Give Back to Blender

Help funding Blender in 2026

If Blender helped you with your projects this year, we're asking you to help us back.

For the past year, you've had access to professional 3D software, completely free. No subscriptions, no licenses, no limits. Blender has been there for your projects, your learning, your art, your business.

Today, we're asking for $5.

That's it. If every active Blender user contributed $5 this month, Blender Foundation would meet its entire yearly funding goal for 2026.

Spreadsheet

The Spreadsheet editor is used to inspect the geometry attributes of theactive object,typically in order to debuggeometry nodes.

../_images/editors_spreadsheet_interface.png

The Spreadsheet editor.

Header

Show Only Selected

This option is only available if the object is in Edit Mode.When checked, only data for the selected geometry elements is shown.

Use Filter

Whether to use the filters that are defined in the Sidebar (see below).

View Menu

ToolbarT

Show or hide the tab panel on the left for creating and manipulating markers and masks.

SidebarN

Show or hide theSidebar.

Internal Attributes

Display attributes with names starting with a period that are meant for internal use.

Area

Area controls. See theuser interfacedocumentation for more information.

Main Region

The main region displays the attribute data in a spreadsheet format.Each column corresponds to an attribute or data property,and each row represents an element such as a vertex, face, spline, or instance.

Column names and row indices remain visible while scrolling both vertically and horizontally.

  • Columns can be resized by clicking and dragging the vertical line between columns.

  • Double clicking the vertical line automatically sizes the column to fit the content.

  • Columns can be reordered by clicking and dragging the column header.

Note

Tooltips give more detail about the value, depending on thetype.For example,Byte Color attributes are displayed as scene linear floats,but the actual integer values are displayed when hovering over the float values,andMatrix attribute values are only displayed in tooltips.

Data Set Region

Located on the left, this region controls which data is displayed in the spreadsheet.

Context Path

Displays the active object name in the panel header.

Clicking one of the arrows between the names to hide the modifier.

Clicking the icon locks the Spreadsheet editor to the currently active object and data path,keeping it visible even if you select another object. Click again to unlock.

Object Evaluation State

Defines which state of the object’s data is displayed:

Evaluated:

Shows data with all modifiers applied.

Original:

Shows the original object data, without modifiers.

Viewer Node:

Displays data from the activeViewer Node in GeometryNodes.

You can also toggle betweenEvaluated andViewer Node by clicking the / icon in the Viewer node’s header.

Viewer Path

Visible whenObject Evaluation State is set toViewer Node.

Shows the path from the modifier to the active viewer node.If the viewer node is nested inside group nodes, each group will appear in the path.

Viewer Data

Visible whenObject Evaluation State is set toViewer Node.

Specifies whichViewer Items from the active Viewer nodeis displayed in theSpreadsheet Editor.

When a Viewer node outputs multiple data sets (for example, geometry and one or more evaluated fields),each of these appears as a separateViewer Item.This setting allows choosing which item to display, such as a specific attribute, value field,or geometry component, without changing the Viewer node connection itself.

Note

The available viewer items depend on the currently active Viewer node and its connected inputs.Changing the active viewer or modifying its connections will update this list automatically.

Geometry

Lets you browse nested geometries (e.g., a mesh inside an instance or a geometry collection).

Domain

Lets you choose the attribute domain to display, such as mesh vertices or curve splines.

The number of elements in each domain is shown next to its entry.

Volume Grids

When the selected geometry component is aVolume, the Spreadsheet displays detailedinformation about each grid contained in the volume.Each grid represents a single data field, such asdensity,color, orvelocity,and can be inspected individually to understand its structure and memory usage.

The following information is shown for each grid:

  • Grid Name – The name of the grid data, such asdensity ortemperature.

  • Data Type – The type of data stored in the grid, for exampleFloat,Vector, orBoolean.

  • Class – The grid class, describing its purpose or usage,such asFog Volume,Level Set, orLevel Set.

  • Extent – The grid’s bounding box in voxel coordinates.Shows the number of voxels in the X, Y, and Z directions.

  • Voxels – The total number of active voxels in the grid.This includes all voxels that are explicitly stored, even when contained intiles(e.g., a single leaf tile contains 512 voxels).

  • Leaf Voxels – The number of active voxels stored inleaf nodes.UnlikeVoxels, this count excludes voxels that belong to higher-level tiles.

  • Tiles – The number of active tiles in the grid.Tiles are higher-level voxel containers used by sparse volume formats (like OpenVDB) to optimize storage.

  • Size – The estimated memory size of the grid, including all voxel and tile data currently allocated.

These statistics make it possible to analyze the complexity, density, and performance cost ofvolumetric data produced by Geometry Nodes or imported volume files.

Note

Since volume grids use a sparse data structure, theExtent can be much larger than the actualnumber of active voxels. Only active regions of the grid are stored in memory, which keepsvolume data efficient even for large domains.

Sidebar

In the Sidebar, you can define filters so that only the rows matching these filtersare displayed. ClickAdd Row Filter and set up the properties described below.

Enabled

Uncheck to temporarily disable the filter.

Column

The name of the column to filter on. If there is no column with the specified name,the filter will be grayed out and ignored.

If you want to filter on an attribute from another domain, you can use theStore Named Attribute Node to create a copythat’s converted to the current domain, then filter on that.

Operation

For numerical columns, you can select one of the following comparison operators.Other columns only supportEqual To.

Equal To:

Only display rows whose value for the column is equal to the filter value(within the specified threshold).

Greater Than:

Only display rows whose value for the column is greater than the filter value.

Less Than:

Only display rows whose value for the column is less than the filter value.

Value

The filter value to compare the row value to.

Threshold

How much the row’s value is allowed to deviate from the filter value before it is excluded.

Status Bar

The status bar shows how many rows and columns there are, and how many rows remain after filtering.
