# math – How do transform a "matrix"-table to one line for each entry in excel

Questions:

I have something like

``````  1  2  3
a x  o  x
b x  x  o
c o  o  o
``````

and want to transform it into lines like

``````1 a x
1 b x
1 c x
2 a o
2 b x
2 c o
3 a x
3 b o
3 c o
``````

by using a formula in the excel document. Playing with \$ for assigning values for each row and column does give me proper results. Each time I have to do some manual changes to the formula.
Any hint how to write it the right way?

Suppose that your matrix in the cells A1:D4

in A6 put:

``````=OFFSET(\$A\$1;0;QUOTIENT(ROW()-ROW(\$A\$6);3)+1)
``````

in B6 put:

``````=OFFSET(\$A\$1;MOD(ROW()-ROW(\$A\$6);3)+1;0)
``````

in C6 put:

``````=VLOOKUP(\$B6;\$A\$1:\$D\$4;MATCH(\$A6;\$A\$1:\$D\$1;0);FALSE)
``````

Den drag down (copying formulas) A6:C6 up to A14:C14

(I translate my formulas from italian so there could be some glitch)

PS: 3 in the formulas refers to the number of rows (and column) of the example.
