Text Cleaner
A text cleaner built as a visible pipeline. Switch on the operations you need — trim, collapse spaces, remove blank or duplicate lines, sort, strip HTML or accents, wrap, number, prefix, join or find and replace with regex — and watch them apply in order with a full before/after summary.
How to use Text Cleaner
- Paste the messy text, or press “Load sample text” to see the pipeline in action.
- Switch on the operations you want. They are numbered and always run in that order, so the result is predictable.
- Set the options for each step — sort direction, duplicate case sensitivity, wrap width, prefix and suffix, or a find-and-replace pattern.
- Read the change summary to confirm exactly how many lines and characters were removed, then copy or download the cleaned text.
About Text Cleaner
Text arrives from the real world in a state: a column copied out of a spreadsheet with trailing spaces, an email list pasted from a thread with duplicates and blank lines, an article grabbed from a web page and dragging half a stylesheet of tags behind it. Doing that tidy-up by hand in a text editor is slow and easy to get wrong. Doing it with a chain of small, visible operations is fast, repeatable and — importantly — reversible, because your original text stays untouched in the input pane.
The design decision that matters here is the fixed, visible order. Tools that apply operations in whatever order you click them produce results nobody can reproduce. Here the pipeline is numbered on screen and always runs the same way: markup removal first, then substitution, then whitespace normalisation, then line-level filtering, then sorting, then decoration and layout. Trimming happens before blank-line removal so that lines containing only spaces are actually caught, and duplicate removal happens before sorting so the kept order is meaningful.
Every run finishes with a change summary — lines in, lines out, blanks removed, duplicates removed, characters saved — so you can verify the clean did what you expected rather than trusting it. Find and replace supports both plain text and full regular expressions with a safe-compile guard: a half-typed pattern such as ( shows a clear error instead of throwing, and the last valid output stays on screen while you finish typing.
Frequently asked questions
Is the text cleaner free and private?
Yes on both counts. There is no sign-up and no size limit beyond your device, and every operation runs locally in your browser — your text is never uploaded.
In what order are the operations applied?
Exactly the order shown on screen, top to bottom: strip HTML, find and replace, trim, collapse spaces, strip accents, remove empty lines, remove duplicates, sort, add prefix and suffix, wrap, number lines, then join. Order matters — trimming before removing blank lines catches lines that only contain spaces.
Does removing duplicate lines keep the first or the last copy?
The first occurrence is kept and every later repeat is discarded, so the original order of the surviving lines is preserved. A case-sensitivity switch lets you decide whether “Apple” and “apple” count as the same line.
What is natural sort and when should I use it?
Natural sort compares embedded numbers numerically rather than as text, so item2 comes before item10 instead of after it. Use it for filenames, version strings, chapter lists and anything else where numbers are part of the label.
Can I use a regular expression in find and replace?
Yes. Tick regex mode and the pattern is compiled with the global flag, so \s{2,} or ^\d+\.\s* work as you would expect and $1 back-references are available in the replacement. Invalid patterns are caught and reported instead of breaking the page.
Is stripping HTML tags safe for pasted web content?
Yes — tags are removed with a text-level parser and common HTML entities are decoded back to characters. Nothing from your input is ever executed or rendered as markup, so pasted scripts are treated as inert text.
