Sobre mim
I clean up messy Excel and Google Sheets data and automate the work around it.
What I do:
• Data cleaning: duplicates, broken formats, mixed dates, split or merged columns
• Google Sheets automation: forms, emails and other tools feed your sheet, with an AI step that sorts or summarizes
• Reusable fixes, so next month's file cleans itself (Power Query or Apps Script)
Based in Germany. I handle your data under GDPR and sign an NDA on request.
Send me your file or a sample before you order. I'll tell you what I'd fix and what it costs.
