The driver becomes a living entity, a malevolent spirit. You try the "Oracle ODBC Driver" (deprecated). You try the "ODBC Driver for Oracle" from Microsoft (old, buggy). You finally find the "Oracle Instant Client" (the holy grail), but you forget to set the TNS_ADMIN environment variable. The machine rejects you.

You spend the next hour in a state of existential dread, trying different versions of the driver. Do you need the 32-bit driver or the 64-bit driver? (Spoiler: Your OS is 64-bit, but Excel is 32-bit, so you need the 32-bit driver—good luck finding that in the documentation.) driver odbc oracle

You witness it negotiate encryption (thank you, modern security standards) so that your CEO’s salary data isn’t broadcast in plain text across the office Wi-Fi.

When you enable tracing, the driver becomes a wiretap on the conversation between your app and the database. You can see every single byte sent and received. It is voyeuristic and educational. You finally find the "Oracle Instant Client" (the
