About the Number Formatter

This number formatter makes long numbers readable in whichever form suits the audience: thousands separators, a fixed number of decimal places, scientific notation for very large or small values, and compact notation such as 1.2M for dashboards.

A number formatter is about making a figure readable at a glance. 1234567 requires counting digits; 1,234,567 does not. Separators are the single biggest improvement you can make to any figure a person has to read.

Notation choice depends on audience. Scientific notation suits very large or very small values where magnitude matters more than digits. Compact notation — 1.2M, 3.4K — belongs in dashboards and summaries where space is short and precision is not the point.

Decimal control matters for consistency. A column where some values show two decimals and others none reads as sloppy, and fixing the decimal count is what makes tables of figures scannable.

How to use the Number Formatter

  1. Enter your number. Type the value to format.
  2. Choose the notation. Pick standard, scientific or compact.
  3. Set the decimal places. Fix the number of decimals for consistency.
  4. Copy the result. Take the formatted number.
