A practical text workbench
Paste notes, copied lists or rough drafts. Change letter case, remove repeated lines, normalize spacing and export the result without creating an account. Everything runs in your browser.
TRANSFORM
Built for everyday text
Each button applies a single, predictable change and writes the result to the output panel. The input is never modified, so you can try a transformation and compare it against the original before you commit. Every rule is documented in How it works.
Convert headings, labels and sentences without retyping every word. Sentence case preserves the flow of ordinary writing; Title Case makes headings easier to scan. The exact rules are set out in the case conversion guide.
Sort lines alphabetically, reverse their order or remove exact duplicates while keeping the first occurrence. Blank lines can be removed separately. See the sort versus reverse guide before you reorder anything that has a sequence.
Clean spacing trims each line and collapses repeated spaces and tabs without changing the words themselves. For pasted PDFs and emails, follow the pasted-text guide.
Transformations run in the browser. Text Tidy requires no account and does not send the contents of the editor to an application database. See the privacy policy for the full picture.
No. There is no account and no document library. Every transformation runs in your browser with JavaScript, and the contents of the editor are not sent to an application database. Your browser, any extensions you have installed, your network administrator or your device may keep their own logs, which is outside our control.
Spacing cleanup, sorting, duplicate removal, counting and line reversal work with Unicode text. Letter-case behaviour depends on the rules supported by your browser and does nothing for scripts that have no upper and lower case, such as Chinese, Japanese, Arabic or Hebrew.
Two lines are duplicates when their trimmed text matches exactly. The first matching line is kept in its original position and later copies are removed. Case and internal spacing differences are not treated as equal, so “Apple” and “apple” both survive.
Because no automatic rule knows your style guide, your brand names or your acronyms. Short words, names, initialisms and specialist terms follow different conventions, and the converter provides a consistent starting point rather than an editorial decision.
There is no imposed limit. The work happens in your browser, so very large inputs are bounded by your device's memory and by how responsive the editor remains. Lists of tens of thousands of lines are handled without trouble.
