The text case converter applies browser Unicode-aware case operations and simple word transformations. It is useful for editing labels, headings, and identifiers without sending text away from the browser.

When to use this tool

  • Normalize a heading to uppercase or lowercase.
  • Turn words separated by spaces, underscores, or hyphens into a basic camelCase identifier.

How to use

  1. Enter or paste text.
  2. Choose upper, lower, title, or camel mode.
  3. Review and copy the transformed text.

Example

Basic camel case

Lite tools_example becomes liteToolsExample.

How it works

  • Upper and lower modes use locale-aware browser casing. Title mode capitalizes matched Unicode words; camel mode removes spaces, underscores, and hyphens before uppercasing the following character.

Limits and notes

  • Title casing is rule-based and does not apply language-specific headline style exceptions.
  • Camel mode is a basic separator transformation and does not tokenize every punctuation or acronym convention.
  • Some Unicode casing operations can change string length.

Frequently asked questions

Does title mode understand editorial style guides?

No. It capitalizes word starts and does not keep language-specific minor words lowercase.

Will camel mode preserve acronyms?

Not reliably. It applies simple casing rules rather than an acronym dictionary.
