About Text Case Inspector
Text Case Inspector analyses every character in your text and breaks it down by type: uppercase letters, lowercase letters, digits, symbols, and whitespace. A live colour-coded heatmap overlays each character with its category so you can spot patterns instantly. All processing happens in your browser — no uploads, no sign-up, no tracking.
