Frequently asked questions

What can I do with this tool?
Quickly add quotes, comment markers, list bullets, or any string to the start or end of every line — useful for SQL IN-lists, config files, and Markdown.

Yes. Toggle ‘Skip empty lines’ to leave empty lines alone while transforming the rest.
Does it process my text in the cloud?
No. Transformation happens locally in your browser.
