I will clean and organize messy excel or CSV data
Data analyst
About this Gig
I can clean, organize, and preprocess your dataset so it is structured, consistent, and ready for analysis, reporting, or further processing.
I work with Excel, CSV, and Python/Pandas depending on the requirements of your project.
I can help with:
- Removing duplicate records
- Handling missing or blank values
- Fixing inconsistent text, dates, and number formats
- Correcting data types and column names
- Removing unnecessary rows or columns
- Splitting or combining columns
- Sorting, filtering, and restructuring data
- Merging multiple Excel or CSV files
- Standardizing categories and values
- Preparing datasets for analysis or machine learning
You will receive a clean and well-organized CSV or Excel file. Python/Pandas code can also be included depending on the selected package.
Every dataset is different, so larger files or complex cleaning rules may require a custom offer.
Please contact me before ordering if you have multiple files, a large dataset, complex requirements, or need urgent delivery.

FAQ
What file formats can you work with?
I primarily work with Excel (.xlsx, .xls) and CSV files. If you have another file format, please message me before ordering and I will check whether I can work with it.
What kind of data cleaning can you do?
I can remove duplicates, handle missing values, standardize text and dates, correct formatting and data types, restructure columns, remove unnecessary data, merge files, and perform other common data-cleaning tasks.
Can you work with large datasets?
Yes, but the price and delivery time depend on the number of rows, columns, files, and the complexity of the cleaning rules. Please contact me before ordering if your dataset exceeds the package limits.
How will you handle missing values?
It depends on your data and requirements. Missing values can be removed, replaced, filled using an appropriate method, or left unchanged. I will follow your instructions and can discuss the best option with you before starting.
Can you merge several CSV or Excel files into one dataset?
Yes. I can combine multiple files or sheets when they have compatible structures. For multiple or complex files, please send me a sample or description before ordering.
Should I contact you before placing an order?
For a simple dataset that clearly fits a package, you can order directly. For large datasets, multiple files, unusual formatting, complex transformations, or urgent work, please contact me first so I can recommend the correct package.
