How to use Split a List
- 1. Paste your list. Enter your items into the input pane, one per line. Any long list you want broken into smaller chunks works here.
- 2. Set the chunk size. Enter how many items belong in each chunk using Items per chunk. The list is divided into consecutive groups of that size, each separated by a blank line.
- 3. Copy the split result. The output pane shows your list broken into chunks, each on its own block separated by a blank line. Copy the result wherever the divided list is needed.
When to use Split a List
Split a List divides a single list into smaller chunks of a fixed size, each shown as its own block. Use Split a List whenever a long list needs to be broken into manageable pieces rather than joined into groups on one line.
- Dividing a long list for multiple team members. A list of a hundred tasks needs to be split among four people, and setting the chunk size to twenty five divides the list into four even blocks to distribute.
- Breaking a large dataset into paging chunks. A long list of records needs to be processed in fixed-size batches, and splitting it into chunks of a set size shows you exactly what each batch will contain.
- Preparing a list for a multi-part email. A long list is too long for a single message and needs to be broken into shorter sections to send across a few separate emails, which splitting handles directly.
- Reviewing a list in smaller, readable sections. A long list is hard to review all at once, and splitting it into chunks makes it easier to check a manageable section at a time before moving to the next.

About the Split a List tool
Split a List runs as plain JavaScript in your browser tab, with no server behind it. Split list items into chunks. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's List Tools section, 114 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Items per chunk 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.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Split a List 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.
