I can work with a wide range of data sources, including Excel workbooks (.xlsx), CSV files, SQL database dumps/connection strings, Google Sheets, and raw data files.

Yes! I can handle data cleaning, fixing broken formulas, resolving date formatting issues, removing duplicates, and structuring your raw dataset before building any queries or dashboards.
