What is CodeZapper
David Turner’s Codezapper:
CodeZapper is a set of Word macros that will allow you to reduce greatly the number of "slight formatting differences" in your Word documents.
"glitches" in formatting are most often created by
conversion tools that convert PDF files into editable Word files.
You can download CodeZapper from http://kilgray.com/resource-center/external-tools
Copy the .dot macro template into the default Word “Startup” folder.
Use the “CZL” button. It should be enough.
If not, use the “PDFFix” button. For spurious line breaks use “PDFTidy”
Now, use the "cleaned" document for translation in memoQ. it should show a lot less "extraneous tags".
