Whitespace visualizer
Invisible whitespace characters are often the culprit behind frustrating formatting inconsistencies. This tool replaces them with visible marks so you can see exactly what you are dealing with. Spaces become middle dots (·), tabs become arrows (→), and line breaks display as pilcrows (¶) right before each break — the break itself is preserved, so the content stays intact.
Use the checkboxes to toggle which whitespace types you want to see. Show spaces if you are hunting for double spaces, leading or trailing spaces that cause alignment problems, or accidental gaps between words. Show tabs if your file mixes tabs with spaces or if indentation looks wrong in different editors. Show line breaks to find unexpected carriage returns, missing breaks in pasted content, or compare how different editors handle line endings — Windows uses CRLF while Unix uses LF, a common source of issues when code is shared across platforms.
This tool is essential when debugging markup where spaces matter — HTML, CSS, code, or configuration files. It solves real problems: discovering why form submissions fail due to trailing spaces in database fields, spotting why email templates render with unwanted gaps, or finding why copied patterns don't match expected formatting. When merging text from Word documents, PDFs, or web pages, you often inherit non-breaking spaces or unusual line breaks that silently break downstream processing. The visualizer immediately reveals what your editor hides. Everything runs entirely in your browser, so your text never leaves your device.
FAQ
What do the symbols mean?
Middle dot (·) represents a space, arrow (→) represents a tab, and pilcrow (¶) represents a line break. These are the same symbols you see in most text editors when "show whitespace" is turned on.
Why would I need to see whitespace?
Whitespace problems are hard to spot with the naked eye. Trailing spaces, mixed tabs and spaces, or unexpected line breaks can break code, mess up alignment, or cause parsing errors in configuration files. Seeing them makes fixing them trivial.
Can I copy the output with the symbols in it?
Yes. The whitespace marks are part of the output, so when you copy, you get the marked version. If you need the original text back, simply toggle all marks off.
Is my text uploaded anywhere?
No. The tool runs entirely in your browser and your text never leaves your device.
Why keep the line breaks visible even with the newline mark?
The line breaks are kept so the layout is not flattened. The pilcrow appears just before each break as a marker, and then the actual break follows, preserving the original structure while still making it visible.
