Random Combination Generator

Choose unordered subsets from a pasted list while preserving duplicate row identity. The complete workflow runs locally in this browser, with visible controls and a result you can inspect before copying or downloading.

How it works

  1. Assign every nonempty input row a stable position, including duplicate labels.
  2. Securely select the requested number of distinct row positions for each subset.
  3. Normalize position order only for whole-combination duplicate detection, not for display identity.

Worked example

Choosing 3 from six rows can produce {Alpha, Charlie, Foxtrot}; order inside the braces is not meaningful.

Limits and interpretation

  • Input is capped at 1,000 rows and 100,000 characters.
  • Subset size cannot exceed the number of input rows.
  • Unique-combination mode rejects requests larger than the computed n-choose-k space.

Privacy

Your inputs and generated results stay in this browser. This tool does not put them in a URL, analytics event, server log, or external request.

Frequently asked questions

How does Random Combination Generator make its random choices?
Each subset is an unbiased secure sample of row positions without replacement; optional whole-subset uniqueness is checked explicitly.
Does Random Combination Generator upload my inputs or results?
No. Values stay in the current browser tab and are not placed in the URL, analytics, storage, or network requests.
When should I use Random Combination Generator?
Use it to select panels, small groups, feature bundles, or test subsets where internal order does not matter.
