Lookup and Merge Helper
Combine data from two tables with the right lookup.
Updated June 2026
The prompt
Help me look up or merge data in {{tool}} where I need to {{task}}. Recommend the right function (VLOOKUP, INDEX MATCH, XLOOKUP, or a join), explain why, handle common pitfalls (missing matches, duplicates, exact versus approximate, data type mismatches), provide the formula or steps, and show how to handle not-found cases gracefully. Note the most common reason a lookup returns wrong or error results and how to avoid it. Columns: {{columns}}.
