FAQ
What file formats do you support?
I support CSV, Excel, TSV, JSON and XML files. If you have another structured data format, feel free to contact me before ordering.
What counts as duplicate removal?
Duplicate removal identifies records that appear more than once and removes or flags them based on the structure of your data. If duplicates require business-specific rules, please contact me before ordering.
Will you modify my original file?
No. Your original file will remain unchanged. I will deliver a cleaned copy.
Can you handle large datasets?
Yes. If your file contains a very large number of rows or multiple files, please contact me before ordering so I can recommend the correct package.
