[11738495,249238575]

[764548304,198378475,295767604,104956864]

[183765663,1857569403]

// Table1
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    ETAD = Table.TransformColumns(Source, {{"Currently", each Text.AfterDelimiter(_, ":"), type text}})
in
    ETAD

EDIT
I noticed this is a MacOS so it may not work on this version 16.58
