About List Sorter
List Sorter performs list sorter as a focused single-page utility. Sort a list of items alphabetically, by length, or numerically in ascending or descending order. Defaults are tuned for the common case so the first run is one click, with every option that matters exposed for the moments you need to fine-tune the result.
List Sorter is implemented on top of standard browser APIs. Inputs are read from the file picker or drop zone, decoded in the browser, processed, and re-encoded into the output format. Files up to 0 MB are well within the comfort zone of any modern browser.
List Sorter parses your file with standard browser APIs entirely inside the browser, applies the options you selected, and returns a download. The processing has no network step, which means a slow or intermittent connection does not slow down the work — once the page is loaded, only your CPU and RAM are involved.
If you fit any of these descriptions, List Sorter should slot cleanly into your workflow: writers cleaning copy before publishing; researchers normalising scraped text; translators aligning bilingual passages. The tool keeps the controls focused on what matters for each of these use cases.
The right moment to reach for List Sorter is when you have a focused text processing job that fits inside a browser tab. Open the page, drop in the file or paste your input, choose the options that matter, and the tool returns the result.
Constraints worth knowing about: inputs are capped at 0 MB to keep memory usage in a sensible range, one input is processed per run, and the tool must be loaded over HTTPS for the in-browser engine to work. These are properties of the architecture.
List Sorter sits in a small group of related tools. Useful neighbours include List Randomizer, List Deduplicator, Text to List, and Sentence Reorder. They are designed to compose: the output of one is a sensible input to the next, so a multi-step task is usually a sequence of single-click operations.
List Sorter is built around steady iteration on a small set of options rather than feature creep. Every additional setting attracts a slightly different audience, but a long settings panel makes the common case slower for everyone. The current controls reflect what users of the tool actually use.
List Sorter returns the result as a download. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
A short note on how List Sorter came to look the way it does: every iteration started by watching how someone unfamiliar with the tool actually used it, then removing whatever got in their way. That is why the upload area dominates the screen, the run button is bigger than the secondary controls, and the result panel is unmissable when the job finishes.
List Sorter produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
If you want to get the most out of List Sorter, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
When something goes wrong, the cause is usually one of three things: a malformed input, a browser that is out of memory, or a corporate proxy that is interfering with the page's static assets. The first two are easy to diagnose; the third typically requires asking your IT team to allow standard browser APIs to load.
List Sorter is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Reach the List Sorter page in your browser to begin.
- 2Drop a text file onto the upload area, or click to pick one from your device.
- 3Adjust the options to match what you need. Sensible defaults cover the most common case, so you can usually skip this step.
- 4Click to start the job. The engine (standard browser APIs) processes the input in the page; you can watch the progress indicator until it completes.
- 5Save the output when it is ready.
- 6Re-run with different settings as often as you want. Each run produces a fresh output and the original file on disk is never modified.
Common use cases
- Diff two drafts of a document side by side using List Sorter.
- Sort a list of items alphabetically before publishing it.
- Reformat a JSON blob copied from a log into something readable.
- Convert a column of names into a comma-separated list for a script.
- Generate a slug from a long article title.
- Count the words in a draft to check it fits a brief.
- Translate plain text into Markdown for a static-site post.
- Encode user input safely before pasting it into HTML.
- De-duplicate a list of email addresses pulled from a form export.
FAQ
What sort options exist?
A–Z, Z–A, shortest first, longest first, and numeric ascending.
Is alphabetical sort case-sensitive?
No — sorting is case-insensitive by default for natural ordering.
How does numeric sort work?
Lines are sorted by parsing the leading number. Non-numeric lines sort as zero.
Can I sort CSV columns?
Use the list column extractor first, then sort the extracted column.
Is there a line limit?
No hard limit — your browser handles the processing.
Is my data safe?
Yes — all processing happens locally in your browser. Your text never leaves your device.
Can I self-host List Sorter for my team?
List Sorter is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (standard browser APIs) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
How accurate is List Sorter?
List Sorter is built on standard browser APIs, which is the same class of engine used by professional text processing pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
Does List Sorter work on a phone or tablet?
List Sorter runs in any modern mobile browser — Safari, Chrome, Firefox and the in-app browsers in most messaging apps all support the underlying APIs. Performance depends on the device: a recent phone handles typical inputs nearly as fast as a laptop, while older devices may take a few seconds longer near the 0 MB ceiling. The interface lays out cleanly on small screens, so you do not need to pinch-zoom to see the controls.
Are there any usage limits on List Sorter?
Inputs are capped at 0 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run List Sorter as often as you need; every run produces a full-quality result.
Are there any hidden fees with List Sorter?
List Sorter is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
Is List Sorter lossless?
List Sorter is built to preserve quality wherever the underlying text format allows it. Operations that are mathematically lossless (e.g. structural transformations, lossless re-encoding) round-trip with no perceptible change. Operations that involve a lossy codec inevitably introduce small artefacts at the byte level, but the defaults aim at the sweet spot where output looks or sounds the same to a normal viewer or listener while still being meaningfully smaller or faster than the input.
Can I use List Sorter for commercial work?
List Sorter can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
