This is very nicely done. Personally I prefer my data entry to be a simple text field so that I can use backspace, or clipboard paste, or insert/delete from the middle normally. Meanwhile, the UI can show its interpretation of what I entered just above the field. For example, if I enter a date field 2/25, the software could show its interpretation (02/25/2019) as I type, allowing me to quit typing as soon as the interpretation is correct. Likewise with credit cards: it isn't a big problem hitting a space bar to separate, but that's my choice. In other words, the beautiful formatting is good, but keep the input field and the eventual rendering of the field separate.
