When is it preferable to use a program or script instead of an Excel spreadsheet?

Question

Programs and scripts scale and handle data structures that spreadsheets cannot easily represent or process efficiently. Relevant concepts: performance limits (memory, CPU, and row/column caps), data dimensionality (spreadsheets are fundamentally 2‑D grids), reproducibility and automation (scripts can be rerun reliably), and human readability (spreadsheets are often better for ad‑hoc inspection).

Step‑by‑step reasoning through each option:
a. When handling large amounts of data — True. Modern Excel is limited by memory and practical performance; even though current Excel supports 1,048,576 rows × 16,384 columns, operations on millions of rows are slow or impossible in many workflows. Programs (e.g., Python with pandas, R, databases) stream, chunk, or use optimized storage and can handle far larger datasets efficiently. Therefore a program/script is preferable.

b. When trying to communicate with non‑programmers — False. Spreadsheets are generally more accessible to non‑programmers because the grid, cell formulas, and charts are directly viewable. Using a script would usually make communication harder unless you wrap results in a user‑friendly report.

c. When dealing with array dimensions greater than 2 — True. Spreadsheets are inherently two‑dimensional (rows and columns). Representing 3D or higher tensors in Excel is awkward and error‑prone; scripts and languages with native multi‑dimensional array support (NumPy, R arrays, MATLAB) are designed for this and are preferable.

d. When the relationships between results and the raw data need to be most transparently communicated — False. Spreadsheets often make relationships explicit because formulas are visible next to data; scripts can be transparent too when well documented, but for direct, immediate transparency to non‑programmers, a spreadsheet usually wins.

Conclusion: Options a and c are correct. This matches the provided answer: a. When handling large amounts of data, and c. When dealing with array dimensions greater than 2.
