Skill instructions
Clean Data Clean messy data in the active sheet or a specified range. Environment - If running inside Excel (Office Add-in / Office JS): Use Office JS directly (Excel.run(async (context) = {...})). Read via range.values, write helper-column formulas via range.formulas = [["=TRIM(A2)"]]. The in-place vs helper-column decision still applies. - If operating on a standalone .xlsx file: Use Python/openpyxl. Workflow Step 1: Scope - If a range is given (e.g. A1:F200), use it - Otherwise use the full used range of the active sheet - Profile each column: detect its dominant type (text / number / date) and identify outliers Step 2: Detect issues | Issue | What to look for | |---|---| | Whitespace | leading/trailing spaces, double spaces | | Casing | inconsistent casing in categorical columns (usa / USA / Usa) | | Number-as-text | numeric values stored as text; stray $, ,, % in number cells | | Dates | mixed formats in the same column (3/8/26, 2026-03-08, March 8 2026) | | Duplicates | exact-dup
