Spreadsheet cleanup with an editable file and QA logHiroyuki Watanabe
Turn one inconsistent spreadsheet into a clear, usable workbook. The $175 package covers one XLSX or CSV file with up to 1,000 rows and 20 columns.
You receive:
• An untouched copy of the original data.
• A cleaned, editable XLSX with agreed date, text and number formats.
• Exact duplicate rows and missing values flagged for review; no records silently deleted or invented.
• A QA and change log with remaining exceptions.
• One revision within the agreed scope.
Before booking, message a short description and the approximate file size. We will confirm cleanup rules, data handling, the exact delivery time and Contra funding before work starts. Delivery is normally within one day after those prerequisites and usable source data are available.
AI and scripts are used. Please agree on AI permission before sharing source data; an anonymized sample can help define the scope.
Accounting or tax advice, reconstructing missing facts, macros, external data collection and production-system changes are outside this package. Complex or larger files need separate scoping.
The portfolio example is an original fictional demonstration, not client work.
