FAQ
What files do you need to start the cleaning process?
I need your source dataset (CSV, Excel, JSON, or TXT) and a clear brief of what needs to be fixed or standardized (e.g., "remove duplicates in column X, format all dates to YYYY-MM-DD").
How do you handle very large files that crash standard software?
I handle them effortlessly. By writing highly optimized Python scripts with Pandas and NumPy, I can process large datasets efficiently without running into local performance or memory bottlenecks.
Will you share the code used to clean the data?
Yes, absolutely! I will deliver the final cleaned data file along with the clean, well-commented Python script (.py file) so you can reuse it whenever you get fresh data.
I don't have Python installed. How can I run the script in the future?
No problem at all. I can provide a simple walkthrough showing you how to run the script with a single click using a free cloud environment like Google Colab.
Can you build an API or automate this cleaning process weekly?
Yes! If you need this script to run automatically or as a web service, I can wrap the data pipeline inside a custom Flask API. Please message me directly to get a tailored custom offer for this.
