Tranpose rows to columns

Select column named Steps - Transform tab - Pivot column

In values, choose Action

under Advanced options, choose Don't Aggregate

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. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("nc/BCoMwDMbxVyk9Cy5JB/oc2016EKkScHa0eX8WD4XtUnW3r/AL/DsM1rXgWrwh2sYCINI+HhLeBnSksHCWkKxvahS/qJniNnN6jcJxO7gjHWqzmDUufKSdjoqj8+H0ZzhdCqer4ffizDzyWnBXcNf3P398hixQVftbVKH1/gM=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, ID = _t, Steps = _t, Action = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"ID", Int64.Type}, {"Steps", type text}, {"Action", type text}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Steps]), "Steps", "Action")
