Operational Troubleshooting

Import errors

ModuleNotFoundError: wolfxl._rust

• Ensure package install succeeded.
• Verify Python environment is the one you execute from.

Legacy import failures (excelbench_rust)

• Install/update shim package if legacy paths are still used.
• Prefer migrating runtime imports to wolfxl/wolfxl._rust.

Save failures

• Confirm write or modify mode is used before save().
• Check filesystem permissions and target path validity.

Data mismatch reports
