When should I use index match?

I'm curious about the optimal scenarios for utilizing the index match function in Excel. Can you elaborate on when it's most beneficial to apply this feature? Perhaps there are specific tasks or projects where index match shines, and I'd like to know more about those instances. Additionally, I'm wondering if there are any drawbacks or limitations to using index match that I should be aware of before incorporating it into my workflow. Clarifying these points would greatly assist me in deciding when and how to best utilize this tool.
