One-click paragraph cleanup: with or without first-line indent, merge paragraphs, no / single / double blank lines, or split into one sentence per paragraph. Everything runs locally; nothing is uploaded.

Features
- Paste text to process (up to 10,000 characters).
- Indent dropdown: First-line indent / No first-line indent (default: First-line indent; always available).
- Gap dropdown: merge / no / single / double blank lines / split (one sentence each).
- “Process” applies the current settings; “Reset” and “Copy content” are available as needed.
How to Use
- Paste text in the input box.
- Choose indent and paragraph-gap (merge, spacing, or one-sentence split).
- Click “Process” to see the result below.
- To try another rule set, change the dropdowns and click “Process” again (always re-runs from the input above).
- Copy the result or reset to start over.
Notes
- Dropdowns only configure; click Process to apply.
- Each Process re-applies the current rules to the input above (does not stack on the previous result).
- Merge joins paragraphs into one block, then applies the indent option to that block’s first line.
- One-sentence split follows CJK/English sentence-ending punctuation rules (decimals like 3.14 stay intact).
- “First-line indent” adds two full-width spaces per paragraph (or to the merged block); max 10,000 characters; processing stays in the browser.
