FAQ
Q1: What file formats do you accept?
A: I primarily work with CSV, Excel (.xlsx, .xls), and JSON files. If you have data in another format like SQL or Google Sheets, please message me first.
Q2: Will you provide the Python source code?
A: Yes! The Python script (Jupyter Notebook or .py file) using Pandas is included in the Standard and Premium packages. For the Basic package, it can be added as a Gig Extra.
Q3: How do you handle missing or null values?
A: I use statistical methods like Mean, Median, or Mode imputation, or fill them with a constant value (like 0) based on the nature of your data and your specific requirements.
Q4: Can you handle large datasets with millions of rows?
A: Absolutely. Since I use Python and NumPy, I can efficiently process large-scale data that Excel might struggle to handle. Please contact me for custom pricing on very large datasets.
Q5: Is my data safe with you?
A: Yes, data privacy is my top priority. Your files will only be used for the cleaning process and will be deleted from my system once the order is completed and approved.
Q6: What if I need a specific type of data formatting?
A: I can perform custom formatting, such as splitting columns, merging datasets, fixing date-time formats, and standardizing text (Lower/Upper case). Just let me know your requirements!
