How to use

1. 1Paste your messy text into the input area on the left. Common sources are email lists, log lines, copied code, marketing copy, and exported spreadsheets.
2. 2Pick a quick preset (Tidy text, Dedupe list, Single line, Code paste) for the most common jobs, or fine-tune any combination of options below.
3. 3For lists, set Duplicate lines to Remove duplicates (keep first) and tick Match case-insensitively if you want 'Email@x.com' and 'email@x.com' to count as the same.
4. 4Read the cleaned text on the right with live character and line counts, plus how many characters and lines were removed.
5. 5Click Copy cleaned text to copy the result, or Replace with cleaned to load it back into the input for another pass.

About this tool

Text Cleaner is an all-in-one text tidier that runs entirely in your browser. Paste any messy text on the left and a cleaned version appears on the right as you type. Each cleaning step is an independent toggle so you only run what you need: trim leading and trailing whitespace from every line, collapse runs of double or triple spaces inside a line back to a single space, replace tabs with a configurable number of spaces, strip invisible Unicode characters often pasted from rich text editors (zero-width space U+200B, zero-width joiner U+200D, zero-width non-joiner U+200C, word joiner U+2060, and the byte order mark U+FEFF), remove all blank lines, or just collapse runs of multiple blank lines into a single blank line. Duplicate-line removal supports two modes (keep the first occurrence of each line or keep the last), an optional case-insensitive match (so 'Apple' and 'apple' count as the same line), and shows a live count of duplicates detected in your input so you know what to expect. A separate option joins everything onto one line using a separator of your choice (a space, a comma, a semicolon, or any string) for cases like converting a vertical email list into a single comma-separated header. Quick presets cover the four most common jobs in a single click: Tidy text (trim plus collapse), Dedupe list (trim plus drop blanks plus dedupe), Single line (join everything with a space), and Code paste (tabs to 2 spaces, normalize line endings, leave structure intact). The pipeline order is fixed and deterministic so the same input plus same options always produces the same output, and the result panel shows how many characters and lines were removed so you can verify the cleanup at a glance. Useful for cleaning pasted email lists, deduplicating URLs and SKUs, tidying log files, prepping CSV columns, normalizing copy-pasted code, removing the invisible characters that break form validations, and stripping the trailing whitespace and excess blank lines that make text reviews painful. Everything runs locally on your device, so the lists, logs, drafts, and pasted snippets you clean here never leave your browser.
