Creating Excel in Visualforce Page.

Create a visualforce page and add the content type attribute in the <apex:page>

<apex:page standardController="Opportunity" extensions="OpportunityReport_Extn" showHeader="true" sidebar="true" cache="true" contenttype="application/vnd.ms-excel#Opportunity_report.xls">
  <apex:pageBlock >
       <apex:pageblockTable value="{!generateReport}" var="oppty" id="tbl1">
           <apex:column value="{!oppty.Name}"/>
           <apex:column value="{!oppty.Id}"/>
           <apex:column value="{!oppty.StageName}"/>
           <apex:column value="{!oppty.Closedate}"/>
           <apex:column value="{!oppty.Type}" />
       </apex:pageblockTable>    
   </apex:pageBlock>
</apex:page>

In this page I have used controller, below is the code for that.

public class OpportunityReport_Extn {
    public List <Opportunity> getgenerateReport()
    {
       query = 'select Closedate,Name,Type,StageName,Id from Opportunity';    
        try
        {
            List<Opportunity> opplist = database.query(query);
            return opplist;          
        }
        catch (QueryException e)
        {
            ApexPages.addMessages(e);
            return Null;
        }      
   }
}

The above code will generate the Excel sheet.

Note: If your excel sheet contains some extra data, such us Months and month picklist, for that if you have used <apex:form> tag, remove that form tag in the visualforce page.

How to update an AccountTeamMember Via DataLoader

If you want to update the Account Team Member in Salesforce Via Dataloader

we have to use Account Share Object.

Account Share object will have data of AccountTeamMemeber and Owner of the Account.

While Updating we have to skip the owner data and we have to update only the AccountTeamMember data.

Below is the screen shot for Account Team Member Present in the Account.

For this Account when we extract the AccountShare Object from Dataloader, it has 2 records.

In the RowCause field you can identify, whether it is Team or Owner. you cannot update the data for Owner. Team Data can be updated.

so using data loader you can update the Team Data, which will automatically update the Access of Account Team Member data.
