How synchronize tasks which updated through Execl VB

Summary:

We have updated the tasks through excel VB and those tasks
not synchronized with peer tasks.

For example we have tasks as below

Row 1) 104 manufacturing -> This is the peer task
sub tasks are
104.101 Test1
104.102 Test2
Row 2) 105
Row 3) 106

Now we have added the task under the 104 peer task
104.103 and given level as 2. But system is created at
row no 4 as 104.103.
Not synchronized under the 104 peer task

How synchronize these kinds of tasks, as we have many tasks crated through VB.
