C # Oledb truncating column excel

I'm doing a select in an excel where I have an observation column (open text). The problem is that on some lines it truncates the contents of that column by bringing only one part.

try
{
    conn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Path.Combine(Environment.ExpandEnvironmentVariables("%userprofile%"), "Downloads") + @"\RelPosicaoGeralPendencias.xls;Extended Properties='Excel 8.0;HDR=Yes;'");
    conn.Open();

    cmd = new OleDbCommand("SELECT * FROM [RelPosicaoGeralPendencias$]", conn);

    reader = cmd.ExecuteReader();

    listaPendenciaNassau = new List<Pendencia>();

    while (reader.Read())
    {
        if (!(reader[6] is DBNull))
        {
            Pendencia pendencia = new Pendencia();

            pendencia.Contrato = reader[2] is DBNull ? null : reader[2].ToString().Replace("'", "").Trim();
            pendencia.Tipo = reader[3] is DBNull ? null : reader[3].ToString().Trim();
            pendencia.PendenciaNivel = reader[5] is DBNull ? null : reader[5].ToString().Trim();
            pendencia.PendenciaId = reader[6] is DBNull ? 0 : Convert.ToInt32(reader[6]);
            pendencia.PendenciaTipo = reader[8] is DBNull ? null : reader[8].ToString().Trim();
            pendencia.GarantiaDescricao = reader[9] is DBNull ? null : reader[9].ToString().Trim();
            pendencia.Observacao = reader[10] is DBNull ? null : reader[10].ToString().Replace("'", "").Trim();
        }
    }
}
