Microsoft has launched some new features in its Excel spreadsheet software that will boost its power. But will that only be for the benefit of users?

In its blog post about the new functionality, Microsoft says that there are “many reasons” why people might be interested in writing JavaScript custom functions, and gives the following examples:

  • Calculate math operations, like whether a number is prime.
  • Bring information from the web, like a bank account balance.
  • Stream live data, like a stock price.
