Replace future dates by today date

Hello NumeroENAP 

as far as I know the function Table.ReplaceValue just replaces and old value with a new value. Use this syntax instead (not tested)

= Table.TransformColumns
  (
      #"Column", 
      {
         {
            "Date created", 
            each if _ > Date.From(DateTime.FixedLocalNow()) then Date.From(DateTime.FixedLocalNow()) else _,
            type date
         }
      }
   )

Kudoes are nice too

Have fun

Try:

= Table.ReplaceValue(#"Column", "Date created", each if DateTime.FromText([Date created])> DateTime.FixedLocalNow() then DateTime.FixedLocalNow() else [Date created])
