Hi,
I have 15 Excel reports sourced from SharePoint.
The Source.Name column captures the report name which has the date mentioned.
Please advise how I can create a Report Date column that only captures the date from the Source.Name column so that I can hide the Source Name column before loading data for visualization.

Source.Name

If the report names are always consistent like in the sample data, this should do it. You can wrap the formula with DATEVALUE() to convert it to an actual date.

Just realized this is probably for PowerQuery. How about.

Power Query: 
= Table.AddColumn(Source, "Custom", each Text.Middle([Source.Name],47,10))

In case the beginning of the text is not always in the same length, but the date is always at the end of the string, then the following could be also used.

Power Query: 
ReportDate = Table.AddColumn(Source, "Report Date", each Text.End(Text.Select([Source.Name],{"0".."9"} & {"-"}), 10))

With sample data:
Power Query: 
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("pdI9CsJAEAbQqwxpdWVn1r/0gmCrViFFjFsEliSMKXJ8e2GE4bvAq17TVJdBc7/Q/ZZocy3Tqyv0GLIGpknfWek59iV3I2meJ11C5BDrIFHSbi2ftWq3fwjLEI9hIcmFWMreoRjEASeOOHHCiTNO1DDBESc8Rw3CU9QgPEENAt/J+E7GdzK+k/GdjO8UfKfgOwXfKb872y8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source.Name = _t]),
    // Select only numbers and dashes, then take the last 10 chars as the date.
    ReportDate = Table.AddColumn(Source, "Report Date", each Text.End(Text.Select([Source.Name],{"0".."9"} & {"-"}), 10))

Thanks, Smozgur.
There is a small cath. Here is the actual data. I had removed some portion of the source name. The file name is consistent however the spacing is a concern.
Since the date format was consistent I used "Add column from example". However, I do need a better approach to extracting the date.

Still based on some assumptions. In the following approach, I assume the is only one opening parenthesis, so I can clean the part after the date.

Power Query: 
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("vdbLCsIwEIXhVxm6UjSSSby0S2lBEBTUumnpopcIhZhI7KKPrwt9ABHOKpvABwPzM2UZZX0w7UCXvabZzvqmtpT3JggmHzoT6Opaa2pHwTx8GIRkIROhpNIkaLI9Fu8n9femd6b7/CF/I12INDtR7To65OfpYrTPMarmv3Pqy0E0DdWW2FGusNway22wXIzlEijHErkHzFBNYUepsRy2KYxtCmObwtimcAzdA2xSlMRy2DNFYaOi/rhTqhc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source.Name = _t]),
    FirstPart = Table.AddColumn(Source, "FirstPart", each Text.Start([Source.Name], Text.PositionOf([Source.Name], "("))),
    ReportDate = Table.AddColumn(FirstPart, "Report Date", each Text.Start(Text.End(Text.Select([FirstPart],{"0".."9"} & {"-"}), 11), 10))
in
    ReportDate

I think it is possible to use Regex in Power BI desktop with a custom library. In that case, it is very easy to find the date pattern.

Also, if you can pre-clean the data by using some VBA, then you can use VBScript.RegExp library to extract date data, as shown in the basic sample below.

VBA Code: 
Sub extractDate()
Dim rng As Range
Dim cll As Range
Dim rgx As Object

    Set rgx = CreateObject("VBScript.RegExp")
    With rgx
        .Pattern = "\d{1,2}\-\d{1,2}\-\d{4}"
        .Global = False
    End With

    Set rng = Selection
    For Each cll In rng.Cells
        cll.Offset(, 1).Value = rgx.Execute(cll.Value)(0)
    Next cll
End Sub

Using RegEx in PowerQuery

Power Query: 
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    RX = (x,y)=>
        let 
            Source = Web.Page(
                     "<script>var x='"&x&"';var y=new RegExp('"&y&"','g');var b=x.match(y);document.write(b);</script>")
                     [Data]{0}[Children]{0}[Children]{1}[Text]{0}
        in 
            Source,
    GetDate = Table.AddColumn(Source, "Date", each RX([Source.Name],"[0-9]{2}([\-/ \.])[0-9]{2}[\-/ \.][0-9]{4}"))

And, if you are in Power BI, you can use Python to do it like this.

Power Query: 
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("vdbLCsIwEIXhVxm6UjSSSby0S2lBEBTUumnpopcIhZhI7KKPrwt9ABHOKpvABwPzM2UZZX0w7UCXvabZzvqmtpT3JggmHzoT6Opaa2pHwTx8GIRkIROhpNIkaLI9Fu8n9femd6b7/CF/I12INDtR7To65OfpYrTPMarmv3Pqy0E0DdWW2FGusNway22wXIzlEijHErkHzFBNYUepsRy2KYxtCmObwtimcAzdA2xSlMRy2DNFYaOi/rhTqhc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source.Name = _t]),
    Python_Script = Python.Execute("dataset['Date'] = dataset['Source.Name'].str.extract(pat='([0-9]{2}-[0-9]{2}-[0-9]{4})')",[dataset=Source]),
    Expand = Table.ExpandTableColumn(Python_Script, "Value", {"Source.Name", "Date"}, {"Source.Name", "Date"})
