Whitespace Reference
A concise reference for developer text workflows.
Whitespace is contextual
Whitespace can separate tokens, represent indentation, align text, or simply be accidental formatting.
Trim
JavaScript trim() removes recognized whitespace at both ends of a string. TinyDevTools applies it independently to each line in the Trim Whitespace tool.
Blank lines
Remove Empty Lines uses trim() only to decide whether a line has visible content. It leaves non-empty lines unchanged.
Duplicate comparison
Duplicate tools use exact line strings. Whitespace differences therefore produce different keys unless you normalize first.
