How slugify batch works
This tool slugifies every line in a list at once, so you can turn a whole column of titles, product names, or headings into clean URL slugs in one pass instead of converting them one by one.
Paste one string per line, pick a separator (hyphen or underscore), and the tool runs the same slug algorithm on each line independently. Each output slug corresponds to the input line at the same position. The slug is built by lowercasing, removing accents, stripping special characters, and joining words with your separator.
The transformation matches the single Slug Generator. Empty lines are preserved and stay empty in the output, so your line numbering never shifts and every input line maps to exactly one output line.
