Power Query:
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", Int64.Type}}),
    #"Split Column by Position" = Table.SplitColumn(Table.TransformColumnTypes(#"Changed Type", {{"Date", type text}}, "en-US"), "Date", Splitter.SplitTextByPositions({0, 4}, true), {"Date.1", "Date.2"}),
    #"Split Column by Position1" = Table.SplitColumn(Table.TransformColumnTypes(#"Split Column by Position", {{"Date.1", type text}}, "en-US"), "Date.1", Splitter.SplitTextByPositions({0, 2}, true), {"Date.1.1", "Date.1.2"}),
    #"Merged Columns" = Table.CombineColumns(#"Split Column by Position1",{"Date.1.1", "Date.1.2", "Date.2"},Combiner.CombineTextByDelimiter("/", QuoteStyle.None),"New Date"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Merged Columns",{{"New Date", type date}})
in
    #"Changed Type1"

This example placed the date (text) was in Column A

My approach would be adding a custom column with the following line of code.

#date(Number.FromText(Text.End([Day],4)),Number.FromText(Text.Start([Day],2)),Number.FromText(Text.Middle([Day],2,2)))

Add column > custom column> then "[Day]" which should be replaced by your column name pointing to the date in text format.

Wow, worked great!!!. Thanks. I am new to PowerQuery and have made great progress but get stuck every once in a while.

I do have another question after trying to solve it, but have been unsuccessful. I am importing a column that is formatted as General in the Orginal file. The data in each column contains records that are all different make-ups: 8 digits (45432689), multiple digits with characters(45R4367), and digits with characters and symbols (R-789876). When I "Close and Load" to the data file, I get an error. I am OK with formatting as Text, but still, get errors. Any ideas?

(The custom column might be returning errors. Make sure that the result is returning no errors.)
Formula above is on an assumption that your text is formatted in MMDDYYYY so it is splitting it into #date(YYYY,MM,DD) you might need to switch the formulas.

*Also maybe you need to set the custom column to your local date.

Click the left most part of your custom column and click "Using Locale..."
Then set it in a way in such that your column date is similar to the custom column.

just a guess tho.
