What is a .XYZ file?
XYZ is a simple text list of atoms and their 3D coordinates.
- Did you know
- The XYZ format is the plainest way to record where every atom in a molecule sits.
- The XYZ format originated in the XMol visualisation software at the University of Minnesota.
- An XYZ file starts with a line giving the number of atoms, then a free-text comment line, before listing each atom’s element and coordinates.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .XYZ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .XYZ file
- Drag a .XYZ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
