Whitespace Visualizer
Reveal hidden spaces, tabs, and line breaks in your text.
See the invisible characters
Whitespace bugs are maddening because you cannot see them: a tab where a space belongs, a trailing space breaking a match, or mixed indentation in a config file. This tool replaces spaces, tabs, and line breaks with visible markers so you can see exactly what is in your text.
It is the fast way to diagnose why two strings that look identical will not match, or why a YAML or Python file complains about indentation.
What it shows and privacy
It marks each kind of whitespace distinctly so you can tell a tab from a run of spaces, then copy your cleaned text back out. All processing runs in your browser, so config files and snippets are never uploaded.
