How Reliable Is AI-Generated Python for Simple Excel Tasks?

This is a perfectly reasonable way to get started. Ask the AI to add detailed comments, explain each block for a beginner, and describe the assumptions it is making. You can then compare its explanations with Python and library documentation instead of treating the generated code as automatically correct.

Modern AI tools are usually quite capable with simple, clearly specified tasks such as filtering spreadsheet data, copying values, and performing basic calculations. They become less dependable as the requirements get more complicated, so expect to test, revise, and possibly rewrite parts of the solution. Matching a few sample outputs is a good start, but also test edge cases such as blank cells, duplicate records, unexpected formats, and division by zero.

For a small, self-contained job like moving data between Excel files, AI-generated code will often work reasonably well. The bigger concern is that it may be unnecessarily complicated or inefficient. Reading through every line and testing the results is important, because when something eventually breaks, you’ll need enough understanding to diagnose it yourself.

Whether this is a good approach depends on your goal. If Python is just a tool for automating spreadsheet work, using AI to draft a basic script is reasonable as long as you validate the output. If you want to learn programming, don’t stop at getting a working answer: ask the assistant to guide you through the implementation, explain the reasoning, and point you toward relevant documentation and tutorials. You remain responsible for checking the final calculations and handling any sensitive data safely.

Be aware that generated code can be over-engineered. It may introduce lots of abstractions or separate components that make a straightforward script harder to follow. The code can function correctly while still being poor teaching material, so ask for a simpler, beginner-friendly version and have it explain alternative approaches and their trade-offs.
