About List Item Counter
List Item Counter is a self-contained text processing workspace. Count items in a list with stats on total, unique, empty lines, and character counts. Open the page, get the result, close the tab — that is the entire workflow.
The right moment to reach for List Item Counter 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.
The execution path is auditable from the page itself: open developer tools, switch to the Network tab, run a job. The requests you see are static-asset GETs for the engine and the page resources. The actual work is JavaScript code running against the bytes already in your tab's memory.
Technically, the work is done by standard browser APIs, loaded as part of the page. Inputs are recognised automatically and validated before the engine begins processing. Files up to 0 MB are supported per run; that ceiling keeps browser memory usage stable on a wide range of devices.
The hard constraints are easy to remember. Maximum input: 0 MB. Multiple files per run: no — one input at a time, by design, to keep results predictable. The same controls apply on every run.
If you fit any of these descriptions, List Item Counter should slot cleanly into your workflow: researchers normalising scraped text; writers cleaning copy before publishing; students formatting essays. The tool keeps the controls focused on what matters for each of these use cases.
The output handed back by List Item Counter is the output file. If you would prefer to keep the result in the browser instead of downloading it, you can copy it from the result panel and paste it directly into another tab — useful when the next tool in your workflow expects pasted text rather than a file.
If your task needs more than one step, chain List Item Counter with List Deduplicator, List Sorter, and Word Counter. Each tool produces output that is a clean input to the next, so multi-step workflows are just a matter of opening the next tool in a new tab and continuing.
List Item Counter is honest about scope: it handles a single, well-defined text processing step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.
Some context on why List Item Counter exists in this form: modern File APIs, high-performance JavaScript engines, and well-maintained open-source libraries now make it possible to perform text processing work entirely in the browser. List Item Counter is built on top of that capability, which is why a single page can host the full pipeline.
As a single-page tool, List Item Counter stays focused on one text processing step. Multi-step workflows are composed by chaining adjacent tools — each tool produces a standard file the next one can read directly, so a longer pipeline is just a sequence of short tab-and-tab visits.
If you want to get the most out of List Item Counter, 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.
If the result is not what you expected, the most common causes are easy to check. Confirm the input is under the 0 MB ceiling — files just above the cap fail silently because the engine refuses to allocate the buffer. Confirm the input is one of the supported formats. And if the page itself feels slow, try closing other heavy tabs to free up memory; the engine runs in your browser, so it competes for the same resources as everything else open.
List Item Counter 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 Item Counter page in your browser to begin.
- 2Add your text input by dropping it onto the page or browsing for it.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Trigger processing. standard browser APIs reads your input, applies the transformation, and writes the result back into the page.
- 5Download the result. The file is generated in your browser and saved through your normal download flow.
- 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.

- Re-case a title from ALL CAPS to Title Case.
- Count the words in a draft to check it fits a brief.
- Encode user input safely before pasting it into HTML.
- Reformat a JSON blob copied from a log into something readable.
- De-duplicate a list of email addresses pulled from a form export.
FAQ
What stats does it show?
Total lines, non-empty items, empty lines, unique items, and total character count.
Does it number the items?
Yes — the output displays each item with a line number for easy reference.
How are unique items counted?
Uniqueness is determined case-insensitively after trimming whitespace.
Does it count blank lines?
Yes — blank lines are counted separately and reported in the statistics.
Can I count words instead?
Use our Word Counter tool for word-level counting.
Is my data safe?
Yes — all processing happens locally in your browser. Your text never leaves your device.
How often is List Item Counter updated?
List Item Counter is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
Can I use List Item Counter on documents that contain personal data?
Your file is processed inside your browser by standard browser APIs. The engine reads the file's bytes from your tab's memory, computes the result, and writes the result back into the tab. You can confirm what the page does by opening developer tools and watching the Network tab during a run — the requests you see are for the tool's static assets only.
How long does Favtoo retain my data after using List Item Counter?
Favtoo keeps no copy of your file because Favtoo never receives your file. List Item Counter runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
Is there a programmatic version of List Item Counter?
List Item Counter is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (standard browser APIs) is open-source and can be used directly from your own code.
Can List Item Counter run inside a corporate firewall?
List Item Counter 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.
Are there any restrictions on using List Item Counter at work?
List Item Counter 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.
Does List Item Counter work in Safari, Firefox, Chrome and Edge?
List Item Counter works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
