Not sure what to do with my website

So finally after months thinking about it, I finally released a website idea I had been thinking about for a while, https://www.bongos-analytics.com/

It is basically a place that allows for an Excel file upload and it can produce things like Histogram, Correlation chart, text clustering using K-Means and a word cloud.

However, I really have no idea what to do with it. I added some amazon product link but that's just meh. Also, I am paying 2 dollars per day for google traffic giving me now around 150 clicks per day (1.5k clicks per 14 days according to Google) and again, no idea what to do with that traffic...

So, any suggestions? roastings? Is it even worth maintaining?

​

Thanks
