Question

How we can get value from a cell in google spreadsheet?

I have row and column index from ROW() and COLUMN() - 1.

In other words what is t

Answer 1

Say the row number is in A1, and the column number is in A2, any of these should work:

=OFFSET(A1;A1-1;A2-1)
=INDIRECT("R"&A1&"C"&A2)
=INDEX(A1:400000;A1;A2)

Answer 2

To do so use indirect() as such:

=indirect("'PAGE ASD'!"&A2&A3)

where A2 contains the letters to column like "D" or "AA" where A3 contains the number to row like "2" or "35" and the page you are calling the data from is called "PAGE ASD"
