About this Gig

Clean CSV or Excel data with clear rules and a reusable Python script.


I remove exact duplicates, trim whitespace, standardize dates and text, and split or combine columns according to your instructions. One item means one data row; row limits are the total across all files. Each file may contain up to 10 columns.


Basic: 1 file, 100 rows, 3 rules, 1-day delivery.

Standard: up to 3 files, 5000 total rows, 5 rules, 2-day delivery.

Premium: up to 5 files, 10000 total rows, 10 rules, 3-day delivery, plus a validation report.


Every package includes cleaned files, a reusable Python script and a change summary. Original files are preserved. Revisions correct the agreed rules; new files or rules need a separate scope.


Share an anonymized sample, cleanup rules and desired output. Missing values are handled only as you instruct. Fuzzy matching, manual research, complex formulas and workbook redesign require a custom quote. I communicate in writing and check the output before delivery.
