There are times you need Excel, and then there are times you just want to do some quick calculations. Tinysheet is a great app for the latter.
With Tinysheet you get 2 columns and 10 rows in the spreadsheet which are not resizable. The site works very much like a spreadsheet, allowing you to do some basic calculations on your data. When you’re done, you can share the sheet with others via a link, embed code, or on Twitter.
Tinysheet is also a nice way to introduce spreadsheets to students without all of the bells and whistles available in Excel or Google Sheets.
