Have a spreadsheet with inconsistent dates, duplicate rows or missing values?
I have room for one small cleanup project today, September 6 (Japan time): $175 for one file up to 1,000 rows and 20 columns. You get an editable XLSX, the preserved original data, a QA/change log and one revision.
I use AI and scripts. Message me on Contra with a short brief so we can agree on scope, data handling and the exact delivery time before funding or sharing source data.
The service includes a clearly labeled fictional workbook example:

Migration Data Validation — SQL & Python Demo
This synthetic example shows why matching row counts and totals is not enough to validate a data migration.
Both datasets contain 10 rows totaling USD55.00, yet row-level checks identify a missing record, a duplicate key, and a changed amount.
Includes executable Python validation, sample datasets, a discrepancy report, and Snowflake SQL templates.
Python checks were executed locally. The Snowflake SQL has not been executed against a warehouse.
Demonstration using synthetic data, not client work.
