FAQ
What files can you clean?
I work with supplied XLSX and CSV tables. If your file has complex formulas, merged layouts or multiple unrelated sheets, please send a redacted sample before ordering.
What counts as a duplicate?
We agree the rule first: exact full-row matches or a specific key such as an ID. Conflicting records are flagged. I do not guess which value is correct.
Will you fill missing data?
This package cleans existing data. Missing values are flagged; web research and data enrichment are not included.
What will I receive?
A cleaned XLSX or CSV, plus brief change notes. I preserve the original source data and check row counts, duplicate rules and the output format.
