Refer below code. 

Document doc = [Select Id,body from Document where id = '0152w000000NCIp'];
String stringBody = doc.body.tostring();
list<String> filelines = stringBody.split('\n');
list<Account> accstoInsert = new list<Account>();
for (Integer i=1;i<filelines.size();i++)
{
    list<String> columnValues = new list<String>();
    columnValues = filelines[i].split(',');
    system.debug('->'+columnValues);
    Account a = new Account();
    a.Name = columnValues[0];
    a.SLASerialNumber__c = columnValues[1];
    accstoInsert.add(a);
}
if(accstoInsert.size()>0){
    insert accstoInsert;
}

You can mention Document query in Start method and in execute method can perform rest of the logic. Make sure to change the Object and its fields you want to insert. 

Thanks,

Hi Prince, 

Can you please elaborate on what you want to achieve ?  Do you want to read a CSV file and based on row values formulate a custom object record ?

Regards,
Ashvin

It is working perfectly well
but not able to pass date datatype
a.Startdate__c = date.valueof(columnValues[1]); or a.Start__datec = date.parse(columnValues[1]);
