List Converter

A list converter reformats simple lists between comma-separated text, separate lines, bullet lines, plain lines, and numbered lines. It is intended for uncomplicated items, not structured CSV data.

Most line-based modes trim each line, remove a possible leading bullet or number-like prefix, discard empty lines, and then add the requested formatting. Comma-to-lines mode instead splits the original input directly at every comma.

Lists often move between spreadsheets, forms, documents, and messaging apps. Reformatting them automatically saves time and produces consistent separators.

• Turn a short comma list into one item per line.
• Join line items with comma-space separators.
• Add bullets or sequential numbers.
• Remove common bullet and numbering prefixes.

For line-based modes, each line is tested against a broad prefix pattern containing whitespace followed by one or more hyphens, asterisks, bullet characters, digits, periods, or closing parentheses, then optional whitespace. The matched prefix is removed, the remainder is trimmed, and blank results are dropped.

Bullet output adds “• ” to each cleaned line. Numbered output starts at 1 and adds a period and space. Comma output joins cleaned lines with “, ”. Comma-to-lines does no quote-aware parsing: it trims pieces around literal commas and removes empty pieces.

The prefix rule is intentionally simple and can remove meaningful leading punctuation or digits. For example, a line beginning with a numeric value followed by punctuation may be interpreted as numbering. Review data-like lists after conversion.

Quoted commas, escaped delimiters, embedded newlines, and CSV headers have no special meaning. A field such as “Smith, Jane” is split into two items even if surrounded by quotes.

Consistent list structure makes content easier to paste, sort, deduplicate, or import. Preserving data semantics is more important than appearance, so complex records should use a real CSV parser or the source application's export tools.

Conversion is based on literal delimiters and a prefix-removal pattern. It does not infer columns, data types, quoting rules, or nesting.

clean lines → filter empty items → join or prefix for selected mode

Item

A nonempty trimmed comma piece or cleaned line.

Prefix

Leading bullet/number-like characters matched for removal.

List Converter is designed for quick, simple reformatting. Its literal comma splitting and broad prefix cleanup are predictable, so inspect complex or data-sensitive lists before using the result.
