Presenting results in the web page

Problem: Long csv files causes the web page to crash.
Solution: Click to generate the results and automatically starts the download.

I thought it was better to implement it in another way, the flow remains the same, but only a "sample" of the data is displayed. And the CSV download button doesn't hang, and it's very fast to generate and download.
