Import excel data to existing pdf form

I am trying to autofill an existing PDF from excel table. Overall i have figured out the vba design however currently stuck at how to populate date fields where it only accepts data as Y Y Y Y M M D D meaning each digit is individually typed. In excel i have the date as 20201225 however the vba is unable to copy paste that into the date field.

How can i parse the date field in excel to allow the form to be populated? 

For example i want date value from Col A to first date field in the form and Value from Col B to Second date field.

The macro is unable to copy paste data for this field:

Application.SendKeys "{Tab}", True
Application.SendKeys datenominee, True
Application.Wait Now + 0.000005

Sub createpdfforms()
Dim pdftemplatefile, newpdfname, savepdffolder, datenominee, dateend As String

Dim custrow, lastrow As Long
With Sheet1
lastrow = .Range("A2000").End(xlUp).Row
pdftemplatefile = .Range("D3").Value
savepdffolder = .Range("D5").Value


Application.Wait Now + 0.00002

For custrow = 8 To 8
datenominee = .Range("A" & custrow).Value
dateend = .Range("B" & custrow).Value
Application.SendKeys "{Tab}", True
Application.SendKeys datenominee, True
Application.Wait Now + 0.000005


Application.SendKeys "{Tab}", True
Application.SendKeys .Range("B" & custrow).Value, True


'so forth and so on for all fields


Next custrow
End With
End Sub
