Whitespace Counter

Whitespace is invisible until it breaks something, which is exactly why counting it is useful. Text pasted out of a PDF, a spreadsheet cell, or a Word document routinely carries non-breaking spaces, tabs, and doubled spaces that look identical to a normal space on screen. They then fail an exact-match lookup, shift a CSV column, or produce a slug with a stray separator, and the cause is genuinely hard to spot by eye.

The pattern worth watching is the ratio rather than the raw number. Ordinary English prose runs roughly one whitespace character for every five to six characters of text, because that is simply what average word length implies. A count well above that usually means doubled spaces or trailing spaces at line ends; a count well below it often means line breaks were lost somewhere in the paste and words have run together.

In practice this belongs at the start of any import routine. Normalising whitespace before you count words, generate a slug, deduplicate rows, or diff two versions removes an entire category of confusing downstream failures — two strings that render identically but compare as different. If the count here looks wrong, the remove-extra-spaces tool will clean it, and it is worth doing that pass before anything else touches the text.
