基于 Excel 单元格值引用 Excel 列

Question

In Excel how can I create a cell function which does the following...

1. If cell C1 contains the value 6, I want cell B1 to be the contents of cell M1,
2. If cell C1 contains the value 7, I want cell B1 to be the contents of cell N1

and so forth, increasing by one column (M,N,O...) at a time.

I've tried with the functions INDEX, IF, MATCH and, LOOKUP.

Answer 1

Use INDEX and simple math:

=INDEX(1:1,C1+7)
