This traceability is critical for verifying data analysis outcomes, as simple chat logs lack the code and execution context needed to replicate or audit the AI's reasoning process. The ipynb format's cell-based structure, which stores markdown, code, and outputs in JSON, enables complete reconstruction of the analytical workflow.", "body_md": "# Why ipynb is a perfect format for saving AI data analysis conversations\n\nFive years ago, having a computer program where you could simply load your data and ask questions about it was only a dream. And honestly, not many people even dreamed about it. In 2026, this is a reality. The AI data analyst exists. Today, there are many implementations of AI data analysts. Some are open source, some are proprietary, and some are built in-house by companies for their own needs.\n\nIn this article, I want to share my experience from building an AI data analyst. More specifically, I want to explain why I chose the `ipynb`\n\nformat — the Jupyter Notebook file format — to store conversations with an AI data analyst. I want to show how traceability and replication of conversation are achieved with this format.\n\n## What is AI data analyst?\n\nLet's start by looking closer at what an AI data analyst is. We are familiar with chat interfaces. We send a prompt and get a response. In the classic chat approach, we get a response based on chat's internal knowledge. When we ask chat about specific questions, for example about our business, chat probably will not provide a correct answer, because it doesn't have knowledge about it. It will respond with something, a hallucination.\n\nThe next step towards AI data analyst is to provide the AI with knowledge. It can be done in many ways. There are Retrieval Augmented Generation (RAG) systems that index and search documents for LLMs, enabling them to provide correct answers. In this approach, the interesting parts of documents are included as context for LLM. The other approach is to allow for AI to use programming skills - basically, write a short script, execute it, and read the output. Using such a skill, AI can, for example, generate code to read our Excel file, execute it, and print the spreadsheet header so the data structure is known. The code generated by the LLM can also be used to query the database. LLM has an available environment where it can send SQL queries, execute them, and check results. The last approach is AI with internet access, which can connect to APIs or scrape web pages directly to get the required information.\n\nWhen the proper context is provided or constructed for AI, it can analyze data to provide insights. Sometimes, when the relationships between data are obvious, the LLM can provide insights directly just by looking into the context. For example, it can easily spot maximum or minimum values in the list of numbers. When the data is complex, AI can use code to provide insights or create data presentations with dashboards, visualizations, or reports.\n\nBasically, the AI data analyst is a chat with access to data and the skill to create, execute, and output the code. For storing basic chat messages, we can use a simple list of strings and save it as a text file. For an AI data analyst, we have prompts, text responses, code responses, and code execution results.\n\n## What is `*.ipynb`\n\nformat?\n\nThe `ipynb`\n\nformat is for storing Jupyter notebooks. A Jupyter notebook is a document with a list of cells. Each cell is a Markdown text or code. Markdown cells are displayed to the user. Code cells are executed, and the results are displayed below the cell. The result can be almost anything: text, HTML, JavaScript, images. The `ipynb`\n\nstores information about the cell list, and for each cell, it saves its source (markdown or code) and output (for code cells). The `ipynb`\n\nis basically a JSON format. The saved values in `ipynb`\n\ncan be reloaded in Jupyter and displayed.\n\n## Why simple chat history is not enough\n\nA conversation with an AI data analyst is different from a normal chat. In a normal chat, we usually only care about the question and the answer. In data analysis, this is not enough.\n\nWe need to know what data was used, what code was generated, what the execution result was, and how the final answer was created. Without this information, it is very hard to verify the analysis later. It is also hard to repeat the same steps or debug the result when something looks wrong.\n\nThis is why saving only text messages is not enough. The full conversation should include prompts, explanations, code, outputs, charts, tables. The `ipynb`\n\nformat already supports all of these elements.\n\n## Traceability: every step is saved\n\nOne of the biggest benefits of the `ipynb`\n\nformat is traceability. In data analysis, the final answer is usually not enough. We also want to know how this answer was created. What was the original question? What code was generated? What data was loaded? What was printed as output?\n\nWith the `ipynb`\n\nformat, all those steps can be saved in one file. The user prompt can be stored as a Markdown cell. The code generated by AI can be stored as a code cell. The result of code execution can be stored as output under the cell. The final explanation can again be stored as a Markdown cell. This creates a clear history of the whole analysis process.\n\n## Replication: analysis can be executed again\n\nAnother important benefit of the `ipynb`\n\nformat is replication. In data analysis, we often want to run the same analysis again. Maybe the data was updated. Maybe we want to check if the result is correct. Maybe another person wants to review our work.\n\nWhen the conversation is saved as a notebook, the code is not only stored as text. It can also be executed again. This is a big difference compared to a normal chat history. In a chat history, we can read what happened, but we cannot easily rerun the analysis. In a notebook, we can open the file, inspect the code, and execute the cells again.\n\nThis makes the AI data analyst more transparent. The answer is not a magic response from the model. The answer is connected with code, data, and execution results. Anyone with access to the same data and environment can repeat the steps and verify the result.\n\nWhat is more, the `ipynb`\n\nnotebook can be easily converted to Python script. The conversation might be a good starting point for script creation. What is more, the `ipynb`\n\ncan be easily converted into HTML and served as static web page.\n\nThe conversation with AI data analyst:\n\nThe same conversation displayed as Python notebook:\n\n## Summary\n\nThe `ipynb`\n\nformat is a very good fit for saving AI data analysis conversations. It can store user prompts, AI explanations, generated code, execution results, charts, tables, errors, corrections, and metadata in one file.\n\nThis is exactly what we need for an AI data analyst. The conversation is not only text. It is a full analytical process. We need to know what was asked, what code was created, what was executed, what output was returned, and how the final answer was produced.\n\nThe notebook format gives us traceability, replication, and easy publishing. We can review the analysis step by step, rerun the code, share the notebook with others, or convert it to HTML and publish it as a web page. This makes `ipynb`\n\na natural choice for me to store conversations with an AI data analyst.\n\n## AI Data Analyst on Your Computer\n\nUse MLJAR Studio to explore data, find insights, and create reports with AI.
