Tooloogle's text converters are built for anyone who works with words: writers, developers, marketers, students, translators, content moderators, and SEO specialists. Paste any block of text and reshape it into the format you need — change case, generate slugs, count words and characters, sort lines alphabetically, remove duplicates, transliterate accents, or transform punctuation. Each tool does one thing exceptionally well.
Switch between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, and even random "sPoNgEbOb cAsE". Useful for code naming conventions, data normalisation, headline formatting, and meme generation.
Convert any title or phrase into a clean, URL-safe slug. Handles diacritics (café → cafe), removes punctuation, collapses whitespace into hyphens, and supports custom separators. Essential for blog post URLs, SEO-friendly file names, and database identifiers.
Get instant counts of characters (with and without spaces), words, sentences, paragraphs, lines, and reading time. Compare against limits for tweets, SMS, meta descriptions, and academic essays. Includes Unicode-aware counting so emoji and CJK characters are tallied correctly.
Plain-text and regex-powered find-and-replace across multi-line input. Preview matches before applying. Supports capture groups, case-insensitive matching, and whole-word boundaries.
Sort lines alphabetically (A→Z, Z→A), numerically, by length, or naturally (so "file2" comes before "file10"). Remove duplicate lines, trim trailing whitespace, randomise line order, and reverse line order — all in seconds.
Reverse word order, character order, or line order. Generate upside-down text using Unicode lookalike characters. Useful for puzzles, fun social-media bios, and accessibility testing.
Strip leading/trailing whitespace, collapse multiple spaces into one, remove blank lines, normalise line endings (LF/CRLF/CR), and convert tabs to spaces (and back). Essential for cleaning copy-pasted content from PDFs, emails, and scraped pages.
Convert straight quotes (" ') to curly typographic quotes (“ ‘) and back. Replace em-dashes, en-dashes, and ellipses with ASCII equivalents. Strip or normalise punctuation for text analysis.
Convert accented Latin (é, ñ, ü) to plain ASCII (e, n, u). Romanise Cyrillic, Greek, Hindi (Devanagari), Japanese (kana), and Korean (Hangul) for cross-script searching, file naming, and database storage.
Convert numbers to words (1234 → "one thousand two hundred thirty-four") and words to numbers. Format numbers with thousand separators, decimal places, and locale-specific styles (1,000.50 vs 1.000,50).
Text formatting issues cost real time. A 10,000-line CSV with mixed-case headers needs normalising before import. A blog draft pasted from Word arrives with curly quotes and non-breaking spaces that break code blocks. A list of email subscribers contains duplicates and trailing whitespace that inflates your bill. A title needs a clean slug for the URL and a different format for the meta tag. Without quick converters, each of these tasks would take a custom script or a half-hour of manual editing.
Most converters handle hundreds of thousands of lines without freezing the browser. Paste an entire log file or export, run the conversion, copy the result, and paste it where you need it. No size limits, no timeouts, no signup.
Every transformation runs in JavaScript locally. Your text — which often contains real customer data, draft articles, or internal notes — never leaves your browser. Verify with DevTools that no network request fires when you click "Convert".
Bloggers and SEO specialists slugify titles and clean meta descriptions. Developers normalise variable names and clean test fixtures. Data analysts dedupe lists before import. Translators transliterate names for international databases. Marketers count tweet length and clean copy from designers. Students format citations and reformat papers. Email marketers clean subscriber lists. Customer-support teams sort and dedupe ticket exports.
For SEO slugs, always preview the URL after conversion — some CMSs add their own normalisation, which can produce surprising results. When deduping, decide whether case-sensitivity matters (Email vs email). For sorting, "natural" sort beats alphabetic sort for filenames and version strings. When pasting from Word, run the whitespace cleaner first to get rid of invisible characters. Always count meta descriptions in characters, not words — search engines truncate by character.
