Excel Formula Explainer & Builder
Example session with this skill installed
I need a formula to find the price in column C for a product name in A2, looking at a table in Sheet2 from A:C, but only if the status in column B is 'In Stock'.
- Read your context and instructions
- Compiled the excel formula explainer
FORMULA
=INDEX(Sheet2!C:C, MATCH(1, (Sheet2!A:A=A2)*(Sheet2!B:B="In Stock"), 0))
HOW IT WORKS
INDEX returns the value from the price column (C). MATCH(1,...) looks for a row where two conditions are TRUE: the name matches A2 and the status is "In Stock".
EXAMPLE
A2: "Widget"
Sheet2: Widget | In Stock | $10
Result: $10
EXCEL vs. GOOGLE SHEETS:
Works in both. In older Excel versions, press Ctrl+Shift+Enter.
COMMON MISTAKE
Forgetting that both ranges must be the same size (e.g., A:A and B:B).

About this skill
The problem
Writing complex spreadsheet formulas is error-prone and time-consuming. Most users know what they want to achieve but struggle with nested logic, correct syntax, and debugging broken references.
What it does
- Converts plain-English descriptions into ready-to-use Excel and Google Sheets formulas.
- Deconstructs existing, complex formulas into simple, piece-by-piece explanations.
- Identifies and fixes errors in broken formulas provided by the user.
- Provides comparative syntax for functions that differ between Excel and Google Sheets.
- Generates realistic data examples to verify formula logic before implementation.
Frameworks & tools
Microsoft Excel (including Office 365 dynamic arrays) and Google Sheets.
Why this beats prompting it yourself
Standard LLMs often provide formulas without explaining the "why," leading to maintenance headaches when data ranges change. This skill enforces a structured breakdown of every argument and proactively warns you about common pitfalls like absolute vs. relative reference errors.
Use cases
- Creating advanced lookups using XLOOKUP or INDEX/MATCH across multiple criteria.
- Building complex conditional logic for automated reporting and dashboards.
- Cleaning messy data using text manipulation and dynamic array functions.
- Debugging inherited spreadsheets with massive, undocumented formulas.
Known limitations
Does not write VBA macros or Google Apps Script. Focuses strictly on native cell formulas and dynamic arrays.
