Point-cloud applications may need LAS data as CSV for import into spreadsheet, analysis, or modeling tools that accept coordinate tables. CSV also makes individual point coordinates and selected attributes easier to inspect or share as plain text.
What LAS contains
LAS is an ASPRS binary format for lidar point clouds. Each point can contain coordinates and attributes such as intensity, classification, return information, and color; files can also store coordinate reference information. Surveying and lidar capture or processing software, including ArcGIS and TerraScan, commonly produces or handles LAS files.
What CSV contains
CSV stores tabular values as rows and comma-separated fields, so it can be opened in spreadsheet programs and imported by many data and modeling tools. A point-cloud CSV typically uses one row per point, with columns such as X, Y, Z and optional attributes. Unlike LAS, CSV does not standardize point-cloud metadata or coordinate reference system information.
How to convert
Online on 101convert.com
- Upload the LAS file to the converter on the page.
- Choose CSV as the output format and start the conversion.
- Download the converted file when it is ready. For batch conversion, add multiple files; the per-file size limit is shown on the page.
Offline with desktop software
PDAL is free, open-source point-cloud software available for Windows, macOS, and Linux. Install PDAL, open a terminal in the folder containing the LAS file, then run pdal translate input.las output.csv writers.text --writers.text.order="X,Y,Z,Intensity,Classification". This writes the listed dimensions as CSV columns; change the input and output filenames as needed. If you need other attributes, include their dimension names in the order option.
Quality and limitations
CSV export can omit LAS attributes unless they are selected as columns. The example retains coordinates, intensity, and classification; check the output header and rows against the required fields. LAS coordinate reference information is not carried as standardized CSV metadata, so record the CRS and coordinate units separately. Large point clouds can produce very large CSV files, and CSV does not preserve LAS-specific structure or metadata.
