How to add a column checkbox in a datagriview with data of csv file using c#

I want to add a new column with checkbox, my data is from a csv file and showed it in a datagridview with this code:

DataTable dtDataSource = new DataTable();

            string[] fileContent = File.ReadAllLines(\data.csv);

            if (fileContent.Count() > 0)
            {
                //Create data table columns
                dtDataSource.Columns.Add("ID);
                dtDataSource.Columns.Add("Data 1");
                dtDataSource.Columns.Add("Data 2");
                dtDataSource.Columns.Add("Status");

                //Add row data dynamically
                for (int i = 1; i < fileContent.Count(); i++)
                {
                    string[] rowData = fileContent[i].Split(',');
                    dtDataSource.Rows.Add(rowData);


                }
                if (dtDataSource != null)
                {
                    dataGridView1.DataSource = dtDataSource;

                }
            }

But also I need to validate if checkbox is checked, the column ¨Status¨, their value must be changed by 1 or if is it unchecked the value must be 0 in every row of datagridview.

Example:

ID,Data1,Data2,Status,checkbox
1,aaa,bbb,0,✓
2,ccc,ddd,1,(unchecked)
3,eee,fff,1,(unchecked)

When you click the buttom save, the csv file should be looks like this:

ID,Data1,Data2,Status
1,aaa,bbb,1
2,ccc,ddd,0
3,eee,fff,0

What I should do? Any ideas? CSV file is a little difficult for me.

Thank you!
