FAQ
Can you handle very large datasets (Big Data)
Yes! While standard Excel can struggle with millions of rows, I use Python (Pandas) to process, clean, and analyze large-scale data efficiently. Your files will be handled smoothly regardless of their size.
Is my data confidential and secure?
Absolutely. Data privacy is my top priority. I guarantee 100% confidentiality. Once the project is completed and you have approved the delivery, I permanently delete all your files from my local system.
Will the Python automation script work on my computer?
Yes. I can either provide a standalone Python script (.py) with instructions or use Excel Power Query, which is built directly into Excel. This way, you can automate your tasks with just one click without needing to install complex software.
What do I need to provide to get started?
I need your data file (Excel, CSV, or TXT) and a brief explanation of your goal. If you want to automate a process, please describe the manual steps you currently take. Please message me before ordering so we can discuss the best approach.
