Hi,

In short, currently my data looks like this:

A1 B1
2343
x234
x345
4567
x567
x678
x484
x444
3453
x564
x345
x543

etc.
While I would need it like this:

A1 B1 C1
2343 x234 1
x345 2
4567 x567 1
x678 2
x484 3
x444 4
3453 x564 1
x345 2
x543 3

I hope it's self explanatory and makes sense. Could somebody please
help me how to do this? I've got couple of thousands of these records,
everything is ready, it's a matter of one time conversion only.

Thank you.
