This is in regards to an article written by Scott Mitchell posted on this site. His article "Creating Excel Spreadsheets with Office Web Components" describes using web components to create a new excel worksheet using asp on the web. I was wondering if anyone could point me to documentation or help regarding using the office web components to open an existing excel file and changing the value of cells from the web. I have a heavily customized excel model that I would like to "web enable" so that users can change specific cell values and view the results in different cells. In a nutshell I would like to use an asp page to have a user input values on an asp page witch would export that data to an existing excel file on the web server, and then return the values of specific cells back to the web. Any help would be appreciated
