Sort My List (sortmylist.com) is a browser-based list sorting and cleanup tool that alphabetizes, reorders, deduplicates, and reformats pasted text. You paste a list, choose an operation, and copy or download the result. According to the site, all processing happens in your browser and your list is never uploaded, so it suits contact lists, guest lists, email exports, and other text you'd rather not send to a server. It has been available since 2008.

What the tool is for

The site positions itself as a single-purpose editor: "Paste it below and pick what to do." Each operation is also exposed as a separate tool page with examples, and the site says your list follows you from tool to tool while staying in your browser. That makes it a practical fit when you have a messy block of text and need a clean, ordered version without opening a spreadsheet.

Core sorting options

The editor groups sorting actions by data type:

The last-name sort is the one most people miss in a plain text editor: it reorders "Smith, John"-style entries correctly, and the title option keeps entries like "The Great Gatsby" filed under G rather than T.

Cleanup and formatting

Beyond ordering, the tool handles the cleanup work that usually precedes sorting:

• Duplicates: remove duplicate lines, or use the email-specific tools to clean an email list, extract addresses from text, or remove one list from another (for unsubscribes and bounces).
• Line breaks: remove all line breaks, or remove them while keeping paragraphs.
• Spaces and characters: trim spaces from each item, remove extra whitespace, strip punctuation and symbols.
• Item edits: swap word order ("Smith, John" → "John, Smith"), mirror text, change case (lower, UPPER, Title, Sentence, first letter, random), and add numbering or labels before or after items.
• Find and replace: replace text with or without case sensitivity, and cut each item at a given string (delete before or after it).

How to use it

1. Paste your list into the editor. The tool auto-detects how items are separated (new lines, blank lines, commas, semicolons, tabs, spaces, pipes), and you can override that choice.
2. Pick an operation — for example, Alphabetize A → Z, By last name, or Remove duplicates.
3. Choose how results should be separated (same as now, new lines, commas, and so on).
4. Copy the result, download it as a .txt file, or print it. Undo and redo are available if a step goes wrong.

You can also open an existing text file instead of pasting.

Privacy and cost

The site states that everything happens in your browser and your list is never uploaded — the main reason to prefer it over a web service that processes lists server-side. It describes itself as free since 2008. The page mentions "subscribe" among its signals but provides no pricing details, so treat the free claim as the site's own description rather than a verified tier structure.

When it's a good fit — and when it isn't

Use Sort My List when you have plain text to order or clean: a guest list, a column copied out of a spreadsheet, an email export, or a list with inconsistent spacing and duplicates. The email tools (fixing typos, dropping bad or throwaway addresses, finding near matches like jon.smith@ vs. jonsmith@, merging CSV exports) cover contact-list maintenance that would otherwise need a spreadsheet or script.

It is not a spreadsheet: there are no formulas, columns of mixed data types, or persistent files. For large structured datasets or repeatable pipelines, a spreadsheet or script will serve you better. For one-off text cleanup where privacy matters, it's a direct fit.

Paste your list into the editor on sortmylist.com, choose how the items are separated, then pick a sort or cleanup action from the menus. The result appears in the same editor, where you can copy, download, or print it. Everything runs in your browser, so the list is never uploaded.

Before you start

• What you need: a list in plain text, such as names, emails, addresses, or numbers.
• What you don't need: an account or a file upload. The site describes itself as free since 2008 and says lists stay in the browser.
• One thing to check: the site's materials mention a "subscribe" keyword but give no pricing details, so don't assume any paid tier or login requirement either way.

Step 1: Paste the list and set the separator

Paste your items into the editor. Then use the Items are separated by control to tell the tool how your list is divided. Options include:

• New lines
• Blank lines
• Commas or comma + space
• Semicolons or semicolon + space
• Tabs
• Spaces
• Pipes ( | )
• Something else (auto-detected)

If your paste looks like one giant block, the separator is usually the culprit. Switch from "New lines" to commas, or the reverse, and the items should split correctly.

Step 2: Choose a sort or cleanup action

The editor groups actions into menus. Pick the one that matches your goal.

Sorting

Cleaning up

• Duplicates: Remove duplicates, or use the email-specific cleanups (fix typos and bad addresses, extract addresses from text).
• Line breaks: Remove all line breaks, or remove line breaks while keeping paragraphs.
• Spaces & characters: Trim spaces from each item, remove extra whitespace, remove punctuation & symbols.
• Items: Swap word order ("Smith, John" → "John, Smith") or mirror each item's text.
• Case: lower case, UPPER CASE, Title Case, Sentence case, capitalize first letter, or rAnDoM cAsE.
• Numbering & labels: Add a number or label between the label and the item, in formats like 1. item, A. item, length. item, or item.
• Cut & replace: Find and replace (with an option to ignore capitalization; type \n for a new line), or cut each item at some text and delete before or after it.

