I know its late to answer, but there are a couple of methods which are still useful today, (not mentioned here).
There are two general methods.
Loop through using a VBA script with the 'Docmd.RunSQL' statement. - This is generally quite slow especially as the number of rows increases but easy to understand.
Copy your 'data array' into an excel worksheet and then use a database query link to the excel file (my preferred method) - Benefits of this is it is almost as fast as if the table was already in the database and not necessarily slowed down by the number of records as the previous method - slightly slower than the above when you have a small number of records however
The Docmd Method:
Option Compare Database
Option Base 1

vals = "" 'go through each column and copy the data to SQL string format
'replace any single quote with double quotes so it does not error importing into SQL
For j = 1 To UBound(arr, 2)
If IsDate(arr(i, j)) Then 'if a date, convert to a number and let access re-covert to date (best chance at success)
vals = vals & " cdate('" & CDbl(arr(i, j)) & "'),"
ElseIf IsNumeric(arr(i, j)) Then 'if a number put through as a number
vals = vals & arr(i, j) & ","

The Excel Link Method:
Option Compare Database
Option Base 1
'------- method created by Syed Noshahi --------

Sub ExcelLinkRoutine()
Dim arr() As Variant ' create an unsized array ready for data
Dim oExcel As Object ' Excel instance - late binding
' works with access 2007+, access 2003 has a different SQL syntax
'--------------For the purposes of the Example, put some data in the array----------
ReDim arr(5, 5)
For i = LBound(arr) To UBound(arr)
For j = LBound(arr) To UBound(arr)
arr(i, j) = i * j
If i = LBound(arr) Then arr(i, j) = "col_" & arr(i, j) 'Append "col_" before the column names
Next
Next
'----------------------------output the array to an excel file ---------------------
Set oExcel = CreateObject("Excel.Application")
oExcel.Workbooks.Add 1
Set wb = oExcel.ActiveWorkbook
'network file path & normal path examples below
'fileNameWithExtention = "\\networkpath\location\example999.xlsb" ' note that xlsb file format must be used
' other formats can be used by changing 'xlExcel12'
' ONLY change the path not the FILE NAME
fileNameWithExtention = "C:\Users\public\documents\example999.xlsb" ' same as above
checkFileExists = Dir(fileNameWithExtention)
If Len(checkFileExists) > 0 Then
'only delete the file if its called example999!
If checkFileExists = "example999.xlsb" Then
Kill fileNameWithExtention
End If
End If
With wb
.Sheets(1).Cells(1, 1).Resize(UBound(arr), UBound(arr, 2)).Value2 = arr()
.SaveAs fileNameWithExtention, 50 ' 50 means xlExcel12
.Close False
End With
Set wb = Nothing
Set oExcel = Nothing
'------------ Importing the data to a table in MS ACCESS-----------------------------
'NOTE1: The saved down excelfile MUST be named Sheet1
'NOTE2: if the file path contains special characters such as ,-'
' you may need find the correct way to input (or remove the special chars)
sSQL = "SELECT T1.* INTO [#TableTemp] " ' change table to actual table name
sSQL = sSQL & " FROM [Excel 12.0;HDR=YES;IMEX=2;ACCDB=YES;DATABASE=" & fileNameWithExtention & "].[Sheet1$] as T1;" ' linked table format
DoCmd.SetWarnings False 'turn warnings off - no popups!
DoCmd.RunSQL sSQL 'Run the SQL statement and import into the database
DoCmd.SetWarnings True 'turn warnings on
