Creative Algorithm

For the time being, Pretty Formula is the only one formatter of formulas listing in the Microsoft add-in store. It is the version 2 of our previous product "Formula Formatter". Pretty Formula is innovative in the following aspects:

  1. We have created a brand-new framework to intelligently pretty-print an Excel formula. For example, a function or an arithmetic expression will no longer be formatted in the same way all the time; many factors such as width limit, its surroundings, and other parts of the formula will be taken into account.
  2. The framework is extensible such that we could easily add or remove formatting rules for a class of formulas.
  3. The editor is based on Monaco Editor, that nobody uses so far for formula displaying. Monaco Editor has many advanced features that we will leverage for formula editing, such that coloring, intellisense, auto-complete, etc.
