FAQ
Do I need to provide the database access?
No. You can simply send me your data in a CSV, Excel, or SQL export file. I will perform the cleaning and send the corrected file back to you. If you need the specific SQL scripts I used, I can provide those as well!
Can you handle very large datasets?
Yes! Because I use SQL scripts rather than manual editing, I can process thousands of rows quickly and accurately. If your dataset is very large, please message me for a custom quote.
What if my data has special characters or messy formatting?
That is my specialty! I use Regex (Regular Expressions) and string manipulation to remove symbols (like $, #, %), fix broken dates, and standardize text so your data is ready for analysis.
