About this Gig

Messy exports can hide duplicate rows, inconsistent dates and IDs that lose their leading zeroes.


I will clean a values-only Excel or CSV table using agreed rules and return:

- a cleaned XLSX and CSV;

- your original data, preserved;

- a change log showing what changed;

- a review file for ambiguous values and excluded duplicates;

- a short handover explaining formats and remaining questions.


The work can cover spacing, agreed label mappings, explicit date and number formats, and exact duplicates. Missing values are flagged, not invented. The gallery shows an original demonstration with fictional data, not client results.


Please message me with a redacted sample and your rules before ordering. Packages apply to flat, values-only tables with one clear record per row. They exclude OCR, scraping, macros, live integrations, fuzzy matching, formula repair and sensitive personal data.


AI-assisted tools support the work. The output is tailored and checked against the agreed rules. I cannot accept work that requires an exclusively human workflow. All communication and payment stay on Fiverr.
