How to use Group List Items
- 1. Paste your list. Enter your items into the input pane, one per line. Any flat list that needs to be broken into equal-sized clusters works here.
- 2. Set the group size. Enter how many items belong in each group using Items per group. The tool batches your list into consecutive clusters of that size, in order.
- 3. Choose a separator within each group. Type the string to place between items inside a group in Separator within a group, such as a comma and space, so each group prints on its own line.
- 4. Copy the grouped result. The output pane shows one line per group, with items joined by your chosen separator. Copy the batched result wherever it is needed.
When to use Group List Items
Group List Items batches a flat list into fixed-size clusters, printing each group on its own line. Use Group List Items when a long list needs to be organized into consistent chunks instead of one item per line.
- Organizing players into teams. A signup list of twenty names needs to become five teams of four. Setting the group size to four splits the list into evenly sized team rosters.
- Batching API requests into fixed-size chunks. An API only accepts ten IDs per request, and you have a list of a hundred. Grouping the IDs into batches of ten prepares them for looping over requests.
- Laying out a schedule in pairs. A list of participants for a round-robin schedule needs to be arranged into pairs for each round, and grouping by two produces those pairings directly.
- Formatting a phone number into groups of digits. A list of individual digit lines needs to become groups of three or four for a readable phone number format, which grouping and a chosen separator handles.

About the Group List Items tool
Group List Items is a free online tool that works entirely inside your web browser. Create groups of multiple list items. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 114 List utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Items per group and Separator within a group, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Does Group List Items 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.
