The Spreadsheet editor is used to inspect geometry attributes, which is useful for debugging and working with Geometry Nodes.

Accessing Spreadsheet editor

To view the Spreadsheet editor, change the editor type to Spreadsheet (Figure 1).

How to read the Spreadsheet

First, choose an object (e.g. a mesh, curve, instance etc) from the Outliner. Then, choose a geometry domain (e.g. vertex, edge, face, etc). For each domain, its size is defined. For example, shown in Figure 2 we can see that a cube posses 8 vertexes, 12 edges, and 6 faces.

In the columns on the right of the panel are shown the attributes associated with that domain. For example, in Figure 2 is shown the x, y, z position data of each vertex of the cube.

Figure 2. Choosing Geometry Domain

The spreadsheet will also show the custom data created by Geometry Nodes, vertex groups, or any other means. For example, when creating a "Group" vertex group, Spreadsheet will simultaneously show an attribute called "Group". Any changes applied to this attribute will be shown accordingly in the Spreadsheet (figure 3).

Figure 3. Creating and modifying custom attribute

When working with advanced setups of Geometry Nodes, a large amount of attributes will be created. Understanding how to read Spreadsheets is the only way to know what these attributes are doing under the hood.
