Excel Logic to SQL Translation | Dataford Interview Questions

Your question is Excel Logic to SQL Translation. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

Context

Analysts often rely on Excel functions like VLOOKUP, SUMIF, IF, and COUNTIF to clean data and answer quick business questions. In SQL roles, interviewers want to know whether you can translate that spreadsheet thinking into scalable database queries.

Core Question

What is your favorite Excel function, and how has it saved you time? Then explain how you would recreate the same type of logic in SQL.

Your answer should cover:

What the Excel function does and why it is useful
A concrete example of a repetitive task it simplifies
The closest SQL equivalent or pattern
When SQL is a better choice than Excel for the same task

Scope Guidance

Keep the discussion practical rather than theoretical. The interviewer is not looking for a list of Excel functions; they want to hear how you think about data manipulation, how spreadsheet operations map to SQL, and where each tool is most appropriate.
