    Hi Anonymous ,

     

    Here I created a sample for your reference.M code for your reference. 

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcslMzyxJzFFwzUstSq9UCClKzCtOTC7JzM9LzFGK1YlW8sjPTVVIzEtRcMksLinKTCoFyYFlfPLLFcLyc0oS01Ox6Av1cwwO9nT3c3WBcoMDXJ093TxB/FgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"Current Value" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Current Value", type text}}),
    #"AllReplace" = [#"Digital Energy Transactional" = "BMP", #"Home and Distribution" = "BMP", #"Low Voltage Transactional" = "BMP",#"UNASSIGNED" = "BMP",#"UNSPECIFIED" = "BMP"],
    #"Replaced Value" = Table.TransformColumns(#"Changed Type",{{"Current Value",each Record.FieldOrDefault(AllReplace,_,_)}})
in
    #"Replaced Value"

     

    BTW, Pbix as attached.

Hello,

You can use the if else statements to replace multiple categories in a single power query replace value formula.
For example, If you have a status column with the values A,I,T and wish to replace them with Active, Inactive, and Terminated use the formula provided below.

= Table.ReplaceValue(
#"Filtered Rows", 
each [Status],
each if [Status] = "A" then "Active" else if [Status] = "I" then "Inactive" else "Terminated",
Replacer.ReplaceValue,{"Status"}
)
