Is my text sent to the server?

No. All processing runs locally in the browser and content is not stored in a database, cookies or local storage.

Can I clean text copied from a PDF?

Yes. The PDF preset applies conservative cleanup for spaces, tabs, blank lines and simple wrapped lines; every option can be changed before processing.

How are duplicate lines removed?

The first occurrence is preserved. Comparison ignores case by default and can optionally be case-sensitive or ignore accents without changing the kept text.

Can deduplication distinguish case and accents?

Yes. Case-insensitive comparison is the default; Ignore accents can treat forms such as café and cafe as equivalent.

Does capitalization correct proper names?

No. Sentence case, Capitalize Words and Simple Title Case are mechanical transformations, not linguistic or editorial correction.

Does it detect every valid email and URL?

No. It uses practical patterns for common emails and URLs beginning with http://, https:// or www., so some technically valid formats may not be covered.

Can I download the result?

Yes. TXT is available in all modes and CSV/JSON in lists and extraction. Files are generated locally in the browser.

What is the maximum text size?

The hard limit is 1,000,000 characters. A large-text warning appears from 200,000 characters and input is never silently truncated.

Online text cleaner: spaces, case and lists

Paste text to clean it, change case, prepare lists, or extract emails and URLs without sending it to a server. You can combine cleanup, case transformations, deduplication, natural sorting, numbering, and line splitting/joining. Original input and result stay separate, and the original is held only in this tab’s memory so it can be restored.

Mode options

Operations always run in the same order so the same input and options produce the same result.

Conservative PDF presetEnables spaces, tabs, blank-line cleanup and conservative joining of simple line breaks. Normalize line endingsConverts CRLF and CR to LF. Remove invisible charactersRemoves zero-width characters, internal BOM and soft hyphen. Tabs to spacesConverts each tab to a space before repeated spaces are collapsed. Trim each lineRemoves leading and trailing spaces from each line. Collapse repeated spacesReduces horizontal space sequences to one space. Remove empty linesRemoves all empty lines from the result. Limit consecutive blank linesKeeps at most one blank line between blocks. Conservatively join simple line breaksRespects paragraphs, terminal punctuation, lists and short lines that may be headings. Remove accents/diacriticsUnicode NFD → remove marks → NFC; this is not spell checking.

TXT is available in all four modes; CSV and JSON are enabled for Lines and lists and Extract. Everything is generated locally and filenames never contain user text. If text, mode or options change, the previous result remains visible as outdated and actions stay disabled until you process again.

How cleaning, case, lists and extraction work

The cleaning pipeline has a fixed order: line endings → invisible characters → tabs → line trimming → repeated spaces → blank lines → conservative line joining → diacritics. Change case applies one case transformation first and optionally removes diacritics afterwards.

Lines and lists can split separators into entries, trim, remove empty entries and duplicates, sort with Intl.Collator, reverse, number and join again. Deduplication always preserves the first occurrence.

Extract finds common email addresses or URLs with protocol/www. Email duplicates are compared case-insensitively; URLs use exact comparison. Clearly external trailing punctuation is removed without opening links.

Conservative line joining avoids joining after sentence endings, list items, paragraph boundaries or short heading-like lines. It is a heuristic and cannot perfectly reconstruct every PDF.

Privacy and limits

Pasted content is never sent to PHP, endpoints, AI, analytics, logs, cookies or local storage. Original and latest result exist only in memory while the page is open. The hard limit is 1,000,000 characters and a large-text warning starts at 200,000. Case transformations are mechanical and email/URL regexes are practical patterns, not universal validators.
