Two other alternatives are Sharepoint Excel Services ($7000)

and SpreadsheetConverter to ASP & ASP.NET ($149 per developer). It
generates an ASP.NET page from an Excel spreadsheet with formulas. All
the calculations will work on the ASP.NET-web page.

One thing is for sure - if you put a workbook on the web you might as well
stick your formulas on a billboard.

| Hello,
|
| We have a number of Excel documents containing formulas and calculations
| based on a number of input cells. We want to make these calculations
| available on our website, but it's very important that the formulas
| remain secret.
|
| I figured that to be sure that malicious users won't be able to get the
| formulas involved, they have to be calculated on a server.
|
| As an absolutely last resort, we could recreate the logic in a proper
| ASP.NET web site, but this is very tedious and makes updating the
| calculations a nightmare. Preferably, one would only have to update the
| Excel sheet to make the web calculation similarly updated.
|
| Do anyone have suggestions on how we can accomplish this?
|
| I've taken a look at a couple different "spreadsheet to web converters",
| but none of them seem particularly robust and reliable.
