Bulk Slug Generator

Turn a whole list of blog titles, product names, or page headings into clean, URL-safe slugs — all at once, right in your browser. Paste one title per line, or drop in a CSV/TSV export, and get back de-duplicated, ready-to-use slugs with no uploads and no signup.

What it does

  • Converts a full list of titles to slugs live as you type — one title per line, blank lines skipped without breaking the order.
  • Handles accented characters properly: “Café Menu” becomes cafe-menu, not café-menu or a mangled c-f-.
  • Auto-resolves collisions. If two titles would produce the same slug — like “Hello World” and “Hello, World!” — the second one automatically gets a -2 suffix instead of silently overwriting the first.
  • Choice of separator (hyphen or underscore) and casing (force lowercase, or preserve the original case).
  • Optional stopword stripping (a, the, of, in…) for leaner, SEO-style slugs.
  • Word-boundary-aware max-length truncation — it never cuts a slug mid-word or leaves a dangling separator.
  • Import straight from a CSV or TSV file and pick which column holds your titles, instead of retyping everything into a text box.
  • Export as a plain list, a CSV of original+slug pairs, or JSON (array or object map).

How to use it

  1. Paste your list of titles into the box, one per line — or drop a CSV/TSV file and choose the column to slugify.
  2. Set your separator, casing, and (optionally) a max length or stopword stripping in the sidebar.
  3. Check the live table for any titles flagged as de-duped, and the summary line for a quick collision count.
  4. Copy the output or download it in the format you need.

Who this is for

Anyone bulk-importing content who needs slugs to match: migrating a blog to a new CMS, generating clean URLs for a product catalog, building redirect maps, or preparing a batch of pages for static-site generation. If your titles already live in a spreadsheet, there’s no need to retype them — pull the list in as a CSV/TSV directly, or hand it over from the CSV cleaner, Merge CSVs, or XLSX viewer tools using their built-in “Send to” button — no re-export needed.

Need just one slug instead of a whole list? Use the plain Slug generator — same conversion rules, single-title version.

FAQ

Will this handle duplicate titles correctly?

Yes — this is the one thing most bulk slug tools get wrong. Two different titles that would otherwise produce the same slug are automatically resolved in the order they appear, with -2, -3, and so on. The first occurrence always keeps the clean, unsuffixed slug.

What happens to accented or non-English characters?

Accented Latin characters (é, ñ, ü, ç, etc.) are converted to their closest plain-ASCII equivalent — the same conversion table used by the single-title Slug generator, so results match exactly between the two tools.

Can I use this with a spreadsheet instead of typing titles by hand?

Yes. Drop a CSV or TSV file onto the tool and pick which column to slugify — the rest of the file is ignored. It also accepts an incoming table sent over from the CSV cleaner, Merge CSVs, XLSX viewer, or Markdown Table → JSON Converter tools.

Does it flag near-duplicate titles, like typos of the same name?

No — this tool only catches titles that produce the exact same slug. For fuzzy/near-duplicate rows in a larger spreadsheet (e.g. “John Doe” vs “John Doee”), use the Fuzzy Duplicate Row Matcher first, then bring the cleaned list here.

Is anything uploaded to a server?

No. Everything — reading your file, converting titles, de-duplicating, exporting — runs entirely in your browser. Nothing is sent anywhere.
