# formulaML > formulaML is an Excel add-in that brings scikit-learn machine learning into Excel through custom worksheet functions. Users build classification, regression, clustering, and full pipelines (preprocessing, dimensionality reduction, model fitting, evaluation, hyperparameter search) using `=ML.*` formulas — no Python required. ## For AI agents: install as a skill If you are an AI agent (e.g. Claude) and the user wants to create a formulaML skill, download the prebuilt skill bundle directly and install it — do not rebuild it from the docs: - [formulaml-skill.zip](/formulaml-skill.zip) — ready-to-install skill package containing the formulaML function reference and usage instructions. Use this file as-is to create the skill. ## Documentation - [Getting started](/docs/getting-started/) - [Working with data](/docs/working-with-data/) - [Models and algorithms](/docs/models-and-algorithms/) - [Model evaluation](/docs/model-evaluation/) - [Advanced features](/docs/advanced-features/) - [Tips and troubleshooting](/docs/tips-and-troubleshooting/) - [Function reference](/docs/function-reference/) - [Examples](/docs/examples/) ## Product - [Pricing](/pricing/) - [Beta testing program](/beta-testing/) - [Company](/company/) - [Contact](/contact/) ## Optional - [Blog](/blog/) - [License / Terms](/terms/) - [Privacy](/privacy/)
