WordPress's sanitize_title() does the same core job: lowercase, strip accents, replace anything that isn't a letter, number or hyphen with a hyphen, then trim repeats.

Both platforms treat an ampersand as a word, not a symbol to strip, so “Hats & Gloves” becomes “hats-and-gloves” here.

How each platform builds a slug

WordPress's sanitize_title() function and Shopify's automatic product handle both do the same core job: lowercase the text, strip accents, turn an ampersand into “and”, replace anything that isn't a letter, number or hyphen with a hyphen, and trim repeated or trailing hyphens. This tool applies the same rules to a whole list at once.

Example

Title
Café au Lait Mug (12oz)
Slug
cafe-au-lait-mug-12oz

Accents are removed, parentheses become hyphens, and the result stays lowercase with no repeated hyphens.

Where to use the result

  • Bulk-generate product handles before a CSV import, so every row already has one instead of relying on Shopify or WooCommerce to build it automatically.
  • Build category or collection slugs ahead of a site restructure.
  • Turn on “make duplicates unique” when your list has repeated titles, which numbers them the same way WordPress and Shopify do (-2, -3, and so on).

Questions people ask

Do WordPress and Shopify build slugs exactly the same way?

Very closely for ordinary text: lowercase, hyphenated, accents stripped. Both platforms have their own edge cases for unusual characters, so always spot-check a slug that includes symbols or non-Latin text.

Can I set a maximum length?

Yes, set Max length above 0 and the tool cuts at the nearest hyphen rather than mid-word, matching how the platforms avoid overly long handles.

What happens to duplicate titles?

With “Make duplicates unique” on, repeats get -2, -3 and so on appended, the same pattern WordPress and Shopify use when a slug is already taken.

Does this check if the slug is already used in my store?

No, it only generates slugs from your list. Check against your live catalog before a bulk import if avoiding collisions with existing products matters.
