Hi Mars3442
You can try the following code
=Table.ReplaceValue(the last step name,e.g #"Changed Type",each [Status],each if [#"Source.Delay/Late Reason"]<>"" then [#"Source.Delay/Late Reason"] else [Status] ,Replacer.ReplaceValue,{"Status"})Output
Or you can put the following code to advanced editor
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUtJRcknNySxLLUpNUYrViVYKKUrMKy7IL0osyczPA8qCBWE0LkkkI2IB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Source.Delay/Late Reason" = _t, Status = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Source.Delay/Late Reason", type text}, {"Status", type text}}), #"Replaced Value" = Table.ReplaceValue(#"Changed Type",each [Status],each if [#"Source.Delay/Late Reason"]<>"" then [#"Source.Delay/Late Reason"] else [Status] ,Replacer.ReplaceValue,{"Status"}) in #"Replaced Value"Best Regards!

Hi, Mars3442 try this
let
Source = table_like_this,
replace =
Table.ReplaceValue(
Source,
"",
each [#"Source.Delay/Late Reason"],
(value, old, new) => new ?? value,
{"Status"}
)
in
replace
Why don't you simply add new column to check if "Source.Delay/Late Reason" is null ? Then remove old Status column. That's easier and must be faster.
