These data will not have any real use, I just want them to be shown to users because this will add a feature that similar programs like mine do not have at all and users of my app requested it from me
What advantage is a useless feature? Similar programs omit this functionality because it is absurd. No one will waste time scrolling painfully slowly amongst 150 million cells in a grid to find data of interest, even the person(s) who asked for it.
Far better would be to implement a filter or search function that would locate data of interest without labouring to possibly also display tens of millions of unwanted cells.
