What is Whitespace Visualizer?

Whitespace Visualizer makes invisible characters visible in your text. Spaces, tabs, newlines, carriage returns, non-breaking spaces, and zero-width characters are each displayed with distinct visual markers — essential for debugging formatting issues, comparing indentation styles, or cleaning data files.

How to use

1. Step 1 — Paste or type text into the input area. Whitespace characters are immediately highlighted with color-coded markers.
2. Step 2 — Toggle which whitespace types to highlight: spaces, tabs, newlines, carriage returns, non-breaking spaces, and zero-width characters.
3. Step 3 — Review the character statistics showing counts of each whitespace type, and copy the annotated text if needed.

Result

A CSV file fails to parse. Paste a few lines into the visualizer to discover tabs mixed with spaces as delimiters, plus a hidden zero-width space in the header row causing the first column name to mismatch.
