    Use this (Replace #"Changed Type" with your previous step)

    = Table.ReplaceValue(#"Changed Type",each [Column B], each if [Column A]="Development" then  "Developing" else [Column B], Replacer.ReplaceValue,{"Column B"})

    See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately)

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckktS83JL8hNzStR0lHyL8pMz8xLzFGK1YlW8k8qTi0qSyzJzM9Dl0LVFZSqC2QUVWKR8i/JSC0CizsmJealYJqEZIkCilwsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Column A" = _t, #"Column B" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column A", type text}, {"Column B", type text}}),
    Custom1 = Table.ReplaceValue(#"Changed Type",each [Column B], each if [Column A]="Development" then  "Developing" else [Column B], Replacer.ReplaceValue,{"Column B"})
in

Sorry but what previous step are you referring to? 

 

And where do I input that script?
