FAQ
What file formats do you work with?
CSV, XLSX and JSON files, plus data from PostgreSQL databases. Cleaned data is delivered in the same format or in any other of these on request.
Is my data safe? Will the original file be changed?
Your data is used only for your order and is never shared. The original file is never overwritten: you always get a separate cleaned copy.
My file is large or very messy. Can you still help?
Yes. Message me before ordering and send a small sample. I will check the data and send a custom offer with a fair price and deadline.
