Messy Excel or CSV files slowing you down?


I will clean and organize your existing tabular data.


I can remove duplicates using an agreed key, trim spaces, standardize text and dates, split or combine columns, and merge tables with matching columns or a reliable shared ID.


You receive:

- Your cleaned Excel or CSV file

- A short summary of changes and row counts

- A list of missing or ambiguous values needing your decision


Packages cover 100 / 1,000 / 3,000 total input rows across 1 / 3 / 5 tables and 3 / 5 / 8 agreed rules. One rule is one operation on a column, or one duplicate/merge rule.


Please send a small sample and your desired result before ordering so I can confirm the package.


I preserve an original copy and do not invent missing facts. Manual research, PDF extraction, fuzzy matching, complex formulas, macros, dashboards and reusable software are separate projects.


A revision corrects the agreed rules using the original files. New files or new rules change the scope.
