Does anyone have a a free and offline LibreOffice (or Excel) spreadsheet to track trades of multiple altcoins? Absolutely no google spreadsheets, data pulls from online sources, or macros of any kind for security and privacy.

I'm mostly interested in tracking NAV of my portfolio, and will update it weekly or monthly.

Also, I'm considering starting a trade diary on the forum. Are there others doing the same, would like to see where to post it and what to do - and perhaps more importantly, what not to do and show.
