À propos de ce service
Is your Excel or CSV data messy, duplicated, or spread across multiple files?
I will clean, merge, and automate your data processing to make it accurate, structured, and easy to use.
Messy spreadsheets waste time and lead to errors. Instead of manual work, I use efficient methods to clean and organize your data quickly and reliably.

- Clean and standardize columns (names, emails, countries, etc.)
- Merge multiple files into one structured dataset
- Validate and organize your data for easy use
I review every file carefully and adapt the solution to your specific needs.

FAQ
What files do you accept?
I work with CSV and Excel (XLSX) files. If you’re not sure about your file format, feel free to message me first.
What kind of cleaning do you perform?
• Remove duplicate rows. • Clean inconsistent formatting. • Standardize columns and values. • Merge multiple Excel or CSV files into one structured dataset. • Fix inconsistent capitalization. • Trim extra spaces. • Handle missing values safely, and ensure required columns are present.
What if my file has missing columns or missing data?
I handle missing values safely. If required columns are missing, I will notify you before proceeding.
Will you modify my original file?
No. I always keep the original file unchanged and deliver a clean version as a new file.
Do you provide the source code?
This gig delivers clean data files only. Source code can be provided as a separate service upon request.
How do you handle duplicate records?
I identify duplicates based on your preferred field (e.g., email, ID, name). If inconsistencies exist, I can flag them for review instead of blindly deleting data.
Can you merge multiple Excel or CSV files?
Yes. I can merge structured or semi-structured files into one clean dataset while maintaining consistency and avoiding duplication.
Is my data confidential?
Absolutely. Your files are handled privately and used only for the agreed project.
What file formats do you work with?
Excel (.xlsx, .xls), CSV, and similar structured data formats.
What if my data is very messy?
Send a message first. I’ll review the file and confirm the best approach before starting.
