FAQ
What file formats do you accept?
I work with Google Sheets and CSV files. If you have a different format please message me first and I will let you know if I can help.
Will you keep my data confidential?
Absolutely. Your data is only used to complete your order and is never shared with anyone.
What makes this different from basic data cleaning?
This service includes a full systematic audit of every column — not just cleaning but diagnosing and documenting every data quality issue found. You receive a detailed written report alongside the cleaned dataset.
Can you handle datasets larger than 8,000 rows?
Yes. Message me before ordering with your dataset size and I will create a custom offer.
How do you ensure accuracy on large datasets?
I work column by column using systematic formulas and reconciliation checks rather than manual cell-by-cell editing. Every change is documented.
What if I face a problem after accepting the delivery?
Your satisfaction matters. If you notice any issue after delivery please message me immediately and I will resolve it within the revision limit of your package. I want every client to be happy with the result.
