How to use Tokenize a String
- 1. Paste the string. Enter the sentence or text you want broken into tokens into the input pane. Tokenize a String splits it according to the token type you select.
- 2. Choose Words or Characters. Set Tokens to Words to split on whitespace and get one word per line, or to Characters to get every single character listed on its own line, spaces included.
- 3. Copy the token list. Copy the resulting list of tokens, one per line, ready to paste into a spreadsheet, feed into another tool, or inspect one unit at a time.
When to use Tokenize a String
Tokenize a String splits text into a list of individual word or character tokens, one per line. It is a lightweight way to see exactly how a piece of text breaks down before writing tokenizing logic in code.
- Previewing input for an NLP pipeline. You are building a text-processing script and want to see exactly how a sample sentence would be tokenized into words before implementing the same logic in code.
- Counting characters for a font or layout test. You need a list of every individual character in a short string, including spaces, to check spacing or kerning in a font rendering test.
- Preparing a word list for a game. A word game needs each word of a sentence isolated onto its own line so it can be shuffled, hidden, or scored individually.
- Inspecting whitespace handling in a string. You suspect a string has irregular spacing and want to see how it splits into word tokens to confirm whether extra or missing spaces are causing unexpected token counts.

About the Tokenize a String tool
Tokenize a String does its work locally, right in the browser. Split a string into word or character tokens. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the String Tools collection on EditSafely, a set of 159 small, focused String utilities that share the same instant, private workspace.
You can shape the output with the Tokens setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Tokenize a String cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