Step 3: Check the result and export

The sorted or cleaned list replaces the content in the editor, so review it before you leave the page. Then use:

• Copy to clipboard or Copy to paste it elsewhere
• Download as .txt to save a file
• Print for a paper copy
• Undo / Redo if an action wasn't what you wanted
• Clear to start over

You can also adjust the Output separator (same as now, new lines, commas, semicolons, tabs, spaces, pipes, or something else) so the result matches where it's going next.

Working across multiple tools

Sort My List splits some jobs onto dedicated pages under All list tools, such as cleaning an email list, extracting email addresses from messy text, sorting emails by domain, removing one list from another, finding near matches like jon.smith@ versus jonsmith@, and merging CSV files. The site states that your list follows you from tool to tool and stays in the browser the whole time, so you can sort on one page and clean up on another without re-pasting.

Common snags

• Nothing splits into items: change the separator setting; auto-detect doesn't always guess right.
• Sort order looks wrong: check whether stray spaces or punctuation are being counted. Trim spaces or remove punctuation first, then sort.
• Names sort by first name: switch to By last name, or use Swap word order if your list is formatted "Last, First."
• Titles land under "T" or "A": use the titles option that ignores "The," "A," and "An."
• A cleanup removed too much: use Undo, or run the cleanup on a copy of the list.

Sort My List handles email addresses with two separate tools: one cleans an existing email list (fixing typos, dropping bad, duplicate and throwaway addresses), and one extracts every address out of messy text. Related tools sort emails by domain, remove one list from another, and find near matches. All processing happens in your browser — the site states your list is never uploaded.

What each email tool does

How to clean an email list

1. Open the "Clean an email list" tool from the All list tools page.
2. Paste your addresses into the editor. The tool auto-detects how items are separated, or you can set the separator yourself (new lines, commas, semicolons, tabs, spaces, pipes).
3. Run the clean action. Expected result: typos corrected, and bad, duplicate and throwaway addresses dropped.
4. Review the output, then copy it to the clipboard or download it as a .txt file.

Verification: check that the count of addresses went down only by the number you expected to lose, and spot-check a few corrected entries.

Common snag: if your list uses an unusual separator (for example, addresses pasted from a spreadsheet with trailing tabs), set the separator manually rather than trusting auto-detection.

How to extract email addresses from text

1. Open "Extract email addresses."
2. Paste the messy text — email bodies, signatures, documents — into the editor.
3. Run the extraction. Expected result: a clean list containing only the addresses found in the text.
4. Choose your output separator (same options as input) and copy or download.

This is the tool to reach for when addresses are embedded in prose rather than already listed one per line.

Sorting and de-duplicating by domain

To group addresses by company or provider, use "Sort emails by domain." To catch duplicates that differ only slightly, run "Find near matches" — it surfaces pairs like jon.smith@ and jonsmith@ so you can decide which to keep. For a mailing list with unsubscribes or bounces, "Remove one list from another" subtracts the suppression list from your send list.

Practical notes

• The editor also offers general cleanup that applies to any list, including email lists: trim spaces, remove extra whitespace, remove punctuation and symbols, change case, and find and replace.
• Undo and redo are available, so you can test a cleanup step and reverse it.
• Your list follows you from tool to tool within the browser session, and it stays in your browser the whole time.
• The site describes itself as free since 2008; the page shows an advertisement, and a "subscribe" signal appears in the site data, so treat any premium features as something to check on the site rather than assume.

If your goal is simply to alphabetize names rather than process addresses, the same editor's sort options (A → Z, by last name, and so on) cover that on the main Sort My List page.

To sort a name list by last name, paste your names into the Sort My List editor and choose By last name under the Sort options. The tool runs entirely in your browser, so the list is never uploaded. This works best when each name is on its own line and written in first-name-first order (for example, “John Smith”). If your names are stored as “Smith, John,” use the Swap word order cleanup option first so the last name ends up in the right position.

Sort by last name: what the option does

The By last name sort treats the final word in each item as the surname and orders the list alphabetically by that word. It is designed for ordinary personal names, so it fits guest lists, class rosters, and contact lists where each entry is a single person’s name.

The editor’s example list shows the intended input format:

Dr. Ann Baker
Tom Zimmerman
Mary O'Neil
Carl Adams
Lisa Ray

With By last name selected, these are ordered by Baker, Zimmerman, O'Neil, Adams, and Ray rather than by first name.

Check your separators first

Sorting only works correctly when the tool recognizes where one name ends and the next begins. Use the Items are separated by control to match how your list is formatted:

• New lines — the safest choice for a pasted list with one name per line.
• Commas or Comma + space — for lists typed as a single run of text.
• Semicolons, Tabs, Spaces, or Pipes ( | ) — for exports from spreadsheets or other tools.
• Something else… — lets you define a custom separator.

The tool also offers an auto-detected option. If the sorted result looks scrambled, the separator is usually the cause: switch to New lines and sort again.

Handle names that are already “Last, First”

If your source list uses the “Smith, John” format, sorting by last name will not give the order you expect, because the surname is not the final word. Use the cleanup option Swap word order (“Smith, John” → “John, Smith”) before sorting. After the swap, each item reads first name first, and By last name produces a correct alphabetical order.

