对一行中的每个第 n 个单元格进行无限求和

Question

I am making a spreadsheet for my football (or soccer) team, and tracking how much each player has paid and whether they're in credit/debt so I'm calculating the balance in Sheet1 per game and then in Sheet2 calculating the total balance.

The formula I am trying to do is, in Sheet2 trying to SUM each value under the "Balance" column for (every 3 cells) for Aidan together to get the total balance.

At the moment I am just doing the following but need it to accommodate an infinite amount of columns (fixtures) and be scalable because currently, this is not.

=SUM(Sheet1!D3, Sheet1!G3)

Any help would be massively appreciated.

Answer 1

you can use FILTER of MOD in SUM like:

=SUM(FILTER(B2:2, MOD(COLUMN(B2:2)+2, 3)=0))

Answer 2

Since the goal is to sum all values from columns with header "Balance", you could also do this:

=sumproduct(Sheet1!$B$2:$J$2="Balance",Sheet1!B3:J3)

That way you don't have to worry about the index of those columns, should you ever decide to add more columns to your sheet.
