# LiteParse Skill

Parse unstructured documents (PDF, DOCX, PPTX, XLSX, images, and more) locally with LiteParse: fast, lightweight, no cloud dependencies or LLM required.

## Step 0 - Use via npx, or install LiteParse

NOTE: Rather than installing `liteparse` globally, you can instead run it directly with `npx`, substituting `lit <args>` with `npx -y @llamaindex/liteparse <args>` in the commands below.

```bash
npx -y @llamaindex/liteparse
```

Otherwise if installing globally, use `pnpm install -g @llamaindex/liteparse` and then run `lit <args>`.

## Step 1 - Produce the CLI Command or Script

### Parse a Single File

```bash
# Basic text extraction
lit parse document.pdf

# JSON output saved to a file
lit parse document.pdf --format json -o output.json

# Specific page range
lit parse document.pdf --target-pages "1-5,10,15-20"

# Disable OCR (faster, text-only PDFs)
lit parse document.pdf --no-ocr

# Use an external HTTP OCR server for higher accuracy
lit parse document.pdf --ocr-server-url http://localhost:8828/ocr

# Higher DPI for better quality
lit parse document.pdf --dpi 300
```

### Batch Parse a Directory

```bash
lit batch-parse ./input-directory ./output-directory

# Only process PDFs, recursively
lit batch-parse ./input ./output --extension .pdf --recursive
```

### Generate Page Screenshots

Screenshots are useful for LLM agents that need to see visual layout.

```bash
# All pages
lit screenshot document.pdf -o ./screenshots

# Specific pages
lit screenshot document.pdf --pages "1,3,5" -o ./screenshots

# High-DPI PNG
lit screenshot document.pdf --dpi 300 --format png -o ./screenshots

# Page range
lit screenshot document.pdf --pages "1-10" -o ./screenshots
```

## Step 3 - Key Options Reference

### OCR Options

| Option | Description |
|--------|-------------|
| (default) | Tesseract.js - zero setup, built-in |
| `--ocr-language fra` | Set OCR language (ISO code) |
| `--ocr-server-url <url>` | Use external HTTP OCR server (EasyOCR, PaddleOCR, custom) |
| `--no-ocr` | Disable OCR entirely |

### Output Options

| Option | Description |
|--------|-------------|
| `--format json` | Structured JSON with bounding boxes |
| `--format text` | Plain text (default) |
| `-o <file>` | Save output to file |

### Performance / Quality Options

| Option | Description |
|--------|-------------|
| `--dpi <n>` | Rendering DPI (default: 150; use 300 for high quality) |
| `--max-pages <n>` | Limit pages parsed |
| `--target-pages <pages>` | Parse specific pages (e.g. `"1-5,10"`) |
| `--no-precise-bbox` | Disable precise bounding boxes (faster) |
| `--skip-diagonal-text` | Ignore rotated/diagonal text |
| `--preserve-small-text` | Keep very small text that would otherwise be dropped |

---

## Step 4 - Using a Config File

For repeated use with consistent options, generate a `liteparse.config.json`:

```json
{
  "ocrLanguage": "en",
  "ocrEnabled": true,
  "maxPages": 1000,
  "dpi": 150,
  "outputFormat": "json",
  "preciseBoundingBox": true,
  "skipDiagonalText": false,
  "preserveVerySmallText": false
}
```
