DataOlllo is a desktop application for preparing and analyzing local data files. Open CSV data, select the rows and columns you need, split or merge files, and save repeatable workflows without writing code.
It lets you open large CSV files locally, explore, clean, and analyze your data, then save and repeat your workflow. File capacity depends on your computer, the dataset, and the operation you run.
DataOlllo brings together no-code operations, AI intelligence, and workflow automation into one seamless experience.

Why DataOlllo Is Different
⚡ Fast & Powerful
Choose a preview, select relevant columns, or split a source file before working with more data. These approaches help keep a task manageable; processing time and memory use depend on the file and operation.
🔒 Local-First Privacy
Use local file operations to prepare data on your computer. Optional cloud AI has different data-sharing implications from local processing; review the privacy policy before handling sensitive information.
🖱️ No-Code, Button-Click Simplicity
You don’t need to write any code. Cleaning, filtering, joining, transforming, and visualizing your data can all be done through simple buttons and clear controls.
🤖 Integrated AI
The optional AI assistant helps you request operations in natural language. Review generated steps and results before relying on them. Available providers include cloud services and local Ollama; choose the provider that fits your data-handling requirements.
🔁 End-to-End Automation
Every action you take can be saved as part of a workflow. Reuse it anytime to instantly repeat your entire process with one click.
