Month id to month name using power query

[stefans124]

Hello there, im having a little challenge with my dash board. 

Here i have a slicer, that is connected to all other tables and makes them change information based on the month selected. So i have an issue with changing these 20221, 20222 etc. to their month names  (respectively, 20221 needs to be january, 20222 needs to be february etc.) I wanted to ask for help on how to do it, so that my slicer shows the names of the month not these numbers, and im skeptical that if i change it based on "how it think it should be done" then the relationships between tables might vanish.

I appreaciate your time for reading this and any help or solution will be appreciated 🙂

Hi @stefans124 ,

You may firstly try @SpartaBI 'method using M in Power Query.

Mine is using DAX to create calculated columns:

Month Number = CONVERT( RIGHT([id_menesis], LEN([id_menesis])-4),INTEGER)

Month Name = FORMAT( DATE(LEFT([id_menesis],4),[Month Number],1),"mmmm")

Output:

Hi @stefans124,

Have a look at the following code

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMjJUitWBsIzgLGM4ywTOMoWzzOAsczjLAs6yhLMMDRBMhC2GQGtiAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [id_menesis = _t]),
    AddMonthName = Table.AddColumn(Source, "MonthName", each Date.ToText(Date.FromText([id_menesis],[Format="yyyyM"]),"MMMM"),type text),
    AddMonthNum = Table.AddColumn(AddMonthName, "MonthNum", each Int64.From(Text.Middle([id_menesis], 4,2)), Int64.Type)
in
    AddMonthNum

You will need the MonthNum integer column to sort the month names. See this link
