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.
