About Barbaro

I help companies clean, organize, and automate data in Excel, Google Sheets, and Power Query.

I work with CSV files, messy databases, operational reports, pivot tables, reconciliations, and time-consuming manual processes.

My approach is practical: deliver clean data, clear templates, actionable reports, and simple automations to reduce errors and repetitive work.

I can help you with:
- Data cleaning and normalization
- Excel and Google Sheets automation
- Power Query
- Pivot tables
- Dashboards and operational reporting
- CSV file consolidation
- Extracting and organizing information from PDFs
- Data preparation for CRM, ERP, or analysis

Ideal for short, urgent projects or tasks that you need to resolve quickly and well.
