Document Parsing

LlamaParse

The world's first GenAI-native document parser. Specifically designed for RAG, it understands complex document structures, tables, and charts to create perfect LLM-ready data.

🦙 What is LlamaParse?

LlamaParse is a proprietary parsing service built by LlamaIndex. Unlike traditional OCR tools that just "read text," LlamaParse uses Generative AI vision models to "understand" the document. It can look at a complex PDF page with nested tables, charts, and columns, and reconstruct it into perfectly formatted Markdown that represents the semantic meaning, not just the layout.

🧠

GenAI Native

Built for LLMs, by LLMs

📊

Complex Tables

Unmatched table extraction

🧩

Multimodal

Extracts text & images

⚡

LlamaIndex

Native integration

💡 Key Benefit: LlamaParse supports natural language instructions. You can tell it: "Extract only the balance sheet table and format it as JSON," and it will intelligently follow that instruction during the parsing process.

✨ Why it's a Game Changer

SOTA Table Extraction

Often cited as the best-in-class for parsing complex financial tables that confuse other parsers.

Instruction Steering

Guide the parser with prompts like "Remove headers" or "Format dates as ISO8601".

Structured JSON Output

Can output strict JSON, making it easy to create structured databases from unstructured PDFs.

Multilingual Support

Handles documents in various languages effectively, maintaining character encoding and layout.

💻 Implementation Examples

1. Basic Parsing with LlamaIndex

import nest_asyncio
nest_asyncio.apply()

from llama_parse import LlamaParse

parser = LlamaParse(
    api_key="llx-YOUR_API_KEY",  # Get from LlamaCloud
    result_type="markdown",      # "markdown" or "text"
    verbose=True
)

# Parse a file
documents = parser.load_data("./complex_document.pdf")

print(documents[0].text)
# Output: High-quality Markdown representation

2. Steering with Instructions

parser = LlamaParse(
    api_key="llx-...",
    result_type="markdown",
    # Specific instructions for the parser
    parsing_instruction="""
    This is a medical report. 
    Please extract the 'Patient History' section intimately.
    Ignore the legal disclaimer at the bottom of pages.
    Format all tables as Markdown.
    """
)

documents = parser.load_data("./medical_report.pdf")

3. JSON Mode for Structured Data

parser = LlamaParse(
    api_key="llx-...",
    result_type="json"  # specific JSON output
)

json_objs = parser.get_json_result("./invoice.pdf")
print(json_objs[0]["pages"][0]["text"]) 
# Access structured elements, images, and metadata directly

🎯 Ideal Use Cases
