Individual skill

spreadsheet-data-cleaning

Produces spreadsheet-native data cleaning formulas and operations. Generates exact TRIM, CLEAN, TEXT, SUBSTITUTE formulas for text issues, IF/IFERROR wrappers for null handling, COUNTIF for duplicate detection, and a cleaning sequence with before/after column strategy. Use when the user needs to clean data using spreadsheet formulas rather than external tools. Do NOT use for a full data cleaning protocol across any tool (use data-cleaning-protocol), setting up validation rules (use data-validation-setup), or auditing a spreadsheet model (use spreadsheet-model-audit).
