FAQ
Short answers before you paste real data.
Does this case converter upload my text?
No. Case conversion, text cleanup, output generation, and copy actions run in the current browser tab.
How does title case work?
Title case lowercases the text first, then capitalizes the first letter of each word. It is predictable for quick cleanup, but it does not try to follow every style guide rule for small words.
What does sentence case change?
Sentence case lowercases the text, then capitalizes the first letter at the start of the text, after sentence punctuation, and after line breaks.
How are duplicate lines removed?
Duplicate-line removal keeps the first exact line and removes later exact matches. It does not ignore case or trim lines before comparing them.
Can I clean very long text?
The tool is designed for pasted snippets, lists, drafts, and small documents. Very large files are better handled in a text editor.
