Turn messy Excel or CSV files into a clean, reliable dataset ready for analysis, reporting, or import.

Included:

Clean inconsistent dates, numbers, spaces, and capitalization

Remove duplicates using agreed matching rules

Merge multiple sheets or files with compatible columns

Identify missing or invalid values

Deliver the cleaned Excel/CSV file plus a short change summary

Starter scope ($25): up to 3 files, 5,000 total rows, one output table, and one revision. Larger or complex files will be quoted before work begins.

Please send the source files, desired output format, and any rules for duplicates or required columns. I work through written communication and start after the scope and acceptance criteria are clear.

No unpaid samples. If the data is sensitive, please use anonymized data or an agreed secure method.
