Point-cloud applications, spreadsheets, and scripts may accept CSV rows but not compressed LAZ data. Converting exports each point’s coordinates and selected attributes into a table that those tools can read.
What the LAZ format is
LAZ is the compressed form of LAS, a format for storing lidar and other 3D point-cloud data. Files can contain XYZ coordinates plus attributes such as intensity, classification, return number, and color. Survey scanners, airborne lidar workflows, and photogrammetry software produce point clouds that are commonly delivered as LAZ; tools such as PDAL and CloudCompare also read or write it.
What the CSV format is
CSV stores rows of values separated by delimiters, usually commas. A point-cloud CSV typically has one row per point and columns for coordinates and chosen attributes, making the data accessible to spreadsheets, databases, and scripts. CSV is not a 3D point-cloud container: it does not inherently preserve spatial reference metadata, point-cloud organization, or all LAZ attributes.
How to convert LAZ to CSV
Online on 101convert.com
- Open the LAZ-to-CSV converter on 101convert.com and upload the LAZ file. The page supports batch conversion of several files; check its displayed per-file size limit.
- Start the conversion to CSV.
- Download the converted CSV file or files.
Offline with desktop software
PDAL is free, open-source point-cloud software available for Windows, macOS, and Linux. In a terminal, run:
pdal translate input.laz output.csv text --writers.text.format=csv --writers.text.order="X,Y,Z,Intensity,Classification"
Replace input.laz with the source filename and output.csv with the desired output path. The order option selects the exported columns; use dimensions present in the source file. For coordinates only, set it to X,Y,Z.
Quality and limitations
CSV is usually much larger than LAZ because it is plain text. Export only needed dimensions to limit file size. Coordinates are written as values, but the CSV does not reliably carry the LAZ file’s coordinate reference system, units, or scale metadata; retain that information separately. Attributes omitted from the selected export order are not included, and CSV does not preserve specialized point-cloud data such as waveform records.
