Case convert, clean, count, replace, and analyze text with live updates. Type or upload a file and process content instantly.
Text Utility is a comprehensive online text manipulation and transformation tool designed to help writers, developers, and content creators work with text more efficiently. It combines essential features like case conversion, whitespace cleanup, find and replace, and real-time text statistics into a single, easy-to-use workspace. Whether you need to reformat code identifiers, clean up copied content, or analyze word counts, Text Utility handles it all directly in your browser with no sign-up required.
No. All text processing happens locally in your browser. Your content is never uploaded to or stored on any external server, ensuring complete privacy.
Yes. Simply highlight the portion of text you want to convert in the editor, then click any case conversion button. Only the selected text will be transformed while the rest remains unchanged.
You can upload plain text files including .txt, .md, .csv, .html, .css, and .js files. The content will be loaded into the editor where you can process and transform it as needed.
There is no hard limit on the amount of text you can process. Since everything runs in your browser, performance depends on your device, but the tool handles large documents smoothly in most cases.
Yes. The tool includes full undo and redo support. Use the Undo and Redo buttons in the toolbar, or press Ctrl+Z to undo and Ctrl+Y to redo changes at any time.
A text utility tool is a collection of common text manipulation operations available in one place, without writing a line of code or opening a terminal. Writers, developers, data analysts, and SEO specialists all regularly need to transform text — changing its case, counting its words, cleaning up extra whitespace, sorting lines, removing duplicates, or generating URL-friendly slugs — and doing any of these tasks manually or through a spreadsheet formula is tedious at best. A dedicated text utility tool makes these operations instant, reliable, and accessible from any browser.
For developers, text transformation is a constant background task. You copy a list of database column names in SCREAMING_SNAKE_CASE and need them in camelCase for a JavaScript object. You get a CSV dump with inconsistent capitalization in city names and need them title-cased before importing. You have a blog post title you need converted to a clean URL slug with hyphens and lowercase. All of these are two-second jobs with the right tool, and hours of regex wrangling or manual editing without it. This tool unifies those operations so you can focus on work that actually requires your judgment.
For writers and content professionals, the value is slightly different. Word counts, character counts (including or excluding spaces), sentence counts, and reading time estimates are essential for hitting editorial targets. Removing duplicate lines catches copy-paste errors in compiled research notes. Sorting lines alphabetically is invaluable when building reference lists or organizing keyword sets. The combination of developer-grade and writer-grade utilities in one interface makes this a universal workbench for anyone who works with text professionally.
Paste your text into the input box and select the "UPPERCASE" or "lowercase" transformation option. The tool applies the change instantly across the entire input, including handling Unicode characters correctly — so accented letters like é, ñ, or ü convert properly rather than breaking or getting skipped. You can also choose "Title Case" to capitalize the first letter of every word, or "Sentence case" to capitalize only the first letter of each sentence, which is useful for normalizing headings or fixing autocorrect errors that left mid-sentence words capitalized.
A slug is the URL-safe version of a text string — typically a page title or article headline converted into a short, lowercase, hyphen-separated identifier used in web addresses. For example, the title "10 Best Coffee Shops in New York!" becomes the slug 10-best-coffee-shops-in-new-york. Slug generation removes special characters and punctuation, converts spaces to hyphens, strips accents from letters, collapses multiple hyphens into one, and lowercases everything. Good slugs are concise, descriptive, and free of stop words — they help both users and search engines understand what a page is about from the URL alone.
Paste your text into the input area and the word count updates live as you type or edit. The counter splits text on whitespace boundaries, so it correctly handles multiple spaces, tabs, and line breaks without inflating the count. You'll also typically see character count (with and without spaces), sentence count, paragraph count, and an estimated reading time based on an average adult reading speed of 200–250 words per minute. These metrics are particularly useful for matching SEO content briefs, staying within social platform character limits, and ensuring ad copy fits within paid search character constraints.
Paste your list into the input field and use the "Remove Duplicate Lines" function. The tool scans each line, keeps the first occurrence, and silently discards every subsequent identical line. Most implementations offer a case-sensitive mode (where "Apple" and "apple" are treated as different) and a case-insensitive mode (where they're treated as the same). This is invaluable for deduplicating keyword lists, email address exports, log file entries, or any situation where you've merged data from multiple sources and need to guarantee uniqueness before processing or importing.
Both are conventions for writing multi-word identifiers without spaces. camelCase runs words together with each new word capitalized: getUserProfile. snake_case separates words with underscores and keeps everything lowercase: get_user_profile. JavaScript and Java conventionally use camelCase for variables and functions; Python and Ruby prefer snake_case; database column names are typically snake_case; CSS class names use kebab-case (hyphens instead of underscores). PascalCase (also called UpperCamelCase) capitalizes the first letter too and is standard for class names and React components: GetUserProfile. This tool converts between all of these formats automatically.
