Team Dividerの使い方
Automatically divide members into balanced teams. Leader designation is also possible.
What is Team Divider?
Team Divider splits a list of members into 2 to 10 balanced teams. Uneven group sizes are adjusted automatically (11 people into 3 teams becomes 4+4+3). Leader designation keeps experienced members spread across teams, which matters for sports and mixed-skill group work. Bulk paste input and drag-and-drop adjustment are both supported.
使い方の手順
Enter member names
Type names one by one or paste a newline-separated list (e.g. from a spreadsheet column). Appending ", Leader" after a name marks that person as a leader and distributes them across teams evenly.
Choose the number of teams
Use the slider to set between 2 and 10 teams. If members don't divide evenly the remainders are distributed one per team. Setting more teams than members creates empty teams, so double-check the numbers.
Run the divider
Click "Divide Teams". Leaders are placed one per team first, then the remaining members are assigned randomly. Each result differs, so re-run if the distribution looks off, but be aware that rerunning changes all assignments.
Fine-tune and export
Drag members between teams to honor friendships or role requirements. Export the final assignment as text, CSV, or JSON — otherwise the result is lost when you close the browser.
A concrete scenario
Dividing a 40-student class into 4 teams for sports day
Situation
Previously the teacher had four team captains draft members one at a time, but it took 20 minutes and left the last-picked kids uncomfortable.
How it played out
Paste the 40 names from a spreadsheet, append ", Leader" to the four chosen captains, set teams to 4, and click divide. In under a minute each team has one captain plus nine members, assigned randomly. Announcing "the tool decided" removes the social pressure. Export the CSV and print the rosters for the event.

Common mistakes to avoid
- 1Trailing whitespace in names creates duplicates — eyeball the list after pasting.
- 2Skipping leader designation concentrates experienced members in one team, causing skill imbalance.
- 3Setting more teams than members, leaving empty teams.
- 4Forgetting to export and losing the result when the browser closes — rerunning produces a different outcome.
