ExcelEverywhere and SpreadsheetConverter are the same programs, so a license key for SpreadsheetConverter works for ExcelEverywhere and vice versa.

Converts an Excel spreadsheet into an ASP or ASP.NET-page. The web page looks like the spreadsheet and calculates
like the original spreadsheet.
SpreadsheetConverter to HTML/JavaScript is included, so you can generate
plain HTML-pages too.
When you buy you get:


Free updates, e.g. from 3.4 to 3.5.

Free upgrades for 6 month, e.g. from 3.5 to 4.0
Free email support for at least 6 month. Currently, we give
free email support to everyone, regardless on when you purchased.
However, we cannot promise we will do that forever.

30 day no questions asked money back guarantee


The price of SpreadsheetConverter is per developer, i.e. you need
one license per computer where SpreadsheetConverter is installed.
There are no additional costs; there are no royalties to pay when you
publish the resulting web pages on your web server.
