How can I use some fix values in a field in all 100 records (e.g. India in all records)

I want to create data with 100 records (Rows) with id, first_name, Last_name, Country.
India should be fixed value for all 100 rows

You can use the Template field type to output a constant value for any field. You can also filter the Country field type so that only locations in India are returned.
