List Group
Split a list into equal-sized groups with custom separators and optional padding. Free, instant, and runs entirely in your browser.
What is a list group tool?
A list group tool splits a flat list of items into smaller, equal-sized groups or chunks. It's useful for organizing data, creating batches for processing, or formatting output for code and scripts.
How do I split a list into groups?
Paste your list into the input field, set the group size, choose your split and join separators, and the grouped result appears instantly in the output area.
What does padding the last group do?
When padding is enabled, the last group is filled with empty items to match the specified group size, ensuring all groups have the same number of elements.
Can I use custom separators?
Yes. You can define any character or string as the input split separator, the join separator within groups, and the separator between groups (including newline).
Is my data safe and private?
Absolutely. All processing happens 100% in your browser. No data is sent to any server, and nothing is stored or uploaded anywhere.
Does this tool work offline?
Yes. Once the page loads, it works entirely offline since all processing runs in your browser with no server dependency.
What are common use cases for list grouping?
Common uses include batching database records, creating SQL INSERT groups, organizing IDs for API calls, splitting CSV data, formatting arrays in code, and preparing data for bulk operations.
Is there a limit on list size?
There is no hard limit. Since processing happens in your browser, performance depends on your device. Lists with thousands of items are handled smoothly.
Can I group by newline-separated items?
Yes. Set the split separator to a newline character to process lists where each item is on its own line.
Do I need to install anything?
No installation required. The tool runs directly in your web browser. Just open the page and start using it.
Is this tool free to use?
Yes, completely free with no sign-up, no limits, and no watermarks.
How to Use List Group
List Group splits a list into equal-sized chunks for teams, batches, or pages. It runs entirely in your browser, and your data is never uploaded.
- Enter your items in the input field, for example a,b,c,d,e,f,g,h, separated by commas.
- Choose the delimiter your list actually uses under "Split by:", such as a comma, space, or "Newline".
- Type how many items each chunk should contain in the "Group size:" field.
- Set the "Group sep:" field to the separator written between groups, such as a newline or a pipe.
- Enable "Pad last group" if the final chunk should be filled up to the full group size.
With 8 items and "Group size:" 3 you get groups of 3, 3, and 2 — turn on "Pad last group" to fill the last chunk up to 3.
