Clipboard integration

We usually do not like to type the same twice. We also don’t like having to change from one application to another to make a specific task if this is possible from within.

With this premise in mind we developed clipboard integration a special technique and unique feature that makes it possible for foxer to be notified when a significant amount of numbers is copied to the clipboard.

Based on this technique, foxer just needs a very easy trigger: copying to the clipboard by pressing CTRL+C.

Just like magic, you get an instant conversion pop-up from where to adjust different parameters and even paste the result in the document you were working on.

Currency conversion has never been so easy!

ATC Technology

Advanced Table Conversion or ATC for short, is the special processing that helps foxer to identify dates, currencies and even bank codes when converting tables.

ATC is the key to a whole new range of features you won’t find on any other currency converter calculator:

  • To deal with multiple currency conversions in a single step.
  • Automatically load exchange rates from different dates at every single row.
  • Specify the Bank which will act as a provider.
