FAQ
What file formats do you accept?
CSV, Excel (.xlsx, .xls), JSON, and Google Sheets exports. If you have something else, message me first.
What if my dataset is larger than 100k rows?
Order the Premium package or contact me for a custom quote. I can handle large files efficiently with pandas chunking.
Will I be able to re-run the cleaning myself?
Yes. Standard and Premium packages include a fully commented Python script you can run on any new data.
Is my data safe?
Absolutely. I work only with files you share, don't store them, and delete everything after delivery. I can sign an NDA if needed.
