How to get FieldSet fields in Apex Dynamically (fieldset name is not static)

String fieldSetName = 'Account_FieldSet';
String ObjectName = 'Account';

I wanted get list of all fields from this fieldset.

I know if fieldset name is hardcoded in the apex then following syntax works -


But here main issue is Object name and fieldset name will come at runtime.

How to get FieldSet fields in Apex Dynamically (fieldset name is not static)

Here is the method I came up with lots of trial and errors -

public static List<Schema.FieldSetMember> readFieldSet(String fieldSetName, String ObjectName)
    Map<String, Schema.SObjectType> GlobalDescribeMap = Schema.getGlobalDescribe(); 
    Schema.SObjectType SObjectTypeObj = GlobalDescribeMap.get(ObjectName);
    Schema.DescribeSObjectResult DescribeSObjectResultObj = SObjectTypeObj.getDescribe();

    //system.debug('====>' + DescribeSObjectResultObj.FieldSets.getMap().get(fieldSetName));

    Schema.FieldSet fieldSetObj = DescribeSObjectResultObj.FieldSets.getMap().get(fieldSetName);

    //List<Schema.FieldSetMember> fieldSetMemberList =  fieldSetObj.getFields();
    //system.debug('fieldSetMemberList ====>' + fieldSetMemberList);  
    return fieldSetObj.getFields(); 

You can use result as follows -

List<Schema.FieldSetMember> fieldSetMemberList =  Util.readFieldSet('Account_FieldSet','Account');
for(Schema.FieldSetMember fieldSetMemberObj : fieldSetMemberList)
    system.debug('API Name ====>' + fieldSetMemberObj.getFieldPath()); //api name
    system.debug('Label ====>' + fieldSetMemberObj.getLabel());
    system.debug('Required ====>' + fieldSetMemberObj.getRequired());
    system.debug('DbRequired ====>' + fieldSetMemberObj.getDbRequired());
    system.debug('Type ====>' + fieldSetMemberObj.getType());   //type - STRING,PICKLIST

There is a slightly shorter way to deal with this. The following method returns null if the field set is undefined, or a list of field set members otherwise:

public static List<Schema.FieldSetMember> getFieldSetMembers(String objectTypeName,
        String fieldSetName) {
    DescribeSObjectResult[] describes = Schema.describeSObjects(new String[] {

    if (describes != null && describes.size() > 0) {
        // There should only be the one match for the one object type name
        Schema.FieldSet fs = describes[0].fieldSets.getMap().get(fieldSetName);

        return fs.fields;
    } else {
        return null;

I hope this is the code you are looking. Dynamic mapping with field set to clone list of records.

// test1 is the filled set on contact

List<Schema.FieldSetMember> schemaset=;

 // clisttoUpdate: fill this list with the records for which you wanted to clone by using dynamic soql with filed set
List<contact> clisttoUpdate=new List<contact>();
//to store mapped records to insert at the end
 List<account> acc=new list<account>();

List<contact> ListWithData=new List<contact>();
List<contact> listForClone=new List<contact>();

for(integer i=0;i<ListWithData.size();i++){


   contact cloneRec=new contact();

   for(integer a=0;a<schemaset.size();a++){
          cloneRec.get(schemaset[a].getFieldPath()) =clisttoUpdate[i].get(schemaset[a].getFieldPath())




insert listForClone;
