I have an excel spreadsheet that I would like to plot in a 3D graph using mathematica. The X and Y values are the location of the cell, and the Z value is the number of the scale.

How can I import this into mathematica for plotting purposes?

Here is what my data looks like. enter image description here

You can factor your Q into two parts: (1) data = Import["myFile.xls"] (if the file contains only a single worksheet, otherwise take parts). (2) Then you can transform this data to Graphics3D in a variety of ways. – alancalvitti Jan 25 '13 at 18:46
@alancalvitti that worked... if you add it as an answer I will select it. – Sponge Bob Jan 25 '13 at 19:07

Flatten[MapIndexed[{Sequence @@ #2, #1} &, 
                Import["ExampleData/elements.xls"] [[1]], {2}], 1] // TableForm

Requested explanation:


Gets the first sheet in the file

MapIndexed[{Sequence @@ #2, #1} &, ...... , {2}]

Generates tuples of the form {posx, posy, cellValue}

Flatten[........, 1]

Gets rid of extra nesting levels on the resulting list

// TableForm

Formats the output you see below

This works great. Thank you. Do you think you could explain what it is doing, please? – Sponge Bob Jan 25 '13 at 19:41
