使い方

使い方

  1. Paste up to 100,000 characters and choose the separator that divides your items.
  2. Choose whether to trim whitespace and ignore empty items, then randomize the list.
  3. Review the one-item-per-line result, copy it, or download it as a TXT file.

Explicit separators and item rules

Newline, comma, tab, semicolon, and custom literal separators are supported. You can trim surrounding whitespace and ignore empty items; when empty items are kept, they remain eligible for randomization as blank output lines.

Bounded local processing

Input is limited to 100,000 characters and 10,000 items. Parsing, shuffling, copying, and TXT download happen locally in your browser; no list is sent to a server.

Practical randomization

The tool uses a browser pseudorandom shuffle for everyday list ordering. It is not a cryptographic randomizer and should not be used for security, lotteries, or other high-stakes selection.
