DataFrameIt

English · Português · Español

Enrich DataFrames with LLMs, simply and in a structured way.

DataFrameIt processes text in DataFrames using Large Language Models (LLMs) and extracts structured information defined by Pydantic models.

Installation

pip install dataframeit[openai]       # OpenAI (default provider)
pip install dataframeit[google]       # Google Gemini
pip install dataframeit[anthropic]    # Anthropic Claude
pip install dataframeit[groq]         # Groq
pip install dataframeit[codex]        # Official Codex SDK (experimental)
pip install dataframeit[claude-code]  # Claude Code via the Claude Agent SDK
pip install dataframeit[all]          # all providers except Codex, web search, Polars and Excel

Optional extras: search (Tavily), search-exa (Exa), search-all, polars, excel.

Set up provider authentication:

export OPENAI_API_KEY="your-key"  # or GOOGLE_API_KEY, ANTHROPIC_API_KEY, GROQ_API_KEY

The experimental codex provider is optional, is not part of the all extra, uses the bundled runtime and requires local file-based authentication. See the installation docs to set up the extra and the credentials.

Quick Example

from pydantic import BaseModel
from typing import Literal
import pandas as pd
from dataframeit import dataframeit

# 1. Define what to extract
class Sentiment(BaseModel):
    sentiment: Literal['positive', 'negative', 'neutral']
    confidence: Literal['high', 'medium', 'low']

# 2. Your data
df = pd.DataFrame({
    'text': [
        'Excellent product! Exceeded my expectations.',
        'Terrible service, never buying again.',
        'Delivery was fine, product is average.'
    ]
})

# 3. Process!
result = dataframeit(df, Sentiment, "Analyze the sentiment of the text.")
print(result)

Output:

text	sentiment	confidence
Excellent product! ...	positive	high
Terrible service...	negative	high
Delivery was fine...	neutral	medium

Field and class names are arbitrary; the examples in the example/ notebooks use Portuguese ones.

Features

• Multiple providers: OpenAI, Google Gemini, Anthropic and Groq with their own extras, any other LangChain provider (Cohere, Mistral, Vertex AI, Bedrock, Azure) by installing its package, plus Claude Code and Codex through their official SDKs
• Multiple input types: pandas or Polars DataFrame and Series, list, dict
• Structured output: Pydantic validation; a rejected answer goes back to the model with the error
• Resilience: Automatic retry with exponential backoff, and periodic checkpoints (batch_size + checkpoint_path) to resume long runs
• Performance: Parallel processing that halves workers on rate limits, configurable rate limiting
• Web search: Tavily or Exa, per field or per group of fields, with conditional fields (condition, depends_on)
• Tracking: Token usage, search credits and throughput metrics

Per-Field Configuration

Set field-specific prompts and search parameters using json_schema_extra:

from pydantic import BaseModel, Field

class DrugInfo(BaseModel):
    # Field with the default prompt
    active_ingredient: str = Field(description="Active ingredient of the drug")

    # Field with a custom prompt (replaces the base prompt)
    rare_disease: str = Field(
        description="Rare disease classification",
        json_schema_extra={
            "prompt": "Search Orphanet (orpha.net). Analyze: {texto}"
        }
    )

    # Field with an additional prompt (appended to the base prompt)
    conitec_assessment: str = Field(
        description="CONITEC assessment",
        json_schema_extra={
            "prompt_append": "Search ONLY the CONITEC website (gov.br/conitec)."
        }
    )

    # Field with custom search parameters
    clinical_trials: str = Field(
        description="Relevant clinical trials",
        json_schema_extra={
            "prompt_append": "Search for recent clinical trials.",
            "search_depth": "advanced",
            "max_results": 10
        }
    )

# Requires search_per_field=True
result = dataframeit(
    df,
    DrugInfo,
    "Analyze the drug: {texto}",
    use_search=True,
    search_per_field=True,
)

The full list of per-field options (including max_search_calls, condition and depends_on) is in the web search guide.
