Say it naturally.
Get it written properly.

Numbers that know they are a series

Say a list of numbered items the way you say it out loud and it comes out numbered properly, with the decimal part carried down the list. Ranges keep their unit on both ends.

Part numbers, UPCs and phone numbers

These are the ones that cost you the most time, because a wrong digit is invisible until something ships to the wrong place. You set up a template once, give it a spoken trigger, and the digits land in the right shape every time.

Dates, in your format

Three formats to choose from, and you decide whether the words you used to introduce the date stay in the sentence or drop out. Several dates in one sentence are handled separately.

Times, money and arithmetic

Times follow your Windows clock, 12-hour or 24-hour. Money comes out as money. Arithmetic comes out as something you can paste into a calculator or a spreadsheet note.

And the ones that are just annoying

Addresses are the clearest example. No dictation tool hears the word correctly, because the two words sound identical.

Can I choose the date format?

Yes. Three formats, and a separate switch for whether the words that introduced the date stay in the sentence.

Does it change numbers I don’t want changed?

Formatting only fires on a clear signal: a trigger phrase you chose, the word “dollars”, or a number on both sides of “times”. Each kind has its own switch, so anything you don’t want is one checkbox away from off.

What if I dictate into a spreadsheet?

The same rules apply, which is usually the point. A number that arrives already formatted is a number you don’t have to re-key.
