Definition
The XYZ format is one of the simplest ways to store a point cloud. Each line in an XYZ file lists a single point by its three coordinates, X, Y, and Z, and sometimes extra values like colour, in plain text.
Because it is so straightforward and human-readable, XYZ is easy to create, open, and understand. It is a basic, universal way to hold 3D point data, though it lacks some of the richer features of specialised formats.
In simple terms, an XYZ file is a plain text list of 3D points written out as coordinates.
How It Works
An XYZ file stores each point on its own line as numbers separated by spaces or commas, giving the point’s position in three dimensions. Some variations add further columns for colour or other attributes after the coordinates.
Since it is just readable text with no complex structure, almost any program can import or export XYZ data. The trade-off is that plain text files can be large and slower to handle than compact binary formats, and they carry limited extra information.
Applications
The XYZ format is used in surveying, research, and 3D data exchange. It is handy for sharing simple point data between different tools, quick inspection of coordinates, and situations where a straightforward, universal format is preferred.

Frequently Asked Questions
What is the XYZ format used for?
It is used to store and share simple point cloud data as plain text coordinates between different tools.
What does an XYZ file contain?
Each line lists a point’s X, Y, and Z coordinates, sometimes with extra values like colour.
What are the limits of the XYZ format?
As plain text, files can be large and slower to handle, and it carries less structure than specialised formats.
Is the XYZ format widely supported?
Yes, because it is so simple, almost any 3D program can read or write XYZ data.
