Pandas to DuckDB Converter — Examples & 2025 Guide

Efficiently moving data from Pandas DataFrames to DuckDB tables is an increasingly vital skill for data scientists and analysts working with both Python and SQL tools. This workflow unlocks in-memory analytics, rapid prototyping, and the full power of SQL on your Pandas data. Traditionally, translating between these frameworks meant writing glue code and navigating syntax hurdles. That’s where AI2sql platform steps in—it effortlessly turns your intent into ready-to-execute SQL, even automating the conversion of Pandas data to DuckDB tables, all without manual SQL coding.

This guide will walk you through why the Pandas to DuckDB pathway is essential, practical methods for conversion, and—most importantly—how AI2sql removes complexity, letting you focus on analysis and insights rather than technical integration.

Why Convert Pandas DataFrames to DuckDB?

• Enable advanced SQL analytics directly on your Pandas data.

• Leverage performance: In-memory DuckDB querying can be faster for complex aggregations.

• No more translation pain: Use DuckDB’s powerful SQL without manual export/import steps.

How to Convert Pandas to DuckDB: Methods

There are multiple approaches to bring Pandas data into DuckDB tables. Here’s how the process works using SQL (thanks to DuckDB’s Python integration):

1. Register Pandas DataFrame as a DuckDB view

2. Create a persistent DuckDB table from your DataFrame

3. Query DataFrames with pure SQL in DuckDB

Real-World Examples: Pandas to DuckDB Conversion

1. Registering a Pandas DataFrame as a DuckDB View

-- Registers the DataFrame (assume df is a Pandas DataFrame)
INSTALL pandas;
LOAD pandas;
CREATE VIEW my_view AS SELECT * FROM df;

2. Creating a DuckDB Table from a Pandas DataFrame

CREATE TABLE my_table AS SELECT * FROM df;

3. Querying a Registered Pandas DataFrame in DuckDB

SELECT city, AVG(sales) FROM df GROUP BY city;
