About Text Case & Cleaner

Text Case & Cleaner (Text Transformer) is a free, browser-based text utility that converts case, strips unwanted characters, and reorders lines, then shows live counts as you go. You paste text into the Input pane and apply one-click buttons — case conversions (UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE), cleaners (trim lines, collapse spaces, remove whitespace/blank lines/emojis/accents/punctuation), and line operations (sort A→Z or Z→A, reverse, deduplicate, shuffle) — to build the Output. Everything runs locally in your browser with plain JavaScript; nothing is uploaded and there is no signup.

How to use Text Case & Cleaner

  1. Type or paste your text into the Input pane on the left; it instantly mirrors into the Output pane.
  2. Pick a Case button (UPPERCASE, Title Case, camelCase, snake_case, CONSTANT_CASE, etc.) to convert the casing.
  3. Use Cleaners to trim lines, collapse spaces, or remove whitespace, blank lines, emojis, accents, or punctuation.
  4. Use Line operations to sort A→Z / Z→A, reverse, deduplicate, or shuffle lines — transforms chain, each applying to the current output.
  5. Check the live stats below: characters, words, sentences, lines, reading time, and bytes.
  6. Hit 'Reset from input' to start over, or copy the Output or click Download to save transformed.txt.

Frequently asked questions

Is my text uploaded to a server?
No. All transformations run entirely in your browser with local JavaScript — your text is never uploaded, stored, or sent anywhere.
Is it free and do I need an account?
Yes, it's completely free with no signup, account, or watermark.
Do the transformations stack on top of each other?
Yes. Each button applies to the current output, so transforms chain — for example you can Title Case, then trim lines, then deduplicate in sequence. Use 'Reset from input' to revert to your original text.
How does it handle case conversions like camelCase and snake_case?
It splits text into words on spaces, underscores, hyphens, dots, and slashes, and also detects camelCase and acronym boundaries — so 'hello world' or 'helloWorld' both convert cleanly to snake_case, kebab-case, PascalCase, or CONSTANT_CASE.
What exactly do the cleaners remove?
'Remove emojis' strips emoji and pictographs, 'Remove accents' converts accented letters to their plain ASCII form, and 'Remove punctuation' deletes marks like !-/ and brackets. There are also options to trim lines, collapse double spaces, remove all whitespace, and drop blank lines.
Can I save the result, and what stats does it show?
You can copy the output or download it as transformed.txt. A live readout shows characters, characters without spaces, words, sentences, lines, estimated reading time (at ~200 wpm), and byte size.
