Whitespace Visualizer

Make invisible whitespace characters visible with symbolic markers.

How to Use

Paste Text

Paste text with whitespace to visualize.

See Markers

Whitespace characters are replaced with visible symbols.

Identify Issues

What Is Whitespace Visualizer?

The Whitespace Visualizer replaces invisible whitespace characters with visible symbolic markers. Spaces become · (middle dot), tabs become → (right arrow), newlines become ↵ (return symbol), carriage returns become ← (left arrow), and CRLF pairs are shown as ¶ (pilcrow). It also detects non-breaking spaces (°), zero-width spaces ([ZWS]), zero-width joiners ([ZWJ/ZWNJ]), and byte order marks ([BOM]). This tool helps debug formatting issues, find hidden characters, and understand text encoding.

Why Use Our Whitespace Visualizer?

Make invisible characters visible for debugging
Detect hidden zero-width characters
Identify line ending types (LF, CRLF, CR)
Find non-breaking spaces and BOM markers

Common Use Cases

Debugging

Find hidden whitespace characters causing formatting or parsing issues.

Code Review

Inspect whitespace in code for tab/space inconsistencies.

Data Cleaning

Identify invisible characters in data that may cause processing errors.

Typography

Check for non-breaking spaces and other special whitespace in documents.

Technical Guide

The visualizer applies a series of string replacements to convert invisible characters to visible markers. Regular spaces (U+0020) become · (middle dot). Tabs (U+0009) become → followed by the tab character. CRLF pairs (\r\n) are detected first and marked with ¶ to prevent individual CR and LF processing. Remaining newlines (\n) become ↵. Remaining carriage returns (\r) become ←. Non-breaking spaces (U+00A0) become °. Zero-width spaces (U+200B), zero-width non-joiners (U+200C), zero-width joiners (U+200D), and byte order marks (U+FEFF) are replaced with descriptive brackets.

Tips & Best Practices

1
· = space, → = tab, ↵ = newline (LF), ¶ = CRLF, ← = carriage return
2
° = non-breaking space, [ZWS] = zero-width space
3
Useful for finding invisible characters copied from web pages
4
Combine with the Zero Width Detector for detailed invisible character analysis

Frequently Asked Questions

QWhat do the symbols mean?

· = space, → = tab, ↵ = newline, ¶ = CRLF, ← = carriage return, ° = non-breaking space.

QCan it detect zero-width characters?

Yes, it detects zero-width spaces, zero-width joiners, zero-width non-joiners, and byte order marks.

QDoes it modify the original text?

The visualization is in the output only. Your input text is unchanged.

QWhat is a BOM?

A Byte Order Mark (U+FEFF) is an invisible character sometimes placed at the start of text files to indicate encoding.

QHow is this different from the Zero Width Detector?

This visualizes all whitespace types. The Zero Width Detector focuses specifically on zero-width and invisible characters.
