Convert string into array in power BI

There are a lot more elegant functions to do that but this one here is fast and nimble.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Xc5LCoAwDEXRrZSMlSZN7W9WcRel+9+GURzYN7lwCIQ3Bglt1M/LyupDcaUx77kpu8d1tfV1sjiOnsP/blZwBB/gBM7wv653YbCAYY/AHvn2qIXmvAE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Emp_ID = _t, Emp_Name = _t, Column3 = _t]),
    #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(Source, {{"Column3", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "Column3"),
    #"Added Index" = Table.AddIndexColumn(#"Split Column by Delimiter", "Index", 0, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "date_hrs_operation", each if Number.IsEven([Index]) then [Column3] & " " & #"Split Column by Delimiter"[Column3]{[Index]+1} else null),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([date_hrs_operation] <> null)),
    #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows",{"Emp_ID", "Emp_Name", "date_hrs_operation"})
in
    #"Removed Other Columns"
