À propos de moi
I help clean, organize, and prepare Excel data for reporting and dashboards.
Many spreadsheets become hard to use due to inconsistent text, mixed date formats, missing values, and poor structure. I fix these issues using Power Query so data becomes accurate, reliable, and analysis-ready.
What I can help with:
• Cleaning messy Excel files (text, dates, nulls)
• Standardizing categories like city or product names
• Preparing data for reports or Power BI
• Creating simple Excel or Power BI dashboards
I work step by step and avoid quick fixes that break data later.
