Text Case Counter

How to Use

Using the Text Case Counter is straightforward:

• Step 1 — Paste or type: Enter your text into the text area above. You can paste content from any source — emails, articles, code snippets, or any other text.
• Step 2 — Analyze: Click the Count button to instantly see a detailed breakdown of uppercase letters, lowercase letters, digits, spaces, special characters, and the total character count.
• Step 3 — Review results: Each category displays both the count and its percentage relative to the total letter count, helping you understand your text composition at a glance.
• Step 4 — Clear or copy: Use the Clear button to reset everything, or Copy to copy your original input text to the clipboard.

A text case counter is a specialized text analysis utility that breaks down any piece of text into its constituent character categories. Unlike a basic character counter that gives you a single total, this tool separates and counts uppercase letters (A–Z), lowercase letters (a–z), numeric digits (0–9), whitespace characters, and special characters (punctuation, symbols, and other non-alphanumeric characters).

Writers use it to verify their text composition meets specific guidelines — for instance, ensuring a headline is properly title-cased or checking that a technical document doesn't contain unexpected special characters. Developers rely on it for input validation, debugging string parsing issues, and analyzing log files. SEO professionals use it to check meta descriptions and title tags for optimal character mix.

The tool also calculates the percentage distribution of each category, giving you a quick visual understanding of your text's composition without manual counting or spreadsheet formulas.

How It Works

The Text Case Counter uses regular expression pattern matching to scan every character in your input text. Each character is classified into exactly one of six categories based on its Unicode value:

• Uppercase letters (A–Z): Characters between Unicode code points 65 and 90, inclusive. These are checked using the pattern [A-Z].
• Lowercase letters (a–z): Characters between code points 97 and 122, matched with [a-z].
• Digits (0–9): Numeric characters from code points 48 to 57, matched with [0-9].
• Spaces: Any whitespace character matched by \s, including regular spaces, tabs, and newlines.
• Special characters: Everything that doesn't fit into the above four categories — punctuation marks like commas and periods, symbols like @ and #, brackets, and any other non-alphanumeric characters.
• Total characters: The sum of all characters in your text, including line breaks and invisible whitespace.

All processing happens entirely in your browser — your text is never sent to any server, ensuring complete privacy.
