I'm using a simple Euclidian distance formula `sqrt((a-b)^2 + (c-d)^2)`

and I have more than 60,000 data in my each excel sheet. Instead of dragging mouse (which is very inconvenient for this large number of data) how can I define the range of records? For example my formula looks like -

```
=SQRT((H2-J2)^2+(I2-K2)^2)
```

And also, to popolate the result in 60000 rows, where should I write the formula?
