CSV Importer
CSV Importer
A simple and fast CSV file importer.
How to Use
Option 1: Drag and drop your CSV file directly into Blender’s viewport.
Option 2: Use the menu: File → Import → CSV
Using the Data
The imported data will be stored in a mesh.
The mesh consists of only vertices, with no faces and no edges.
All vertices are placed at the same point: the Origin (0,0,0).
Each vertex contains attributes from the imported data.
The data will appear in Blender’s Spreadsheet Editor.
Use Geometry Nodes and the Named Attribute feature to set new vertex positions based on the imported data.
Find additional documentation in the Github README.
Sample dataset download: data_california_housing_normalized.csv
If you see this message: "Extension bl_ext.blender_org.csv_importer is incompatible (This Python version (3.11) isn't compatible with (3.9)" , then update to Blender4.3 and it should work.
What's New
0.1.8 March 13th, 2025
Changelog
Version 0.1.8
- Improved default data visualization by distributing points randomly in 3D space (values between 0-1 on each axis) instead of stacking all points at the origin
- For performance reasons, the number of unique strings is limited to 3000 by default (processing this many strings takes about 7 seconds on a Mac M3)
- Note: This limit applies to the number of unique strings, not the total count. For example, a CSV with 100,000 strings but only 100 unique values won't be affected by the limit.
- You can override this limit when using the API directly:
import string
import numpy as np
import polars as pl
from csv_importer.parsers import polars_df_to_bob
n = 4000
random_strings = [''.join(np.random.choice(list(string.ascii_lowercase), size=10)) for _ in range(n)]
df = pl.DataFrame({"strings": random_strings, "numbers": np.arange(n)})
bob = polars_df_to_bob(df, name="TestBob",string_limit =4001)
Hi. This looks useful. Thank you for doing it. I have installed and activated the add-on, but it takes a long time to import any csv. At first, I thought that Blender froze, but I left it running for a few minutes and the data finally did import. That was using the sample data provided. It happens if I drag and drop the csv or import through file>import>csv. I'm running Blender 4.3.2. I've tried running a "repair" of Blender and reinstalling the addon, but the issue persists. Has anyone had this issue?
This looks extremely useful, but I'm having issues activating it: "Extension bl_ext.blender_org.csv_importer is incompatible (This Python version (3.11) isn't compatible with (3.9))". Any ideas how to fix this? I'm on Windows and Blender 4.3.0
Looks great but seem to have an issue in that: it installs and then is no longer visible in the import section upon restarting Blender? Am using V4.3.2. Any thoughts? Thanks!
