I have data like this in Excel:
that I want to convert to a (5*7) matrix like this:
sara jone shery jack joe peter beti book1 1 0 0 0 0 0 0 book2 1 0 0 1 0 0 1 book3 0 0 0 0 0 1 0 book4 0 1 1 1 0 0 0 book5 0 0 1 0 1 0 0
What can I do?
My choice would be to rearrange the data to suit a PivotTable. So copy ColumnC and Paste Special Values into ColumnD. Then replace blanks in ColumnD with nothing (to remove the space from
book1, book2). Select ColumnD, Data > Data Tools – Text to Columns, Delimited, Comma then filter ColumnE to select non blank rows and copy the visible part of ColumnB (excluding header) to B9 (or to suit) and the visible part of ColumnE (excluding header) to D9 (or to suit). Then create your PivotTable from B1:D11 (or to suit) as shown (using ColumnD for
belong – ie
Starting in cell A2, paste your list of books to create the left side of your grid.
Copy your list of IDs, then starting In cell B2, paste your list of ids by selecting paste special, transpose. This will create the top and side of your matrix.
Paste this formula in Cell B2
(WHERE $K:$L is a listing of ids, belong. i.e. The second and third columns in your sample data. These can be anywhere as long as you update the reference $K:$L to refer to the new location)
Now, copy Cell B2, and paste for the rest of the matrix.
Just in case on book’s title could be found within another book’s title (for example “The Ring” and “Fellowship of the Ring”), you could use this formula in cell F2 and copy over and down to cell L6:
Where F1:L1 is the list of the names and E2:E6 is the list of book titles
