Fictional survey workbook cleanup (AI-assisted)

Fictional survey workbook cleanup (AI-assisted)
An independent spreadsheet demonstration using 40 fictional survey records. This is not client work, production data or evidence of business results.
The editable workbook preserves the source sheet and creates a separate cleaned view. It normalizes 39 nonblank dates and category spacing, converts numeric scores, leaves three missing values blank, and flags two exact duplicate rows without deleting records.
A QA and change-log sheet reconciles 40 raw rows against 40 cleaned rows and records transformation rules and missing-field locations. The exported workbook passed an archive-integrity check and a formula-error scan.
Created with JavaScript, AI assistance and the Artifact Tool spreadsheet runtime. No client information or external assets were used. The image shows part of the cleaned sheet; editable XLSX and three sheet previews are prepared. Paid work starts only after agreement on scope, AI permission, data handling, delivery time and platform funding.
