Create a Symmetric List

Create a symmetric list with ease using the Create a Symmetric List Tool. Mirror your input vertically, choose whether to duplicate the center item, and control whether you include the original input or just the reversed copy. Live preview, import, export, and copy features included.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .csv, .tsv, .log, .json, .md, .ini, .yaml, .yml
Total items: 0
Options
Include center item twice
Reverse only (don't append original)

How to Use:

  1. Paste your list or import a file using Choose File.
  2. Enable or disable Include center item twice to decide whether the midpoint appears once or is mirrored.
  3. Toggle Reverse only to use just the reversed copy, without the original lines.
  4. View the symmetric output live in the right panel.
  5. Use Copy Output, Export to File, or Clear All as needed.

What Create a Symmetric List Tool can do:

  • Reflect your list top-to-bottom for symmetry.
  • Optionally remove the center item from the mirror for clean reflection.
  • Works in reverse-only mode if you only want the flipped version.
  • Updates live and supports import, export, and copying.

Example:

Input:

apple
banana
cherry

Output (with center included):

apple
banana
cherry
banana
apple

Output (with center excluded):

apple
banana
cherry
banana

Reverse only mode:

cherry
banana
apple

Common Use Cases:

Useful for artistic layouts, data reflections, visual patterns, and ensuring balance in content presentation. Great for poems, mirror sequences, and structured symmetry work.

Useful Tools & Suggestions:

If you’re creating a symmetric list, Mirror a List pairs perfectly it reflects your items so you get that balanced, palindromic structure. And if you’re starting from scratch or need to fill in gaps, Create a Custom List lets you define exactly what goes in before you build the symmetry. It’s great for visual layouts, puzzles, or just organizing content that needs to look and feel evenly structured.
