Eliminate clutter in Microsoft Word generated HTML files with the Office 2000 HTML Filter

Learn how to eliminate the extra HTML tags generated by Word 2000

Although you can create clean HTML code to produce content for a Web site using just about any text editor, Microsoft Word doesn't do a very good job of producing efficient HTML. On the other hand, Word is very good for collaboration and is just about as universally accepted for document creation as the pen.

So what do you do if you want to create clean HTML but don't want to abandon Word and the useful things it does bring to the table? You can use Microsoft's Office HTML Filter to remove the extra tags that Word generates and create squeaky-clean HTML documents.

What's wrong with Word?

Microsoft Word does a great job as a word processor, but it's not very useful for creating HTML documents that you can quickly plug into a Web site. When you a Word document as HTML, Word adds page- formatting tags that can make the document very large. These page-formatting tags may also cause content management programs and Web sites to behave unexpectedly.

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

Unfortunately, when you then move a standard Word-generated HTML file to a Web site, bad things can sometimes happen. Formatting tags included in the Word file can conflict with settings on a Web server, causing the document to display incorrectly. Additionally, a browser may misinterpret the tags and display the file incorrectly. The HTML file also contains versioning and authoring information that you may not want to have appearing on a Web site.

To save a Word document in HTML, select Save As Web Page from the file menu. Using this article as an example, Figure A shows the clutter that Word adds to an HTML document.

Microsoft Word adds its own formatting information to HTML files.

Basically, the first 100 lines of the HTML file contained nothing but formatting information. Actual information didn't appear until line 93 of the file. This complete article, saved in Microsoft Word's default HTML format, consumed 18 KB of space. As you can see, it's both large and inefficient.

Obtaining and using the filter

Both Microsoft Word 2002 and Word 2002/XP include an option to save Filtered HTML, but the filtered versions still include a lot of clutter. Word 2000 doesn't include a Filtered HTML option at all. That's where the Office 2000 HTML Filter 2.0 comes in. This is a freeware utility that you can download from Microsoft's Download Center that will strip the excess formatting tags from Word-generated HTML files.

The file you'll download, msohtmf2.exe, is small (only 256 KB), so it will download very quickly. Save the file to a temporary location on your workstation. You'll install the filter using this file.

When you start the installation, you'll notice that it installs just like any other Windows program you've ever installed. There are no gotchas along the way; just follow the on-screen prompts.

After the installation is done, you can use the filter. Begin by restarting Microsoft Word. In the File menu, you'll now notice CompactHTML in the Export To menu choice. Open a Word document and save the file by clicking File | Export To | Compact HTML. When the Export To HTML As window appears, give the document a file name and click Save.

As you can see in Figure B, the resulting HTML code is somewhat cleaner. Also, the file size is reduced dramatically. Using the CompactHTML feature, the file size for this document went from 18 KB to 12 KB.

The CompactHTML settings create cleaner HTML code.

Cleaning things up even more

Even though CompactHTML is an improvement, you can strip even more information out of the document by using the Office 2000 HTML Filter's actual utility. To start it, click Start | Programs | Microsoft Office Tools | Microsoft Office HTML Filter 2.0. When you do, you'll see the utility window shown in Figure C.

You can create cleaner code by using the filter interactively.

The filter is very easy to use. Click Add, select the file you want to convert, and click Apply. You can convert multiple files by continually clicking Add and adding files before clicking Apply.

By default, the filter doesn't clean the HTML any better than the CompactHTML settings in Word do. However, you can customize the filter by clicking the Options button. When you do, you'll see the screen shown in Figure D.

You can control filter settings.

Options you can control here include:

  • Delete Backups After Processing - The filter creates a backup copy of your file before conversion that you can revert to in case the conversion is not to your satisfaction. Selecting this checkbox eliminates the original.
  • Delete Non-Essential Linked Files - Selecting this checkbox removes any references to linked files in the document.
  • Remove Microsoft Office Native Markup - You can select this checkbox to remove all of the Word-related tags from the document.
  • Remove LANG Attributes - If you select this checkbox, the filter removes all language related tags such as <body lang=EN-US>.
  • Remove Non-Essential META Tags - Selecting this switch removes meta tag information that could confuse search engines, such as the name of the program you used to create the document.
  • Use VML For Displaying Graphics - This switch removes static images in the document.
  • Remove Standard CSS - This switch removes any Cascading Style Sheet information.
  • Remove All STYLE Elements - If you select this switch, then the filter will remove all STYLE references that are used by Cascading Style Sheets.
  • Remove Standard @Rule Constructs - This checkbox controls whether or not the document will include @rule definitions such as @font-face.

I've found the best results by selecting all of the checkboxes except for Delete Backups After Processing and Use VML For Displaying Graphics. You should experiment to see which settings work best for your situation. Using these settings, the filter produced the HTML for this article as shown in Figure E.

Here's how the filter created HTML for this article.

As you can see, the HTML is much cleaner. It's smaller too: The final converted article is only 10 KB in size.

Who needs a GUI?

The Office 2000 HTML Filter also allows you to convert files from the command line as well as from the GUI. To use it, open a command prompt. You'll use the filter command to filter your HTML files.

You don't need to worry about knowing where Filter is located. During Setup, the Office 2000 HTML Filter setup program installs Filter.exe to the \Windows directory so it's already in your path.

To convert a file, type filter file1.htm file2.htm and press [Enter], where file1 is the name of the source file and file2 is the name of the target filtered file. Filter includes switches that you can use to control just how much information is removed from the source file. To get a complete list of switches and how to use them, type filter /? and press [Enter].

Office 2000 HTML Filter caveats

Don't let the Office 2000 in the title discourage you if you use Word XP. The Office 2000 HTML Filter 2.0 works just as well with Word XP generated HTML as it does Word 2000 HTML. The problem is that the installer for the Office 2000 HTML Filter won't allow the program to install unless you have Office 2000 on your system.

You can get around the limitation by first installing the filter on a computer that already has Office 2000 on it. Then, copy these files from the Office 2000 workstation to your workstation:

  • MSFilter.exe
  • MSFilter.dll
  • Filter.exe

The DLL file is best placed in your C:\Windows\System32 directory, but you can also place all of the files into an OfficeFilter directory. Just create a shortcut to the MSFilter.exe file and you're ready to go.
