I’ve made a lot of google docs and excel spreadsheets for myself.
They all automatically pull and update price data/historic data from API and present what I want in a nice, clear form.
I made many of those for: lp stores, mining, industry, trading, character selling, well… basically everything.
PM me what you need for your private and customized spreadsheet and how much are you willing to pay for it. However, if it’s below 1b then I’m afraid I’m not interested as it requires probably at least a couple of hours of my work.
If you prefer some public mining, industry or trading tools I can recommend Evernus and IPH.
Best regards
