10 things you should never do in Excel

10 things you should never do in Excel

9 October 2017

Mastering Excel takes some experience and patience, but it's easy to make mistakes even if you've been using it for a long time. Sometimes, choices seem like a brilliant idea—until they're not, and the resulting problems are hard to troubleshoot.

In this article, I share 10 ways to avoid actions that seem good... at the time:

  • Rely on multiple links.
  • Destroy data.
  • Rely on default settings.
  • Ignore Table objects.
  • Use Excel as a database or Word processor.
  • Forget to protect your work.
  • Leave blanks.
  • Use numbers as column headings.
  • Allow error values.
  • Sluff off backups.
