def Form1_Load(self, sender, e):
    try:
        with open('./data.json') as f:
            data = json.load(f)
        AddWarningMessage(str(data))
        for i in data:
            self.dataGridView1.Rows.Add(*i)
    except:

            data.append([])
            for j in range(len(self.dataGridView1.Rows[i].Cells)):
                x = self.dataGridView1.Rows[i].Cells[j].Value
                if j == 3:
