I don't see any ads on mobile. How does this generate revenue?

This blows my mind. I thought excel had "save as -> html". Whether it does or not, nice work finding this niche

Try to save simple Excel file as HTML, and see how many files Excel generates. Also, Excel-generated HTML files are very hard to embed anywhere, too much garbag

Save as HTML in all the MS Office products are absolutely hideous. The code they generate is awful.
