How to use Llamma index and Langchain to do the same?

I am wondering how can I use llamaindex and langchain to achieve the same thing done in the course.

I have an excel about places and I want to filter place according to query. The excel has some columns with specific info but mostly it’s very wordy description which basically contains all the attributes about the place. Is it a good idea to break it down into simpler sentences and augment name of the place at start?
