You will get I will clean, format and organize your Excel or CSV data file
Project details
You have data that is messy, inconsistent, or just hard to work with — and you need it clean, structured, and ready to use. I help businesses and researchers transform raw Excel or CSV files into well-organized, error-free spreadsheets.
With an Engineering Physics background and hands-on experience in data processing and quality analysis, I go beyond simple formatting. I check for duplicates, null values, structural inconsistencies, and format errors — and deliver a file that actually makes sense.
