How to convert report in to PDF in Salesforce Apex class?

Hi Tanu,

It is not possible to convert report into PDF, but  in place of this you can create visualforce page same as report and schedule the visualforce page by using the code:
public class EmailReport implements Schedulable {
public void execute(SchedulableContext sc) {
List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();
Messaging.EmailFileAttachment attach = new Messaging.EmailFileAttachment();
attach.setContentType('application/pdf');
attach.setFileName('Report.pdf');
pagereference Pg = Page.PDFPage;
Blob body = pg.getcontentAsPdf();
attach.Body = body;
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
mail.setToAddresses(new String[] { '[email protected]' });
mail.setSubject('PDF Generation');
mail.setHtmlBody('PFA');
mail.setFileAttachments(new Messaging.EmailFileAttachment[] { attach });
mails.add(mail);

if(!mails.isEmpty()) {
Messaging.SendEmail(mails);
}
}
