ListB{idx}) then ListB{idx} else if idx = ListCountB then null else @fxContain(txt,idx+1) in Result, ListA = {"help me rhonda", "in my room", "good vibrations", "god only knows"}, ListB = {"room", "me", "only", "help"}, ListCountB = List.Count(ListB)-1, ListC = List.Transform(ListA, each fxContain(_,0))in ListC

Hi bjzk. You're going to have issues if you use Table.ColumnNames(GetH123Prices) to derive the equivalent of ColumnList in my example. Instead, you'll need to specify the names of the columns you want to check against (or use a formula to automatically whittle down the list of column names to exclude H0 and any other columns you don't want to check). For example:= Table.AddColumn(GetH123Prices, "ContainsH0", each List.Contains(Record.FieldValues(Record.RemoveFields(_, "H0_Price")), [H0_Price]))EhrenTuesday, August 09, 2016 6:26 PMReply | QuoteEhren - MSFTMicrosoft (MSFT) 6,290 PointsOwner

let fxContain = (txt as text, idx as number) = let Result = if Text.Contains(txt,ListB{idx}) then ListB{idx} else if idx = ListCountB then null else @fxContain(txt,idx+1) in Result, ListA = {"help me rhonda", "in my room", "good vibrations", "god only knows"}, ListB = {"room", "me", "only", "help"}, ListCountB = List.Count(ListB)-1, ListC = List.Transform(ListA, each fxContain(_,0))in ListC

This article describes how you can store tables longer than 1,1 Mio rows in an Excel-sheet using Power Query and JSON compression.

Recently I was asked by a customer to do some tuning on an Excel workbook with a lot of Power Query queries in it. Although all of the data used in the queries was coming from tables in the workboo…
