Question 1

What does this tool do?

Accepted Answer

It replaces every space character (U+0020) in your input with a hyphen-minus (-). Multiple consecutive spaces can optionally be collapsed into a single dash. Useful for creating URL slugs, filename sanitization, and command-line argument preparation.

Question 2

What is the difference between a hyphen (-) and an em dash (—)?

Accepted Answer

A hyphen-minus (-) is the standard ASCII character used in URLs, file names, and compound words. An en dash (–) is typographic, used for ranges (pages 10–20). An em dash (—) is a longer typographic dash used for emphasis. This tool uses the hyphen-minus.

Question 3

How is this different from the slug generator?

Accepted Answer

The slug generator does comprehensive URL slug conversion: lowercasing, replacing/removing special characters, collapsing spaces, trimming. Spaces-to-dashes is a simple character substitution tool with no other transformations.
