Hi  S S,
 
# AccountDataExcel.page

<apex:page controller="AccountDataController" contentType="application/vnd.ms-excel#AccountTable.xls" showHeader="false" standardStylesheets="false">
  <apex:pageBlock >
    <apex:dataTable value="{!accounts}" var="account">
      <apex:column value="{!account.id}"/>
      <apex:column value="{!account.name}"/>
      <apex:column value="{!account.description}"/>
      <apex:column value="{!account.SLA__c}"/>
      <apex:column value="{!account.Active__c}"/>
   </apex:dataTable>
 </apex:pageBlock>
</apex:page>
 
public with sharing class AccountDataController {
  //constructor
  public AccountDataController() {
  }

  //list of accounts
  public List<Account> accounts {
    get {
      if(accounts != null) {
        return accounts;
      } else {
        accounts = [Select Id, name, Active__c, SLA__c, Description from Account limit 10];
        return accounts;
      }
    }
    set;
  }
}

We are now ready to add the “Export to Excel” button to the AccountData.page as follows:
public PageReference exportToExcel() {
   return Page.AccountDataExcel;
 }

Thanks

HI SS,

you need to create 2 vf page with  same controller .On first you create Account data table with expot button like this-
1.AccountDataTable page-
<apex:page controller="AccountDataController" tabStyle="Account">
<apex:form >
  <apex:pageBlock title="Account Data Table">
  <apex:commandButton value="Export"  action="{!exportAll}"/>
    <apex:pageBlockTable value="{!accounts}" var="account">
      <apex:column value="{!account.id}"/>
      <apex:column value="{!account.name}"/>
      <apex:column value="{!account.description}"/>
      <apex:column value="{!account.SLA__c}"/>
      <apex:column value="{!account.Active__c}"/>
    </apex:pageBlockTable>
  </apex:pageBlock>
  </apex:form>
</apex:page>
2.Excel file page-
<apex:page controller="AccountDataController" contentType="application/vnd.ms-excel#AccountTable.xls" showHeader="false" standardStylesheets="false">
  <apex:pageBlock >
    <apex:dataTable value="{!accounts}" var="account">
      <apex:column value="{!account.id}"/>
      <apex:column value="{!account.name}"/>
      <apex:column value="{!account.description}"/>
      <apex:column value="{!account.SLA__c}"/>
      <apex:column value="{!account.Active__c}"/>
   </apex:dataTable>
 </apex:pageBlock>
</apex:page>
Controller-
public with sharing class AccountDataController {
  //constructor
  public AccountDataController() {

      if(accounts != null) {
        return accounts;
