TextSorter is a free online text cleaner offering 37 browser-based tools to clean, sort, extract, and transform text. All processing runs locally in your browser — your data never leaves your device, no account is required, and no software needs to be installed.
What Is an Online Text Cleaner?
An online text cleaner takes raw, messy text and refines it into a clean, usable format — removing extra spaces, stripping HTML, deleting duplicate entries, or reordering lines. TextSorter is a suite of 37 specialized tools for exactly this purpose. One tool per job, so you always use the right instrument rather than a generic editor.
The core design principle is privacy and speed. All text processing happens directly in your web browser using JavaScript. Your data never reaches any server. Because everything runs locally, results are instant — no waiting for a server response.
What Are TextSorter's Core Text Cleaning Tools?
Remove Duplicate Lines
The Remove Duplicates tool is essential for cleaning lists. It identifies and removes redundant entries from any list — emails, keywords, IDs, or URLs. It includes an Ignore Case option so "Apple" and "apple" count as the same item, and a Show Dupes audit mode that shows only the lines that were duplicated — useful for diagnosing redundancy without altering the original list yet.
Clean Text
The Clean Text tool removes extra spaces between words, deletes leading and trailing whitespace from each line, and eliminates unnecessary blank lines and tabs. The result is standardized, clean text ready to paste into a report, database, or another tool downstream.
Find & Replace with Regex
The Find & Replace tool supports JavaScript regular expressions, moving it well beyond a standard word replacer. You can define complex patterns to find and modify structured text — standardizing inconsistent formats, masking sensitive values like order numbers, or bulk-reformatting entries across large text files.
Strip HTML Tags
The Strip HTML Tags tool removes all markup code from pasted content, leaving only plain text. Essential for repurposing web content, preparing scraped text for analysis, or cleaning copy-pasted HTML that ended up in a document.
Keyword List Cleaner for SEO
The Keyword List Cleaner is built for digital marketers and SEO professionals. Its standout feature is near-duplicate detection — it recognizes that "best seo tools" and "seo tools best" are functionally identical by fingerprinting each phrase (sorting its words alphabetically before comparing). It also automatically strips the metadata columns (KD, Volume, CPC) from Ahrefs and SEMrush exports.
Data Extractors
TextSorter's extractors scan a block of text and pull out only the data that matches a specific pattern:
- Email Extractor — correctly handles plus addressing (
[email protected]) - URL Extractor — pulls every link from a document
- Phone Number Extractor — handles US, international, and mixed formats
- IP Extractor — pulls IPv4 addresses from logs and firewall exports
Text Diff
The Text Diff tool uses a Longest Common Subsequence (LCS) algorithm to show a side-by-side comparison, highlighting the exact characters and lines that differ between two versions of a document.
How Does TextSorter Protect Your Data Privacy?
All text processing is done client-side — when you paste text into any tool, the cleaning or transformation runs in your browser via JavaScript. Your text is never uploaded, transmitted, or stored on any external server.
This local-processing model also means the tools work without an internet connection. Once the TextSorter page has loaded, you can disconnect from the network and all 37 tools continue to work. There is no account, no signup, and no software to install.
For optional features that can interact with external services — like the Text to Speech tool, which optionally accepts your own ElevenLabs API key for premium voices — the same privacy principle applies. If you add a key, it is stored exclusively in your browser's local storage and is never transmitted to TextSorter's servers.
How Do You Clean a Keyword Export from Ahrefs or SEMrush?
- Go to the Keyword List Cleaner — no login required.
- Paste your raw keyword export directly into the input area, metadata columns and all.
- Enable "Strip Ahrefs/SEMrush metadata" to remove KD, Volume, and CPC columns.
- Enable "Remove near-duplicates" to collapse semantically identical phrases. Output updates in real time.
- Copy or download the result as a
.txtfile.
For general data cleaning: start with Remove Duplicates to eliminate identical records, then run the output through Clean Text to standardize spacing.
