#Novel Processor

Novel Processor is a one-stop cleanup tool built for web novels, e-books, and other long-form text. It auto-repairs formatting issues, strips ads, normalizes chapter titles, reorders by chapter index, and optionally does Trad/Simp conversion — turning chaotic novel text into something clean and readable.

#What problems does it solve?

Typical pain points with downloaded novels:

• Messy layout: paragraphs not separated, chapters running together, scattered blank lines
• Ad watermarks: downloader stamps, group-promotion lines, "split-volume reading" markers
• Inconsistent format: mixed Trad/Simp, full-width vs half-width chaos
• Broken line wrapping: sentences split mid-line, paragraphs broken at the wrong spots
• Chapter ordering: scrambled tables of contents, chapter titles without line breaks

#Page layout

Two columns:

• Left: file upload + text input + three primary action buttons + result card
• Right: three-section configuration Collapse + Protected Dictionary panel

#Left column: input & actions

#File upload

• Drag-and-drop or click; supports TXT, MD, and other text formats
• Multi-file mode by default — drop an entire novel collection at once
• In Single-File Mode (toggle in Advanced Settings), uploading a new file replaces the current one

#Three primary action buttons

When done, the result is auto-copied to clipboard and shown in the result card.

#Right column: three-section configuration

#1. Typesetting (expanded by default)

• Smart Line Break (on): detect paragraph boundaries via Chinese punctuation, pure-numeric lines, and special starters; re-merge broken sentences
  • Sub-toggle Paragraph Indent (visible only when Smart Line Break is on, default on): add \t to each paragraph head — gives book-style typography
• Paragraph Split (off by default): break long paragraphs into shorter ones via sentence detection (compromise English NLP + Chinese punctuation rules) — better for mobile reading

#2. Content Cleaning (collapsed by default)

• Chapter Title Formatting (on): recognize "Chapter X" / "第X章" patterns and normalize them
• Strip Line-End Digits (off): remove trailing digits only on lines ≥ 10 chars (avoids stripping years from short titles)
• Trim Spaces (on): strip leading/trailing whitespace per line
• Remove Adjacent Duplicates (off): drop only consecutive duplicate lines (not full-text dedup — preserves common short dialogue like "嗯" / "好")
• Special Start Text: enter the novel title or a recurring header word — matching lines are forced into their own paragraph (prevents incorrect merging)
• Filter Words + Filter Threshold:
  • Filter Words: comma-separated keywords (channel,downloader) — every matching line gets dropped
  • Filter Threshold: lines longer than N chars are exempt (kept even if they match) — protects body paragraphs. 0 disables the exemption.

#3. Advanced Settings (collapsed by default)

• Trad/Simp Conversion Segmented:
  • None → skip this step
  • Trad → Simp → uses tw → cn
  • Simp → Trad → uses cn → tw
• Single-File Mode: one file at a time
• Auto-Export (visible only in single-file mode): skip preview and download directly

#Protected Dictionary (shared with Chinese Converter)

Bottom-right of the page:

• Master toggle: enable / disable all rules
• Shows current s2t / t2s rule counts
• Manage Rules button: opens the drawer to add/edit/delete rules, plus batch import/export
• Inactive hint: if Trad/Simp conversion is set to "None", the panel shows a "rules currently inactive" hint

The dictionary is shared with the Chinese Converter tool (same localStorage key) — edit in one place, applies in both. Only participates in processing when Trad/Simp conversion is actually enabled in Advanced Settings.

#Full pipeline (Start Process button)

The complete pipeline triggered by the main button:

1. Trad/Simp conversion (if enabled): applies the appropriate protected rules
2. Normalize newlines + strip novel artifacts: unify \r\n → \n, remove common downloader watermarks / 分卷阅读 markers / horizontal-rule lines
3. Full-width → half-width: normalize Latin letters, digits, and punctuation
4. Chapter mark formatting: replace colons in 第X章： with spaces, compress redundant spaces around chapter markers
5. Chapter split (if enabled): break inline-written chapter titles
6. Keyword filtering (if filled): drop lines matching keywords (subject to threshold exemption)
7. Line-end digit stripping (if enabled): strip trailing digits on long lines
8. Paragraph splitting (if enabled): break long paragraphs
9. Smart line break / paragraph indent: re-merge broken sentences, add paragraph indent, collapse extra blank lines

#Result card

After processing:

• Auto-copied to clipboard
• Copy / Export / Edit in place: same as Chinese Converter
• Result → Source: pipe the result back into the input for further processing (rare)

With "Auto-Export" enabled, the preview is skipped and the file downloads immediately.

#Tips

#First-time use

• Test on a small slice (1-2 chapters) first; tune the config before processing the full book
• Start filter words with 1-2 obvious watermark terms; expand the list after verifying

#Power moves

• Filter Threshold is the key trick: set it to ~50 (or the average paragraph length) to surgically delete short watermark lines while keeping long body paragraphs
• Run Chapter Reorder standalone: when you only want to fix chapter order, click Chapter Reorder directly — don't run the full Start Process pipeline
• Pre-edit Protected Dictionary: for novels with rare Trad/Simp-mixed proper names, add them to the dictionary first, then run Start Process

#When it shines

• Format-broken text from pirated novel sites
• Novel collections harvested by scrapers / auto-downloaders
• Long-form text from OCR / PDF copying
• Pre-processing before importing into Kindle / Moon+ Reader / Apple Books

#Technical note

For deeply-obfuscated watermarks (scrambled-character promotional content), combine Filter Words with Filter Threshold as a first pass. Extremely obfuscated patterns are best handled by the Text Toolbox with a custom regex, then fed back here for layout.
