If you're looking to transition from Excel-based test case management to a more efficient test automation framework, there are several great options depending on your needs.

One solid choice is FitNesse, a wiki-based test framework that allows testers to create and manage test cases directly through a web interface. Instead of dealing with complex Excel macros and XML generation, testers can write test cases in simple tables, making it more readable and collaborative.

Alternatively, Robot Framework is another great option. It's keyword-driven and supports easy integration with Selenium and API testing.

For more flexibility, you might also consider TestNG (if you're using Java) or PyTest (for Python-based testing). Both offer powerful reporting, test organization, and parallel execution capabilities.

Would you mind sharing more details on your tech stack? That way, I can suggest something that fits your needs even better.
