In the Windows Explorer it is possible to view a document’s properties. Right-click on the file and select Properties.
There is useful information in here, such as author, creation date, last saved date etc. The good news is, we can access this information using VBA with the BuiltinDocumentProperties Property.
Not all document properties are populated with data, as it depends on the file type. For example, Excel files do not have data about the number of slides property, but a PowerPoint file does. Yet, both Excel and PowerPoint files have a number of slides property, it’s just not used in all circumstances.
The basic VBA code
'Finding the author of the ActiveWorkbook Debug.Print ActiveWorkbook.BuiltinDocumentProperties("Author") 'Finding the creation date of another workbook Dim Wb As Workbook Set Wb = Workbooks("myFileTest.xlsx") Debug.Print Wb.BuiltinDocumentProperties("Creation date")
Working with closed files
By using the BuiltinDocumentProperties there is no way to read the properties from a closed file. Therefore it is necessary to open the file, read the properties, then close the file.
'Find the Last saved time of a currently closed file Dim Wb As Workbook Set Wb = Workbooks.Open("C:\Users\marks\Documents\myFileTest.xlsx") Debug.Print Wb.BuiltinDocumentProperties("Last save time") Wb.Close
Note: Take a look in the comments section below as there appears to be a way to read and change properties on a closed file. But that is outside the scope of this post.
Referencing a property which does not have any information will throw and error.
It is possible to catch the errors so that you know the value is blank:
'Catching errors when there is no value Dim fileProperty As Variant fileProperty = "Number of slides" On Error Resume Next Debug.Print ActiveWorkbook.BuiltinDocumentProperties(fileProperty) If Err.Number <> 0 Then Debug.Print fileProperty & " is blank" End If On Error GoTo 0
All the available properties
The available properties are:
Last print date

It is also possible to loop through and list all of the available properties:
'List all the file properties available Dim fileProperty As Variant For Each fileProperty In ActiveWorkbook.BuiltinDocumentProperties Debug.Print fileProperty.Name Next fileProperty
