Translators working on Microsoft PowerPoint® files often need to get word counts for creating estimates or invoices. While PowerPoint has a built-in statistics feature, the word count it provides is broken: it counts punctuation as words. (See below: it’s still broken as of PowerPoint 2007)
I have a free word-count program for Windows called Count Anything, which will provide word counts for PowerPoint documents, among others (Word, Excel, HTML, XML, …).
The next time you need a word count for PowerPoint, I suggest trying it out.
