Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To convert text case, paste your content into the Case Converter and choose a mode. Uppercase makes every letter capital, lowercase makes them all small, title case capitalizes the main words, sentence case capitalizes the first letter of each sentence, and swap case inverts the existing capitalization of each letter.
The result updates so you can review it, then copy it back with one click for use in headlines, support replies, documentation, or marketing copy. The conversion happens locally in your browser, so even long passages of text stay private on your device.
The Case Converter is focused on normal text and copy cleanup rather than developer identifier casing. It handles the everyday job of fixing ALL CAPS pastes, inconsistent headlines, or text typed with caps lock on.
If you need programming-style transforms such as camelCase or snake_case, this is not the right tool — it intentionally stays simple and content-oriented so the common cases are fast and predictable.
Short answers for the questions people usually have before trying a utility like this.
