FAQ
What kind of data cleaning issues can you fix?
I handle duplicate removal, missing/null values, inconsistent formatting (dates, names, addresses), typos, incorrect data types, merging datasets and standardizing values across columns.
What file formats do you work with?
I work with Excel (.xlsx/.xls), CSV, Google Sheets and can also convert between formats as part of the cleanup.
How large of a dataset can you handle?
I can handle datasets ranging from a few hundred rows to tens of thousands of rows. For very large or complex datasets, message me first so I can confirm turnaround and pricing.
Will you use formulas/macros or clean everything manually?
I use a combination of Excel formulas, macros, and manual review to ensure both speed and accuracy, critical fixes are always manually verified.
How do you handle missing or incomplete data?
Depending on your preference, I can remove incomplete rows, fill gaps using logical rules, flag them for your review, or leave them as-is; just let me know your preference.
Can you also analyze the data after cleaning?
Basic summaries (totals, counts, simple pivot tables) can be included on request. For in-depth analysis or dashboards, that would be a separate custom offer.
How fast can you deliver a cleaned dataset?
Small datasets can be done within 24 hours. Larger or more complex datasets typically take 2–4 days. Rush delivery is available as an add-on.
Can I send a sample of my data before ordering?
Yes, message me with a sample and a description of the issues and I'll confirm scope, pricing, and turnaround before you order.
