I use OpenOffice, and LibreOffice, tools along those lines since most Microsoft tools charge for everything.

I even found one for ios called Collabora, which is similar to Google sheets but has some rough edges to its flow but considering it's foss it works ok.

you wouldn't believe the number of places that won't buy any ERP/CRM and just do their whole business through crappy spreadsheets. it's still better than paper I guess
