Direct Answer

The best you can do is verify file extension after know the file is a Office document (application/vnd.ms-office) and set manually the correct MIME for current file. If you have…. This is a 4-line VBA Core snippet, ranked #45th of 95 by community upvote score, from 2012.


The Problem (Q-score 7, ranked #45th of 95 in the VBA Core archive)

The scenario as originally posted in 2012

I have the following:

$mimeTypes = array('application/msword'); //used to be an array

$finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); 


$type = $finfo->file($_FILES['userfile']['tmp_name']);
$mime = substr($type, 0, strpos($type, ';'));


    if (in_array($mime, $mimeTypes)) 
      { //let it in

The problem is that I am getting “application/vnd.ms-office” as the filetype for any MSOFFICE file that I attempt to upload. I DO NOT wish to allow all MSOFFICE files, only .DOC’s. Is there a workaround for this?

**Please note that these MSOFFICE type files were created in OPENOFFICE, would this make a difference?

4-line VBA Core pattern (copy-ready)

The best you can do is verify file extension after know the file is a Office document (application/vnd.ms-office) and set manually the correct MIME for current file.

If you have access to Apache, you can add the correct MIME in conf/mime.types

application/msword doc
application/vnd.ms-excel xls
[..] etc

When to Use It — vintage (14+ years old, pre-2013)

Ranked #45th in its category — specialized fit

This pattern sits in the 92% tail relative to the top answer. Reach for it when your scenario closely matches the question title; otherwise browse the VBA Core archive for a higher-consensus alternative.

What changed between 2012 and 2026

The answer is 14 years old. The VBA Core object model has been stable across Office 2013, 2016, 2019, 2021, 365, and 2024/2026 LTSC, so the pattern still compiles. Changes that might affect you: 64-bit API declarations (use PtrSafe), blocked macros in downloaded files (Mark-of-the-Web), and the shift toward Office Scripts for web-first workflows.

Frequently Asked Questions

Is this above-median answer still worth copying?
expand_more

Answer score +10 vs the VBA Core archive median ~4; this entry is solid. The score plus 7 supporting upvotes on the question itself (+7) means the asker and 9 subsequent voters all validated the approach.

Does the 4-line snippet run as-is in Office 2026?
expand_more

Yes. The 4-line pattern compiles on Office 365, Office 2024, and Office LTSC 2026. Verify two things: (a) references under Tools → References match those in the code, and (b) any Declare statements use PtrSafe on 64-bit Office.

This answer is 14 years old. Is it still relevant in 2026?
expand_more

Published 2012, which is 14 year(s) before today’s Office 2026 build. The VBA Core object model has had no breaking changes in that window. Three things to re-test: (1) blocked macros on downloaded files (Mark-of-the-Web), (2) 64-bit API declarations (PtrSafe, LongPtr), (3) any shift toward Office Scripts for web scenarios.

Which VBA Core pattern ranks just above this one at #44?
