How do I use Case Converter Online?

Paste your text into the input area of Case Converter Online. Results — word count, sorted lines, converted case, diff, or formatted output depending on the tool — appear instantly as you type. Copy the result with one click.

Can I do regex find-and-replace in this tool?

The dedicated Find and Replace tool and Regex Tester on PromptSpace support full JavaScript regex including flags (g, i, m, s, u), capture groups, and lookaheads. Bulk replace across large documents runs entirely in-browser.

What is Markdown and how do I convert it?

Markdown is a lightweight plain-text format with symbols like # for headings and ** for bold. PromptSpace has a Markdown Preview tool, a Markdown-to-HTML converter, an HTML-to-Markdown converter, and a Strip Markdown tool — pick the one that matches your direction of conversion.

How does Case Converter Online handle Unicode and emoji?

Case Converter Online operates on UTF-8 text with full Unicode support. Emoji, accented characters, RTL scripts (Arabic, Hebrew), CJK (Chinese/Japanese/Korean), and combining marks are counted and transformed correctly — no data loss on non-ASCII input.

How do I sort lines alphabetically or remove duplicates?

Use the Line Sorter tool: paste your text, pick ascending or descending, and optionally toggle "remove duplicates" and "case-insensitive". Trailing whitespace and empty lines are handled predictably.

Is there a character or word limit on Case Converter Online?

No. Because Case Converter Online runs in your browser and never uploads data, you can process novel-length text (hundreds of thousands of words) without hitting a rate limit or file cap.
