Having an Embedded Spreadsheet Is Handy
Spreadsheets are used everywhere. There's no doubt that a spreadsheet application like Excel is one of the most popular business applications in the world. It is so easy that anyone can use it, yet it is so powerful that it enables experts in different fields to “code” their business logic in the simplest way possible.
A standalone spreadsheet is great for personal use, but it's hard to share. That is why Google Sheets was born. With Google Sheets, it becomes much easier to share and collaborate. But people want more — they want to have the sheet directly on their web pages; whether it is a web application, a wiki page, or a company website.
