This site, and what you can do on it

Excel-Tutorial.com is his own site. It is not only a collection of articles: it is a place to practise.

The Excel exercises run in your browser. A real grid, a real formula to write, and an immediate correction that tells you what went wrong. Nothing to download, and nothing to break on your own files.

The premium quizzes go one step further: you answer, and you receive a written review of what you already master and what to work on next. Useful when you need to prove your level, or simply to know where you stand.

StyleCleaner, a Word add-in he designed and built

Frédéric LE GUEN does not only use Office, but he also develops for it. StyleCleaner is a Word add-in he designed and developed himself.

It converts the manual formatting of a document into the real Word styles that the document should have been using. It analyses the file, rebuilds the styles, and clears what is left behind. Everything happens on your own computer: no document ever leaves it.
