Inputs and settings

Processed in this tab without uploading or storing inputs. Each text field is limited to 32 KiB and complete output to 1 MiB; additional format and model limits apply.

Results

Review the settings and run. Editing inputs clears old results.

Processing model and limits

Shuffle once, then distribute every row in round-robin order. Group sizes differ by at most one. Group count cannot exceed entry count; maximum-size mode uses ceil(entries / maximum) nonempty groups. Trims entries and skips blank rows. Duplicate names remain separate entries identified by list and original row. Each list: 32 KiB UTF-8, 2000 physical rows; each entry: 256 UTF-8 bytes. Values: 1–2000. Result: 1 MiB JSON. Local Web Crypto rejection sampling; at most 10000 random words per run. Each run is independent.
