Google Sheet / Excel - Use formula as the cell row for parent formula?

Question

E.g Cell M25 has the value 10:

=Init_Data!K CELL(M25)

would say:

=Init_Data!K10

I've Googled hard for this but it's such a weird one to explain.

Thanks

Answer 1

INDIRECT is Volaitle and in this instance you can use INDEX instead which is not:

=INDEX(Init_Data!$K:$K,M25)

Answer 2

=INDIRECT ("Init_Data!K"&M25)
