Formatting note
Keep the original beside the result
The original text is kept separate so you can switch modes without losing it. Case conversion changes capitalization only; it does not rewrite words, fix spelling, or preserve every language's typographic convention.
The quick guide
Choose the style for the job
Case conversion is useful for cleanup, but a final proofread still matters for names, acronyms, and house style.
Example
“a practical STUDY PLAN” becomes “A Practical Study Plan” in title case. The converter changes capitalization; it does not change the wording.
Limitations
Check proper nouns yourself
Automatic case rules cannot know every brand name, acronym, abbreviation, or language-specific convention. Review the output before publishing or submitting it.
FAQ
Can I recover the original after converting?
Yes. The original and converted output are shown separately, and switching modes does not replace the original text.
Why did an acronym change?
Case conversion applies a general capitalization rule and does not recognize every acronym. Restore special capitalization in the output when needed.
What if Copy does not work?
The tool reports a copy failure and leaves the output visible so you can select it and use your browser's normal copy command.
