What this tool does

The converter helps prepare headings, descriptions, lists, and text fragments without rewriting them by hand.

How to use

  1. Paste text into the input field.
  2. Choose the case format you need.
  3. Copy the finished result.

Available case modes

The converter changes text to uppercase, lowercase, title case, or sentence case. The result updates in the browser as soon as you paste text or switch the selected mode.

Title case capitalizes the first letter after a space, hyphen, dash, slash, or opening bracket. Sentence case first lowercases the text, then capitalizes the first letter at the start of the text and after periods, question marks, and exclamation marks.

Where it helps

The tool saves time when preparing headings, lists, product descriptions, file names, table labels, and interface string drafts. It is especially useful when copy comes from mixed sources and needs one consistent case quickly.

Paste a fragment from an email, spreadsheet, or CMS, choose the required format, and copy the result. Line breaks are preserved, so the converter also works well for short lists.

Style and limitations

Conversion follows formal rules and does not know your editorial style guide. Acronyms, brand names, personal names, technical terms, and words with intentional casing should be reviewed after conversion.

Title rules differ by language and style: some guides capitalize most important words, while others capitalize only the first word. Treat the output as a quick draft and align the final version with the style you need.
