How to use this list converter

Paste your list, one item per line, into the input box.
Check any options you need — sort, dedupe, add prefix/suffix.
The transformed list appears instantly on the right, ready to copy.

What is this useful for?

Common uses include turning a plain list into a SQL "IN" clause (with quotes as prefix/suffix), removing duplicate entries from exported data, or quickly reformatting a spreadsheet column into a comma-separated list.

In what order are operations applied?

Trimming and lowercasing happen first, then duplicate removal, then sorting, then reversing, and prefix/suffix are added last.

Can I use a custom separator like a comma?

Yes — type any separator you want in the Separator field, such as a comma, semicolon, or pipe character.
