The short answer
PandasAI (23,681 stars) is the leading open-source tool for conversational data analysis: ask questions in plain English (or Chinese), and it generates and runs the pandas/SQL code for you. It supports CSV, Excel, SQL databases, and data lakes, and works with most LLMs including local ones.
What PandasAI actually does
import pandas as pd
from pandasai import SmartDataframe
df = SmartDataframe(pd.read_csv("sales.csv"), config={"llm": your_llm})
df.chat("Which region had the highest revenue growth in Q3?")
# -> runs the analysis, prints the answer and the code it used
Key capabilities:
- Natural language to code: "show me top 5 products by margin" becomes working pandas.
- Multiple data sources: CSV, Excel, SQL, Parquet, data lakes.
- Explainability: it shows you the generated code - audit before you trust.
- Local LLM support: run with Ollama for fully private analysis of sensitive business data.
Real performance notes (2026)
In practical use, PandasAI handles straightforward aggregation, filtering, and plotting reliably. It struggles with: ambiguous column names, multi-step logic requiring domain judgment, and very large datasets where naive queries generate inefficient code. Budget 10-20% of your time to correct or refine generated queries.
Streamlit pairing - the 2026 combo
The most popular pattern is PandasAI inside a Streamlit (45,451 stars) app: a simple web UI where non-technical colleagues type questions against your company data. One afternoon of work, and your team stops emailing you for pivot tables.
FAQ
Is PandasAI free? The core is open source (free); the hosted PandasAI platform has paid tiers.
Does it work with Excel files? Yes - Excel, CSV, SQL, and more are supported natively.
