When to use UPPERCASE
UPPERCASE is typically used for headings, acronyms, warning labels and data normalisation before comparison.
How word boundaries are detected
Words are split on spaces, punctuation, underscores and hyphens, and on case changes inside identifiers — so parseHTTPResponse becomes the words “parse”, “HTTP”, “Response”. Accented and non-Latin letters are preserved.
UPPERCASE examples

|---|---|
| user profile settings | USER PROFILE SETTINGS |
| getHTTPResponseCode | GETHTTPRESPONSECODE |
| Total_Order-Amount | TOTAL_ORDER-AMOUNT |
| the lord of the rings | THE LORD OF THE RINGS |
Frequently asked questions
Does the UPPERCASE converter upload my text?
No. Conversion runs entirely in your browser using JavaScript; nothing leaves your device.
Is there a length limit?
No hard limit. Inputs of several megabytes convert in milliseconds on modern devices.
