I found one solution

 

let
    Source = Web.Page(File.Contents("example.com\test.html")),
    Data0 = Source{0}[Data],
    #"Renamed Columns" = Table.RenameColumns(#"Data0", List.Transform(Table.ColumnNames(Data0), each {_, if Text.Contains(_, "Total") then Text.Replace(_, "NEED SELECT UNKNOWN NAME", "Solved") else Text.Replace(_, " ", "Fail")}))
in
    #"Renamed Columns"


But it did not help me completely.
It remains to find the command which allows you to replace any name of the column.
Since I do not know the exact name of the column.

    Hi a1i3n,

     

    Based on my test, the formula below should work in your scenario. :smileyhappy:

    let
    Source = Web.Page(File.Contents("example.com\test.html")),
    Data0 = Source{0}[Data],
    #"Get Columns Names" = Table.FromList(List.Select(Table.ColumnNames(Data0),each Text.Contains(_, "Total"))),
    #"Added Custom" = Table.AddColumn(#"Get Columns Names", "Custom", each Text.Start([Column1],14) ),
    Rename = Table.RenameColumns(Data0, Record.ToList(Table.ToRecords(#"Added Custom"){0}))
    
in
    Rename

     

    Regards
