Text tool
Case Converter
Clean up pasted text and convert it into a more useful case format.
Common case conversions
Case conversion is useful when editing headings, importing spreadsheet labels, preparing social posts, or normalizing copied text from another document. It saves time when the text is mostly right but the capitalization is inconsistent.
Available modes
- UPPER: turns all letters into uppercase for short labels, codes, or emphasis.
- lower: normalizes text for tags, filenames, slugs, or simple lists.
- Title Case: capitalizes the first letter of each word for headings and titles.
- Sentence case: makes the text read more naturally for paragraphs and UI labels.
Example
Input: quick guide to json formatting
Title Case result: Quick Guide To Json Formatting
Human-corrected result: Quick Guide to JSON Formatting
Automatic conversion gets most of the work done, but acronyms, names, and brands may still need a final human review.
FAQ
Will title case handle every style guide perfectly?
No. Style guides disagree about small words like "to", "for", and "and". Use the result as a quick draft, then adjust it if your publication has specific rules.
Can I use this for spreadsheet labels?
Yes. Paste labels or column names, convert them, then copy the cleaned result back into your spreadsheet or document.
Why do acronyms sometimes look wrong?
The browser cannot always know that a word is an acronym or brand name. Review terms like JSON, HTML, SEO, iPhone, and JavaScript manually.
