FAQ
1. What file formats do you accept?
I accept CSV, XLSX, and XLS files. Contact me before ordering if your data is stored in another format.
2. What types of data cleaning are included?
The service can remove exact duplicates, blank rows, unnecessary spaces, and inconsistent column headers. It can also combine compatible files.
3. How do you identify duplicate records?
By default, I remove rows that are completely identical. If duplicates must be identified using specific columns, such as email, phone number, or customer ID, please provide those instructions.
4. Can you combine multiple CSV or Excel files?
Yes. The files must have compatible columns and a similar structure. The number of files included depends on the selected package.
5. Will my formulas, formatting, and macros be preserved?
This service focuses on data tables. Complex formulas, macros, charts, pivot tables, and advanced formatting may not be preserved. Contact me before ordering if your workbook contains these elements.
6. Can you clean more than 150,000 rows?
Yes, but please contact me before ordering so I can review the file size, structure, and processing requirements.
7. Do you manually correct missing or inaccurate information?
No. The standard service does not include manual research, data entry, or verification of missing information. Custom rules can be reviewed before ordering.
8. Is my data kept confidential?
Your files will be used only to complete the order. Please remove passwords, financial information, or other sensitive data that is not required for the project.
9. What information do you need before starting?
Please provide the original files, preferred output format, columns used to identify duplicates, and any special cleaning or merging rules.
10. Do you provide the Python script or source code?
No. The standard deliverable includes the cleaned data file and, depending on the package, a processing report. Source code is not included.
