FAQ
What format should I send my raw data in?
I accept CSV, Excel, JSON, and plain text files. If you are dealing with raw API feeds or custom log files, please send a small sample in our chat first so I can review the structure.
Do you only clean financial market data?
No, I can clean, structure, and normalize databases for e-commerce, healthcare, or any other industry.
What exactly will I receive upon delivery?
You will receive the fully commented MySQL (.sql) script containing all the data cleaning and structuring logic, alongside the final processed data exported as a clean CSV or Excel file.
Can you handle large datasets with millions of rows?
Yes! MySQL is built for high-volume data. For extremely large files, I utilize Python scripts to optimize the extraction and loading process into the database to ensure accuracy and speed.
I also need this data visualized. Can you help?
Absolutely. I hold a Microsoft and MSME-backed certification in data analytics and am fully equipped to build interactive Power BI dashboards from your cleaned database as a custom extra.
Will my proprietary trading or business data remain private?
100%. I maintain strict confidentiality with all client files. Your raw data and the final outputs are completely deleted from my local systems immediately upon final order approval.
Do I need to provide the database schema?
No, you do not have to. If you purchase the Premium package (or add the Schema Diagram extra), I will design the optimal relational structure between the staging and production tables for you.
