I have a file with a start and end number, like below

```
Start,end,code
43786,67883,avb
200,400,add
12,14,adf

```

I need to however rewrite this so that all the numbers in the range between start and end are written with their code:

```
43786,Avb
43787,avb
43788,avb
43789,avb

```

Till the last 67883,avb in that range and continue to

```
200,add
201,add
202,add 

```
