Mixed CSV Data Cleaning

I have several CSV/Excel files containing a mix of text and numerical fields that need to be cleaned and standardized. The goal is to turn these raw exports into analysis-ready datasets by removing duplicates, fixing inconsistent formats, handling missing values, and flagging any obvious outliers. Once the work is done I’ll need the cleaned files returned in the same spreadsheet format along with a brief changelog so I can see exactly what was adjusted.

Please let me know your expected turnaround time and any questions you have about the structure of the files.
