Hello,

I have a text file with the coordinates of a number of different
points, and I would like to plot them using the ListPointPlot3D
command. My text file is arranged like this:

x1 *tab* y1 *tab* z1 *tab* x2 *tab* y2 *tab* z2 *tab* x3 etc, with
nothing but tabs in between. Is it possible to have mathematica
automatically parse this file and insert brackets and commas in the
proper place, so the result would look like this:

{{x1, y1, z1}, {x2, y2, z2}, {x3, y3, z3}} etc?

Thank you very much,
cubsfan334

Assuming each item between tabs is a numeric item, then

Partition[ReadList[filename, Number],3]

will do what you want.
