I have a table in excel with the following data:

```
      A       B      C
1    Name    Age    Fare
2    Owen    22     7.25
3    Lionel  36     0
4    John    38     71.3
5    Gladys  5      8
6    Mark    12     0

```

My problem is I want to locate the row numbers where the value for column C is zero (in my example, it will give the 3rd and 6th row). I'll appreciate any kind of help since the data I got has 1000 rows and locating the row number with a zero value for column C is a bit time-consuming. Thank you!
