Rotate List - Shift List Items Left or Right Online

What Is a List Rotator?

The Rotate List tool lets you shift all items in a list to the left or right by a specified number of positions. When items are rotated off one end, they wrap around to the other end. This is useful for cyclic permutations, creating circular shifts, or reorganizing list data.

Split your input list by a character or regular expression, choose the rotation direction and number of positions, then view the rotated result with your chosen output separator.

How to Rotate a List

Paste or type your list into the Input List text area.
Choose a Separator Mode — use Literal for a fixed character or Regex for a pattern.
Enter the Input Separator that currently divides your items.
Set the number of Positions to Rotate.
Choose Rotate Left or Rotate Right direction.
Set the Output Separator and view the rotated list instantly.

Common Use Cases

Create cyclic permutations of data for scheduling or rotation systems.
Shift priority queues or ordered lists to bring certain items to the front.
Generate test data with circular shifts for algorithm testing.
Reorganize list items for display or reporting purposes.

Frequently Asked Questions

What happens when I rotate left by 1 position?

The first item moves to the end of the list, and all other items shift one position to the left. For example, [A, B, C] becomes [B, C, A].

What happens when I rotate right by 1 position?

The last item moves to the beginning of the list, and all other items shift one position to the right. For example, [A, B, C] becomes [C, A, B].

What if I rotate by more positions than there are items?

The rotation automatically wraps around. The tool uses modular arithmetic, so rotating a 5-item list by 7 positions is the same as rotating by 2 positions.

Can I use a regular expression as a separator?

Yes. Switch to Separate by Regex mode and enter a valid regex pattern.

Is my list data sent to a server?

No. All processing is done entirely in your browser. Your list data never leaves your device.
