Protection of Interactive Excel Spread Sheet on the Web

Protection of Interactive Excel Spread Sheet on the Web

Protection of Interactive Excel Spread Sheet on the Web

(OP)
Does anyone know of a way to be able to make an Excel worksheet visible on a web page, but at the same time not having to unlock and unprotect the formulas and code in each of the cells?

Does this require the use of a server or "dummy" excel web page?

RE: Protection of Interactive Excel Spread Sheet on the Web

In EXCEL you can SAVE FILE AS > HTML and check "add operability".
That will save the file as an HTML document.

However in order for someone to operate the spreadsheet in a web browser they must use IE and the microsoft web components (downloadable I think from microsoft).

Theoretically it should work that way (I have never done it, as I use Javascript for that purpose).

I believe that the end user will need a licensed copy of Excel on their machine for the spreadsheet to actually work

Good Luck

RE: Protection of Interactive Excel Spread Sheet on the Web

(OP)
I am familar with the save as html capability - however it does not work unless you unlock and unprotect all of the cells - thereby allowing the user to see the coding, and allowing the user to save the speadsheet on his system.

Anyone have any other thoughts?

RE: Protection of Interactive Excel Spread Sheet on the Web

i am pretty certain that the only way you can get web-operability plus code security is to keep your calculation routine (as a script file) on the web server and use a javascript in your HTML web page (that is on the user's computer via his/her web browser) and  to reference the script by way of a button on your web page.

of course you have to ask your ISP if he'll allow you to allow users to execute programs on his server.

i don't think a simple spreadsheet solution exists.

if you find one.... PLEASE post your findings here.

regards.
