How secure is SpreadsheetConverter for HTML, can anyone see my formulas?
Since the formulas are converted into JavaScript and the JavaScript formulas are in plain text on the web page, anyone who selects View Source in the browser can see the resulting JavaScript. In a couple of hours, a person knowledgeable in JavaScript will be able to reverse-engineer the original spreadsheet. Therefore, if you need to keep the formulas secret, SpreadsheetConverter for HTML is not for you. The products SpreadsheetConverter for Java/JSP and SpreadsheetConverter for ASP&ASP.NET solves this problem, since the formulas will never leave the web server. Microsoft has a solution that only works for Internet Explorer called Script Encoder. The solution is not totally secure, but makes reverse engineering much more difficult. It is a simple command-line tool that enables script designers to encode their final script so that Web hosts and Web clients cannot view or modify their source.
