List Converter Online (Sort, Dedupe, Format)

Runs 100% in your browser — your files never leave your device.

Turning a raw dump of lines into a JSON array, an HTML list, or a comma-separated field comes up constantly. Paste your list, toggle the transforms you need — dedupe, trim, sort, reverse, lowercase — set prefixes, suffixes, and separators, and copy the result. Great for building arrays, SQL IN clauses, and markup lists.

How it works

  1. 1

    Paste your list

    One item per line.

  2. 2

    Pick transforms

    Sort, dedupe, trim, reverse, lowercase — all optional and live.

  3. 3

    Shape the output

    Set separator and item/list wrappers, then copy the result.
