AM Supplier titles in ALL CAPS, headings written in three different styles, a product name that needs to become a URL handle: fixing case by hand is slow and it is easy to miss a word. This case converter changes text between the common formats in one click and cleans up extra spaces and line breaks while it is at it.
Everything runs in your browser. Your text is not uploaded or stored.
How to use the case converter
- Paste your text into the box at the top of this page. One line or hundreds of lines both work.
- Click the case you want. The text in the box changes immediately.
- For messy pasted text, click remove extra spaces or remove line breaks first, then convert.
- Check brand names, acronyms and model numbers, which no converter can guess correctly (see below).
- Click copy and paste the result where it belongs.
Every case, with an example
| Case | Example | Use it for |
|---|---|---|
| UPPERCASE | LINEN APRON WITH POCKETS | Short labels, buttons, SKU codes |
| lowercase | linen apron with pockets | Tags, emails, a clean start before another conversion |
| Title Case | Linen Apron With Pockets for Bakers | Product titles, headings, blog titles |
| Sentence case | Linen apron with pockets for bakers | Headings in a relaxed style, descriptions, meta descriptions |
| Capitalized Words | Linen Apron With Pockets For Bakers | Names and places, where every word is capitalized |
| aLtErNaTiNg | lInEn ApRoN | Memes and jokes only |
| snake_case | linen_apron_with_pockets | Database fields, CSV column names, file names |
| kebab-case | linen-apron-with-pockets | URLs, Shopify handles, CSS classes |
| camelCase | linenApronWithPockets | JavaScript variables and JSON keys |
How Title Case works here
Title Case follows the AP Stylebook rule for composition titles: capitalize the principal words, including prepositions and conjunctions of four or more letters, and keep articles and short connecting words lowercase. In practice that means:
- Lowercase a, an and the, the conjunctions and, but, or, nor, for, so and yet, and prepositions of three letters or fewer such as at, by, in, of, on, to and up.
- Capitalize nouns, verbs (including is and are), adjectives, adverbs, pronouns and longer prepositions such as with, from, into and over.
- Always capitalize the first and last word, even when it is a short word.
So "the best linen apron for bakers with big pockets" becomes "The Best Linen Apron for Bakers With Big Pockets". Chicago style and APA differ on some words, such as whether "with" is capitalized, so if you follow a different style guide, check the prepositions after converting. Capitalized Words is the simpler option: it capitalizes every word, small words included.
Cleaning up pasted text
Text copied from PDFs, spreadsheets, emails and supplier pages often carries double spaces, spaces at the start or end of lines and hard line breaks in the middle of sentences. Remove extra spaces collapses every run of spaces into one and trims the ends of lines. Remove line breaks joins the lines into one block, which is what you want for a product title or a meta description pasted from a document. Run these before converting case, so the result is clean in one pass.
Words no converter can guess
A converter only knows letters, not meaning. After converting, check these by hand:
- Brand names with unusual capitals, such as iPhone, eBay or YouTube. Title Case turns them into Iphone, Ebay and Youtube.
- Acronyms and units, such as USB-C, LED, XL or mAh. Lowercase and Sentence case flatten them.
- Model numbers such as RTX 4070 or the letters in a SKU.
- Proper nouns in Sentence case. Names of people, places and brands after the first word become lowercase.
Use cases for store owners
Product titles
Imported and supplier titles often arrive in ALL CAPS or with random capitals. Google's Shopping ads editorial standards reject gimmicky or excessive capitalization, and Amazon's title guidelines discourage all caps as well, so convert to Title Case before a title reaches your feed or listing. Consistent case across a collection also looks more trustworthy. The product title SEO guide covers what the title should contain, and the character counter checks the length.
Headings and blog titles
Pick one style for the whole site, Title Case or Sentence case, and apply it to every H1 and H2. Sentence case reads more casually and is easier to keep consistent. The word counter helps with the body text underneath.
URLs and handles
kebab-case is the standard for URLs. Google's URL guidelines recommend hyphens rather than underscores to separate words, and lowercase avoids duplicate URLs on servers that treat case as different. Shopify builds a handle from the title automatically, but you can edit it in the search engine listing section. Changing the handle of a live page changes its URL, so keep the redirect option checked and test the old address with the redirect checker.
Fixing case on hundreds of products
This tool works on text you paste, which is fine for a handful of titles. You can paste a column of titles from a spreadsheet export, convert them all at once, and paste them back before a CSV import. The Shopify bulk edit guide explains that workflow.