This two-step sequence is the reliable path for lists copied from directories, CRM exports, or forms that collect last name first.

Deal with titles and leading words

The sort menu includes a separate option, Titles (ignore “The”, “A”, “An”), which is intended for titles of works rather than people. For a guest list, decide how you want honorifics handled:

• Keep titles such as “Dr.” in the item. The last-name sort still uses the final word, so “Dr. Ann Baker” files under Baker.
• Remove titles with Find and replace if you want a clean name-only list. Enter the title and a space in the Find field, leave With empty, and choose Replace all.

The Ignore capitalization setting in Find and replace helps when titles appear in mixed case.

Verify the result before you leave

After sorting, scan the top and bottom of the list. Confirm that the first entry begins with an early-alphabet surname and the last with a late-alphabet one. If something is out of place, check for:

• Trailing spaces — run Trim spaces from each item.
• Extra whitespace inside names — run Remove extra whitespace.
• Duplicate entries — run Remove duplicates.
• A wrong separator — reset it to New lines and re-sort.

The Undo and Redo buttons let you step back through changes without re-pasting the list.

Export or reuse the sorted list

Once the order is correct, use Copy to clipboard to paste it into an email, document, or event spreadsheet, or Download as .txt to save a file. The Output separator control lets you choose how the copied result is formatted — for example, New lines for a plain column or Comma + space for pasting into a spreadsheet cell.

Because processing happens locally in the browser, the list is not uploaded during sorting, cleanup, or export. That makes the tool suitable for guest lists and contact lists that contain personal names.

No. Sort My List processes your list entirely in your browser, and according to the site, your list is never uploaded. The page states plainly: “Everything happens in your browser: your list is never uploaded.” This applies to the sorting, cleaning, and reformatting tools alike, including the individual tool pages, where the site says your list “follows you from tool to tool, and it stays in your browser the whole time.”

What “in your browser” means in practice

When you paste a list into the editor and choose an action — alphabetize A → Z, sort by last name, remove duplicates, strip line breaks, find and replace, and so on — the work is done by code running on your own machine. There is no round trip to a server for the list contents.

That matters for two reasons:

• Nothing to store. If the list isn’t sent, there’s no server-side copy to retain, log, or expose.
• Nothing to intercept in transit. The data doesn’t travel over the network as part of the operation, so it isn’t exposed to network-level capture the way an upload would be.

The site frames this as “Private by design” and notes it has operated this way “since 2008.”

Why this matters for sensitive lists

The tool is built for exactly the kinds of lists people are cautious about. The sample list on the homepage is a guest list (“Tonight’s guest list”), and the tool set includes email-focused operations: cleaning an email list, extracting addresses from text, sorting emails by domain, removing one list from another (for unsubscribes and bounces), and finding near matches like jon.smith@ versus jonsmith@.

For those tasks, browser-side processing changes the risk profile:

This is a meaningful difference from paste-into-a-web-form tools that process on a server. It does not, however, make the tool a substitute for your own judgment about where the file lives afterward — see the limits below.

Limits worth knowing before you rely on it

• Your device and browser still matter. Processing locally means the list exists in your browser’s memory and possibly in clipboard or downloaded files. Clearing the page, closing the tab, or downloading a .txt copy are all under your control, but so is any local retention.
• Downloading and copying create new copies. The editor offers “Download as .txt,” “Copy to clipboard,” and “Print.” Each produces a copy outside the tool’s boundary — a file on disk, clipboard contents, or a print job. Treat those as you would any sensitive document.
• The site does not claim more than browser-side processing. The stated guarantee is that the list is never uploaded. It does not describe server-side accounts, cloud storage of lists, or syncing across devices — and the tool set (open a text file, download as .txt, copy, print, clear) is consistent with a local-only workflow.
• Pricing and login are not specified in the available material. The page mentions a “subscribe” keyword but provides no pricing page or account details, so don’t assume either a paid tier or a no-login guarantee beyond what’s stated.

How to verify it yourself

If you want to confirm the behavior rather than take the site’s word for it:

1. Open your browser’s developer tools and switch to the Network tab.
2. Paste a distinctive test list (for example, invented names or a made-up address like [email protected]).
3. Run an operation — alphabetize, remove duplicates, sort emails by domain.
4. Watch the Network tab. If the list were being uploaded, you would expect a request carrying that distinctive text. The site’s claim is that no such request occurs.
5. Optionally, disconnect from the network after the page loads and repeat the operation. If it still works, the processing is local.

This is a general verification method, not a report of a test performed for this article; results depend on your browser and any extensions you have installed.

Bottom line

Sort My List is a reasonable choice when you need to alphabetize, deduplicate, or reformat a list you’d rather not hand to a server — guest lists, contact exports, subscriber addresses. The site’s stated design is that processing happens in your browser and the list is never uploaded. Keep in mind that the copies you create afterward (downloaded .txt, clipboard, printouts) are yours to manage, and that the available material doesn’t address accounts, pricing, or cross-device storage.
