What types of data formats can this skill process?

The skill can handle a wide variety of formats including CSV, JSON, and direct database extractions, transforming them into analysis-ready structures.

How does the skill handle missing data?

It implements industry best practices for missing value handling, such as mean/median imputation, forward-filling, or specific removal logic based on your requirements.

Does it provide feedback on the cleaning process?

Absolutely. After execution, the skill provides a summary of all changes made, including the number of records cleaned, imputed, or transformed.

Is this skill suitable for machine learning workflows?

Yes, it is specifically designed to prepare raw data for ML by ensuring proper scaling, encoding, and data quality validation.

Do I need to write the Python code for the ETL process?

No, the skill automatically generates the necessary Python code based on your description of the data and the desired end state.
