How to use

1. Paste the labels, headers, or short phrases into the input panel. Line breaks are fine for a list.
2. Scan the output for brands, acronyms, and hyphenated compounds. Restore any spelling the mechanical pass flattened.
3. Copy the result into your design doc, spreadsheet, or CMS.

What this tool is for

Capitalized case (also called start case) puts a capital on the first letter of every word and lowercases the rest of that word. It is heavier than title case because small words like “Of,” “And,” and “The” are capitalized too. Product teams use it for short labels more often than publishers use it for headlines. This page is for tidying a list of feature names, form legends, or button-style phrases that your design system wants in Start Case.

How it works

The converter lowercases the whole string, then capitalizes every character that matches a word boundary followed by a word character (`\b\w`). A hyphen is a non-word character, so it creates a new boundary: “e-commerce” becomes “E-Commerce,” not “E-commerce.” Line breaks are kept; the letter after a newline is capitalized when it is a word character. Digits and punctuation stay where they are. There is no small-word list and no dictionary of brands or acronyms.

When to use it

Button and menu labels in a design system that specifies Start Case (“Save Changes”), spreadsheet column headers, form legends, short display names, and feature lists copied in lowercase. It is a fast way to make every word look intentional when title case would leave “of” and “the” small and you do not want that.

When not to use it

Do not run long article titles through capitalized case if your house style wants title case with small words left lowercase. Do not convert body paragraphs — every line will look like a label. Do not use it for programming identifiers (prefer camelCase or PascalCase). Do not expect “XML,” “iPhone,” or “NASA” to survive: the whole string is lowercased first, so acronyms become “Xml” and “Nasa.”

How it compares to related tools

Title case leaves a fixed list of minor words lowercase in the middle of a heading and treats hyphenated tokens as one word (“E-commerce”). Sentence case only capitalizes sentence starts — that is for emails and article bodies. Upper case shouts the whole string. PascalCase removes spaces. If Caps Lock inverted letters (hELLO), run Inverse Case first.

Common mistakes

Shipping a twenty-word blog title with every “Of” and “The” capitalized when the style guide wanted title case. Converting “iPhone” or “XML” and wondering why the brand spelling disappeared. Treating capitalized case as Chicago or APA title case. Pasting live URLs: letters inside the path are lowercased then re-capitalized at each word boundary.

Start case versus publishing title case

Start case / capitalized case is common in older desktop UIs and in some spreadsheet cultures: every word looks “finished.” Modern product writing often prefers sentence case for buttons (“Save changes”) because it is quieter and matches body text. English blog titles usually follow title case, which keeps short function words lowercase in the middle. Pick the pattern your design system names, convert a whole list here in one paste, then fix brands by hand.

Hyphens, newlines, and empty input

Because the engine uses `\b\w`, a hyphen splits “e-commerce” into two capitalizable units. Apostrophes and other punctuation can also create boundaries depending on the surrounding characters. Newlines are not removed — “hello\nworld” becomes “Hello\nWorld.” Empty input produces empty output. The converter does not trim spaces; it only changes letter case at word boundaries after the global lowercase pass.
