What does my-blog-post turn into?

By default my-blog-post becomes My Blog Post in Title Case. The tool splits on each dash, lowercases everything, then capitalises the first letter of every word. Switch to sentence case and the same input reads My blog post; switch to all lowercase and it reads my blog post; switch to raw mode and it reads my blog post too but with your original casing preserved if any letters were already capitalised.

Does it recognise both underscores and dashes?

Yes, and dots too. user_first_name, user-first-name and user.first.name all split into the same three words User First Name. You can even mix them in one string: a-b_c.d splits cleanly into A B C D. Repeated separators like my--blog__post collapse into single spaces, so you never get double gaps in the output.

Can it split camelCase and PascalCase?

Yes. getUserName becomes Get User Name and FirstName becomes First Name because the tool inserts a boundary at every lowercase-to-uppercase transition. Acronyms stay together: parseHTMLContent reads Parse HTML Content rather than Parse H T M L Content, because a run of capitals followed by a capital-plus-lowercase is treated as one acronym word.

In Title Case, does of stay lowercase?

With the small words toggle on (the default), words like of, the, and, to and for stay lowercase unless they are the first word, so lord-of-the-rings reads Lord of the Rings. That matches how headlines are normally capitalised. Turn the toggle off and every word is capitalised, giving Lord Of The Rings instead. The first word is always capitalised either way.

How does batch conversion work?

Paste one slug per line and each line is converted on its own. Feed it my-blog-post then user_first_name on two lines and you get My Blog Post and User First Name back on two lines, in the same order. This is handy for turning a column of database keys or file names into a readable list. The copy button grabs the whole multi-line result at once.

Generate page titles from URL slugs

Your CMS exports a list of URL slugs like getting-started-with-vue and you need a column of human titles for a sitemap or a navigation menu. Paste the whole column, leave Title Case on, and read back Getting Started With Vue line by line. The small words toggle keeps of and the lowercase so the titles look hand written rather than machine stamped.

Turn database column names into form labels

A table has columns like first_name, date_of_birth and is_active and you are building a form by hand. Drop the column names in, switch the output to Title Case, and you have First Name, Date of Birth and Is Active ready to paste as field labels, with no manual editing of every underscore.

Read API or code identifiers out loud in a review

During a code walkthrough you hit identifiers like parseHTTPResponse and shouldRetryRequest. Paste them and the tool shows Parse HTTP Response and Should Retry Request, which is far easier to say in a meeting and to drop into a comment or a commit message that a non-coder will read later.

Clean up exported file names for a caption list

A folder of screenshots named summer_trip_2024 and beach.sunset.final needs friendly captions for a gallery. Batch the file names through, pick sentence case, and read Summer trip 2024 and Beach sunset final, then copy the lot in one click instead of retyping each caption.

Readable text

What this tool does

Unslugify reverses a slug, snake_case, dotted or camelCase string back into plain readable text. Paste my-blog-post and read My Blog Post; paste user_first_name and read User First Name. It recognises four kinds of word boundary at once: dashes, underscores, dots and the case transitions inside camelCase or PascalCase (so parseHTMLContent splits into Parse, HTML and Content without breaking the acronym). Pick the output casing you need: Title Case for headings, sentence case for prose, all lowercase, or a raw mode that only swaps separators for spaces and leaves your original casing alone. A Title Case toggle keeps small words like of, the and and lowercase the way real headlines are written. Drop in many lines and each one converts on its own line for batch work, then copy the whole result with one click. Everything runs in your browser tab, nothing is uploaded.

Common pitfalls

Expecting raw mode to split camelCase. Raw mode only swaps separators for spaces, so myBlogPost stays myBlogPost. Use Title, sentence or lowercase mode if you want camelCase boundaries split into separate words.
Wondering why an acronym is not split letter by letter. parseHTMLContent reads Parse HTML Content on purpose, because a run of capitals is treated as one word. That is the correct behaviour for HTML, API, URL and similar, not a bug.
Forgetting that the small words toggle only affects Title Case. In sentence case, lowercase and raw modes the toggle does nothing, so flipping it while in sentence case will look like it has no effect. Switch to Title Case first to see of and the change.

Privacy

Every step runs as plain JavaScript inside your browser tab: the word splitting, the casing and the small word rules. The slugs you paste and the text that comes out never leave the page and nothing is logged. One thing to know: the input and your style choice are written into the page URL so a share link reproduces your exact result, which means a shared link records that text in the recipient server access log. For anything sensitive, use the copy button and paste the text rather than the URL.
