Code Interpreter brings real code execution into ChatGPT. Upload a CSV, ask a question about your data, and receive not just an answer but the actual Python code that computed it, complete with charts, tables, and downloadable output files. No local development environment needed.
Whether you are a data analyst processing quarterly reports, a student solving statistics homework, or a business user who needs a quick chart for a presentation, Code Interpreter handles the technical complexity while you describe what you need in plain English.
ChatGPT Code Interpreter executes Python code in a secure sandboxed environment directly within the chat interface. Upload files in formats like CSV, Excel, JSON, PDF, and images to have them analyzed, transformed, or visualized. Code Interpreter writes Python scripts using libraries like pandas, matplotlib, seaborn, numpy, and scipy, runs them in real time, and displays results inline. It handles data analysis, statistical computations, chart generation, file format conversion, image processing, and mathematical problem-solving with computational accuracy rather than text-based approximation.
A full Python execution environment accessible through natural language conversation.
Upload a spreadsheet, database export, or CSV file and ask questions about your data in natural language. Code Interpreter writes and runs pandas code to filter, aggregate, pivot, merge, and transform your data. It handles missing values, detects outliers, calculates statistical measures, and identifies trends without requiring you to write a single line of code. The results are presented as clean tables and summaries with the underlying Python code visible for transparency and reproducibility.
Business analysts use Code Interpreter to process quarterly sales data, calculate year-over-year growth rates, and identify regional performance patterns. Marketing teams analyze campaign metrics across channels. Financial teams process transaction logs and generate reconciliation reports. The tool handles datasets with hundreds of thousands of rows efficiently, making it practical for real-world business data volumes rather than just toy examples.
Describe the chart you want and Code Interpreter creates it. Bar charts, line graphs, scatter plots, heatmaps, histograms, box plots, pie charts, and multi-panel figures are all supported through Python's matplotlib, seaborn, and plotly libraries. The generated visualizations are publication-quality with proper axis labels, legends, color schemes, and formatting that you can download directly from the chat.
The natural language interface means you do not need to know matplotlib syntax. Say "Create a bar chart showing monthly revenue by region with a trend line" and Code Interpreter handles the implementation details. If the first result is not quite right, describe the adjustment: "Make the bars wider, use a blue color palette, and add data labels on top." Iterating on visualizations is as simple as having a conversation, as documented in the official Code Interpreter overview.
Code Interpreter accepts a wide range of file formats for processing. Upload CSV, Excel (XLSX), JSON, PDF, TXT, PNG, JPG, GIF, SVG, Python (.py), SQL, HTML, and XML files. The system reads file contents, understands the structure, and performs operations you request. Convert an Excel file to CSV, extract text from a PDF, resize a batch of images, parse JSON into a structured table, or clean and reformat a messy data file.
File output works in reverse: Code Interpreter generates downloadable files as part of its processing. Ask it to clean your data and export a new CSV, create a chart and download it as a high-resolution PNG, or process a set of images and return them as a ZIP archive. This end-to-end file processing capability makes Code Interpreter a practical tool for real workflows where the goal is a tangible output file, not just a text answer.
Code Interpreter runs Python in a secure sandbox that is isolated from the internet, other users, and your local machine. This isolation means uploaded data stays within the sandbox during the session and is not accessible to external systems. The environment includes popular Python libraries: pandas, numpy, scipy, matplotlib, seaborn, plotly, scikit-learn, Pillow, openpyxl, beautifulsoup4, and many more.
The sandbox executes code in real time, showing both the code and its output inline in the conversation. If the code produces an error, ChatGPT reads the error message, diagnoses the problem, and retries with a corrected version automatically. This self-correcting loop means even complex multi-step computations succeed without manual debugging. The environment persists within a session, so variables and processed data carry over between messages, allowing you to build up analysis incrementally. Security practices align with NIST cybersecurity guidelines for sandboxed execution environments.

Code Interpreter is a built-in ChatGPT feature that executes Python code in a secure sandboxed environment directly within the chat interface. It processes uploaded files, performs data analysis with pandas and numpy, generates charts with matplotlib and seaborn, handles file format conversions, and runs computational tasks. You describe what you need in natural language and Code Interpreter writes, runs, and shows the results of the Python code that accomplishes it.
Code Interpreter accepts CSV, Excel (XLSX), JSON, PDF, TXT, PNG, JPG, GIF, SVG, Python scripts (.py), SQL files, HTML, and XML, among other common formats. It can read, analyze, transform, and generate files in these formats. Output files are downloadable directly from the chat, including generated charts (PNG, SVG), processed data (CSV, Excel), and converted documents.
Code Interpreter runs in a sandboxed environment isolated from the internet and other users. Uploaded files are processed within this secure sandbox and are not permanently stored after the session ends. The environment follows ChatGPT's SOC 2 Type II security standards with AES-256 encryption at rest and TLS 1.3 in transit. Enterprise and Business plans provide additional data isolation controls and admin oversight for sensitive data processing.
Yes. Code Interpreter generates professional-quality visualizations using Python libraries including matplotlib, seaborn, and plotly. Supported chart types include bar charts, line graphs, scatter plots, heatmaps, histograms, box plots, pie charts, and multi-panel figures. Describe the visualization you want in natural language and Code Interpreter produces it with proper labels, legends, and formatting. Charts are displayed inline and downloadable as image files.
Regular ChatGPT generates text responses based on pattern matching from training data. Code Interpreter actually executes Python code, producing verifiable computational results. It processes real data files with mathematical precision, generates visual outputs, and creates downloadable files. This makes it appropriate for tasks where accuracy matters: data analysis, statistical calculations, financial computations, and scientific processing rather than general text-based conversations.
