Update Data in Closed Workbook

VBA novice here,

Is possible to update data that is queried from an external source in a closed workbook?

I use the following code to retrieve stock data from Yahoo Finance:

Sub GetData()
Dim DataSheet As Worksheet
Dim EndDate As Date
Dim StartDate As Date
Dim Symbol As String
Dim qurl As String
Dim nQuery As Name
Dim LastRow As Integer

Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.Calculation = xlCalculationAutomatic

Sheets("Data").Cells.Clear

Set DataSheet = ActiveSheet

StartDate = DataSheet.Range("startDate").Value
EndDate = DataSheet.Range("endDate").Value
Symbol = DataSheet.Range("ticker").Value
Sheets("Data").Range("a1").CurrentRegion.ClearContents

qurl = "http://ichart.finance.yahoo.com/table.csv?s=" & Symbol
qurl = qurl & "&a=" & Month(StartDate) - 1 & "&b=" & Day(StartDate) & _
"&c=" & Year(StartDate) & "&d=" & Month(EndDate) - 1 & "&e=" & _
Day(EndDate) & "&f=" & Year(EndDate) & "&g=" & Sheets("Data").Range("a1") & "&q=q&y=0&z=" & _
Symbol & "&x=.csv"

QueryQuote:
With Sheets("Data").QueryTables.Add(Connection:="URL;" & qurl, Destination:=Sheets("Data").Range("a1"))
.BackgroundQuery = True
.TablesOnlyFromHTML = False
.Refresh BackgroundQuery:=False
.SaveData = True
End With

Sheets("Data").Range("a1").CurrentRegion.TextToColumns Destination:=Sheets("Data").Range("a1"), DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, _
Semicolon:=False, Comma:=True, Space:=False, other:=False

Sheets("Data").Columns("A:Z").ColumnWidth = 12


LastRow = Sheets("Data").UsedRange.Row - 2 + Sheets("Data").UsedRange.Rows.Count
Sheets("Data").Sort.SortFields.Add Key:=Range("A2"), _
SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
With Sheets("Data").Sort
.SetRange Range("A1:G" & LastRow)
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
.SortFields.Clear
End With
End Sub

I would like to run this macro from another workbook while this workbook is closed. This is so I can then reference the values from this closed workbook in the open workbook I am working with.

I hope that all makes sense.

Thanks for taking a look!
